For over fifteen hundred years the Eastern (Byzantine) Orthodox churches and the Oriental Orthodox churches have remained separated. Only thirty years ago they came together for the first of four unofficial theological consultations : Aarhus (1964), Bristol (1967), Geneva (1970) and Addis Ababa (1971).
These were followed by the establishment of a Joint Commission of the Theological Dialogue between the Orthodox Church and the Oriental Orthodox Churches, which has held four meetings : Chambesy, Geneva (December 1985), Anba Bishoy monastery, Egypt (June 1989), Chambesy II (September 1990) and Chambesy III (November 1993).
Members of the Joint Commission included official representatives of the Coptic Orthodox Church, the Syrian Orthodox Patriarchate of Antioch and All the East, the Supreme Catholicosate of All Armenians at Etchmiadzin, the Armenian Catholicosate of Cilicia, the Malankara Orthodox Syrian Church of the East and the Ethiopian Orthodox Church from the Oriental Orthodox family; the Ecumenical Patriarchate, the Greek Orthodox Patriarchate of Alexandria, the Greek Orthodox Patriarchate of Antioch, the Russian Patriarchate, the Romanian Patriarchate, the Serbian Patriarchate, the Bulgarian Patriarchate, the Georgian Patriarchate, the Church of Cyprus, the Church of Greece, the Church of Albania, the Czechoslovakian Orthodox Church, the Polish Orthodox Church and the Finnish Orthodox Church from the Byzantine Orthodox family.
First Agreed Statement (1989)
We have inherited from our fathers in Christ the one apostolic faith and tradition, though as Churches we have been separated from each other for centuries. As two families of Orthodox Churches long out of communion with each other we now pray and trust in God to restore that communion on the basis of the common apostolic faith of the undivided church of the first centuries which we confess in our common creed. What follows is a simple reverent statement of what we do believe on our way to restore communion between our two families of Orthodox Churches.
Throughout our discussions we have found our common ground in the formula of our common Father, St. Cyril of Alexandria : mia physis hypostasis (he mia hypostasis) tou Theou Logou sesarkomene, and in the dictum that "it is sufficient for the confession of our true and irreproachable faith to say and to confess that the Holy Virgin is Theotokos" (Hom : 15, cf. Ep. 39).
Great indeed is the wonderful mystery of the Father, Son and Holy Spirit, one True God, one ousia in three hypostases or three prosopa. Blessed be the Name of the Lord our God, for ever and ever.
Great indeed is also the ineffable mystery of the Incarnation of our Lord Jesus Christ, for us and for our salvation.
The Logos, eternally consubstantial with the Father and the Holy Spirit in His Divinity, has in these last days, become incarnate of the Holy Spirit and Blessed Virgin Mary Theotokos, and thus became man, consubstantial with us in His humanity but without sin. He is true God and true Man at the same time, perfect in His Divinity, perfect in His humanity. Because the one she bore in her womb was at the same time fully God as well as fully human we call the Blessed Virgin Theotokos.
When we speak of the one composite (synthetos) hypostasis of our Lord Jesus Christ, we do not say that in Him a divine hypostasis and a human hypostasis came together. It is that the one eternal hypostasis of the Second Person of the Trinity has assumed our created human nature in that act uniting it with His own uncreated divine nature, to form an inseparably and unconfusedly united real divine-human being, the natures being distinguished from each other in contemplation (theoria) only.
The hypostasis of the Logos before the incarnation, even with His divine nature, is of course not composite. The same hypostasis, as distinct from nature, of the Incarnate Logos, is not composite either. The unique theandric person (prosopon) of Jesus Christ is one eternal hypostasis Who has assumed human nature by the Incarnation. So we call that hypostasis composite, on account of the natures which are united to form one composite unity. It is not the case that our Fathers used physis and hypostasis always interchangeably and confused the one with the other. The term hypostasis can be used to denote both the person as distinct from nature, and also the person with the nature, for a hypostasis never in fact exists without a nature.
It is the same hypostasis of the Second Person of the Trinity, eternally begotten from the Father Who in these last days became a human being and was born of the Blessed Virgin. This is the mystery of the hypostatic union we confess in humble adoration - the real union of the divine with the human, with all the properties and functions of the uncreated divine nature, including natural will and natural energy, inseparably and unconfusedly united with the created human nature with all its properties and functions, including natural will and natural energy. It is the Logos Incarnate Who is the subject of all the willing and acting of Jesus Christ.
We agree in condemning the Nestorian and the Eutychian heresies. We neither separate nor divide the human nature in Christ from His divine nature, nor do we think that the former was absorbed in the latter and thus ceased to exist.
The four adverbs used to qualify the mystery of the hypostatic union belong to our common tradition - without commingling (or confusion) (asyngchytos), without change (atreptos), without separation (achoristos) and without division (adiairetos). Those among us who speak of two natures in Christ, do not thereby deny their inseparable, indivisible union; those among us who speak of one united divine-human nature in Christ do not thereby deny the continuing dynamic presence in Christ of the divine and the human, without change, without confusion.
Our mutual agreement is not limited to Christology, but encompasses the whole faith of the one undivided church of the early centuries. We are agreed also in our understanding of the Person and Work of God the Holy Spirit, Who proceeds from the Father alone, and is always adored with the Father and the Son. 
Second Agreed Statement (1990)
The first Agreed Statement on Christology adopted by the Joint Commission of the Theological Dialogue between the Orthodox and Oriental Orthodox Churches, at our historic meeting at the Anba Bishoy Monastery, Egypt, from 20th to 24th June 1989 forms the basis of this Second Agreed Statement on the following affirmations of our common faith and understanding, and recommendations on steps to be taken for the communion of our two families of Churches in Jesus Christ our Lord, Who prayed "that they all may be one".
1. Both families agree in condemning the Eutychian heresy. Both families confess that the Logos, the Second Person of the Holy Trinity, only begotten of the Father before the ages and consubstantial with Him, was incarnate and was born from the Virgin Mary Theotokos; fully consubstantial with us, perfect man with soul, body and mind (nouj); He was crucified, died, was buried, and rose from the dead on the third day, ascended to the Heavenly Father, where He sits on the right hand of the Father as Lord of all Creation. At Pentecost, by the coming of the Holy Spirit He manifested the Church as His Body. We look forward to His coming again in the fullness of His glory, according to the Scriptures.
2. Both families condemn the Nestorian heresy and the crypto-Nestorianism of Theodoret of Cyrus. They agree that it is not sufficient merely to say that Christ is consubstantial both with His Father and with us, by nature God and by nature man; it is necessary to affirm also that the Logos, Who is by nature God, became by nature Man, by His Incarnation in the fullness of time.
3. Both families agree that the Hypostasis of the Logos became composite (sunqetoj) by uniting to His divine uncreated nature with its natural will and energy, which He has in common with the Father and the Holy Spirit, created human nature, which He assumed at the Incarnation and made His own, with its natural will and energy.
4. Both families agree that the natures with their proper energies and wills are united hypostatically and naturally without confusion, without change, without division and without separation, and that they are distinguished in thought alone (th qewria monh). 20
5. Both families agree that He Who wills and acts is always the one Hypostasis of the Logos incarnate.
6. Both families agree in rejecting interpretations of Councils which do not fully agree with the Horos of the Third Ecumenical Council and the letter (433) of Cyril of Alexandria to John of Antioch.
7. The Orthodox agree that the Oriental Orthodox will continue to maintain their traditional Cyrillian terminology of "one nature of the incarnate Logos" ("mia fusij tou qeou Logou sesarkwmenh"), since they acknowledge the double consubstantiality of the Logos which Eutyches denied. The Orthodox also use this terminology. The Oriental Orthodox agree that the Orthodox are justified in their use of the two-natures formula, since they acknowledge that the distinction is "in thought alone" (th qewria monh). Cyril interpreted correctly this use in his letter to John of Antioch and his letters to Acacius of Melitene (PG 77, 184-201), to Eulogius (PG 77, 224-228) and to Succensus (PG 77, 228-245).
8. Both families accept the first three Ecumenical Councils, which form our common heritage. In relation to the four later Councils of the Orthodox Church, the Orthodox state that for them the above points 1-7 are the teachings also of the four later Councils of the Orthodox Church, while the Oriental Orthodox consider this statement of the Orthodox as their interpretation. With this understanding, the Oriental Orthodox respond to it positively.
In relation to the teaching of the Seventh Ecumenical Council of the Orthodox Church, the Oriental Orthodox agree that the theology and practice of the veneration of icons taught by that Council are in basic agreement with the teaching and practice of the Oriental Orthodox from ancient times, long before the convening of the Council, and that we have no disagreement in this regard.
9. In the light of our Agreed Statement on Christology as well as of the above common affirmations, we have now clearly understood that both families have always loyally maintained the same authentic Orthodox Christological faith, and the unbroken continuity of the apostolic tradition, though they have used Christological terms in different ways. It is this common faith and continuous loyalty to the Apostolic Tradition that should be the basis for our unity and communion.
10. Both families agree that all the anathemas and condemnations of the past which now divide us should be lifted by the Churches in order that the last obstacle to the full unity and communion of our two families can be removed by the grace and power of God. Both families agree that the lifting of anathemas and condemnations will be consummated on the basis that the Councils and Fathers previously anathematized or condemned are not heretical.
We therefore recommend to our Churches the following practical steps :
A. The Orthodox should lift all anathemas and condemnations against all Oriental Orthodox Councils and Fathers whom they have anathematised or condemned in the past.
B. The Oriental Orthodox should at the same time lift all anathemas and condemnations against all Orthodox Councils and fathers, whom they have anathematised or condemned in the past.
C. The manner in which the anathemas are to be lifted should be decided by the Churches individually.
Trusting in the power of the Holy Spirit, the Spirit of Truth, Unity and Love, we submit this Agreed Statement and Recommendations to our venerable Churches for their consideration and action, praying that the same Spirit will lead us to that unity for which our Lord prayed and prays.
Recommendations on Pastoral Issues (1990)
The Joint Commission of the Theological Dialogue between the Orthodox Church and the Oriental Orthodox Churches, at its meeting at the Orthodox Centre of the Ecumenical Patriarchate, in Chambesy, Geneva from September 23rd to 28th 1990, received a report from its Joint Pastoral Sub-committee which had met at the Anba Bishoy Monastery in Egypt from 31st January to 4th February 1990. The report was the starting point for an extended discussion of four types of pastoral issues :
I. Relations among our two families of Churches, and our preparation for unity.
II. Relations of our Churches with other Christian Churches and our common participation in the Ecumenical Movement.
III. Our common service to the world of suffering, need, injustice and conflicts.
IV. Our co-operation in the propagation of our common faith and tradition.
I. Relations among our two families of Churches
1. We feel as a Joint Theological Commission that a period of intense preparation of our people to participate in the implementation of our recommendations and in the restoration of communion of our Churches is needed. To this end we propose the following practical procedure.
2. It is important to plan an exchange of visits by our heads of Churches and prelates, priests and lay people of each one of our two families of Churches to the other.
3. It is important to give further encouragement to exchange of theological professors and students among theological institutions of the two families for periods varying from one week to several years.
4. In localities where Churches of the two families co-exist, the congregations should organise participation of one group of people - men, women, youth and children, including priests, where possible from one congregation of one family to a congregation of the other to attend in the latter's eucharistic worship on Sundays and feast days.
5. Publications (a) We need to publish, in the various languages of our Churches, the key documents of this Joint Commission with explanatory notes, in small pamphlets to be sold at a reasonable price in all our congregations.
(b) It will be useful also to have brief pamphlets explaining in simple terms the meaning of the Christological terminology and interpreting the variety of terminology taken by various persons and groups in the course of history in the light of our Agreed Statement on Christology.
(c) We need a book which gives some brief account, both historical and descriptive, of all the Churches of our two families. This should also be produced in the various languages of our peoples, with pictures and photographs as much as possible.
(d) We need to promote brief books of Church History by specialist authors giving a more positive understanding of the divergencies of the fifth, sixth and seventh centuries.
6. Churches of both families should agree that they will not rebaptize members of each other, for recognition of the baptism of the Churches of our two families, if they have not already done so.
7. Churches should initiate bilateral negotiations for facilitating each other in using each other's church premises in special cases where any of them is deprived of such means.
8. Where conflicts arise between Churches of our two families, e.g. a) marriages consecrated in one Church being annulled by a bishop of another Church; b) marriages between members of our two families, being celebrated in one church over against the other, c) or children from such marriages being forced to join the one church against the other, the Churches involved should come to bilateral agreements on the procedure to be adopted until such problems are finally solved by our union.
9. The Churches of both families should be encouraged to look into the theological curriculum and books used in their institutions and make necessary additions and changes in them with the view to promoting better understanding of the other family of Churches. They may also profitably devise programmes for instructing the pastors and people in our congregations on the issues related to the union of the two families.
II. Relations of our Churches with other Christian Churches in the world
10. Our common participation in the Ecumenical Movement and our involvement in the World Council of Churches needs better co-ordination to make it more effective and fruitful for the promotion of the faith which was once delivered to the saints in the context of the Ecumenical Movement. We could have a preliminary discussion of this question at the Seventh Assembly of the W.C.C. at Canberra, Australia, in February 1991 as well as in regional and national councils of Churches and work out an appropriate scheme for more effective co-ordination of our efforts.
11. There are crucial issues in which our two families agree fundamentally and have disagreements with the Roman Catholic and Protestant Churches. We could organise small joint consultations on issues like
(a) the position and role of the woman in the life of the Church and our common Orthodox response to the contemporary problem of other Christian communities concerning the ordination of women to the priesthood,
(b) pastoral care for mixed marriages between Orthodox and heterodox Christians,
(c) marriages between Orthodox Christians and members of other religions,
(d) the Orthodox position on dissolution or annulment of marriage, divorce and separation of married couples,.
12. A joint consultation should be held on the burning problem of Proselytism, vis-a-vis religious freedom to draw up the framework of an agreement with other Churches, for the procedure to be followed when an Orthodox or Oriental Orthodox person or family want to join another (Catholic or Protestant) Church or vice-versa.
13. A special joint consultation should be held on the theology and practice of Uniatism in the Roman Catholic Church, as a prelude to a discussion with the Roman Catholic Church on this subject.
14. We need to have another joint consultation to co-ordinate the results of the several bilateral conversations now going on or held in the past by Churches of our two families with other Catholic and Protestant Churches.
III. Our common service to the world of suffering need, injustice and conflicts
15. We need to think together how best we could co-ordinate our existing schemes for promoting our humanitarian and philanthropic projects in the socio-ethnic context of our peoples and of the world at large. This would entail our common approach to such problems as :
(a) hunger and poverty,
(b) sickness and suffering,
(c) political, religious and social discrimination,
(d) refugees and victims of war,
(e) youth, drugs and unemployment,
(f) the mentally and physically handicapped,
(g) the old and the aged)
IV. Our co-operation in the propagation of the Christian Faith
16. We need to encourage and promote mutual co-operation as far as possible in the work of our inner mission to our people, i.e. in instructing them in the faith, and how to cope with modern dangers arising from contemporary secularism, including cults, ideologies, materialism, AIDs, homosexuality, the permissive society, consumerism, etc.
17. We also need to find a proper way for collaborating with each other and with other Christians in the Christian mission to the world without undermining the authority and integrity of the local Orthodox Churches.
Proposals for Lifting of Anathemas agreed at Chambesy, Geneva, 1st-6th November 1993
1. In the light of our Agreed Statement on Christology at St. Bishoy Monastery 1989, and of our Second Agreed Statement at Chambesy 1990, the representatives of both Church families agree that the lifting of anathemas and condemnations of the past can be consummated on the basis of their common acknowledgement of the fact that the Councils and Fathers previously anathematized or condemned are Orthodox in their teachings. In the light of our four unofficial consultations (1964, 1967, 1970, 1971) and our three official meetings which followed on (1985, 1989, 1990), we have understood that both families have loyally maintained the authentic Orthodox Christological doctrine and the unbroken continuity of the apostolic tradition, though they may have used Christological terms in different ways.
2. The lifting of the anathemas should be made unanimously and simultaneously by the Heads of all the Churches of both sides, through the signing of an appropriate ecclesiastical Act, the content of which will include acknowledgements from each side that the other one is Orthodox in all respects.
3. The lifting of the anathemas should imply :
a. that restoration of full communion for both sides is to be immediately implemented;
b. that no past condemnation, synodical or personal, against each other is applicable any more;
c. that a catalogue of Diptychs of the Heads of the Churches should be agreed upon to be used liturgically.
4. At the same time the following practical steps should be taken :
a. The Joint Sub-Committee for Pastoral issues should continue its very important task according to what had been agreed at the 1990 meeting of the Joint Commission.
b. The co-chairmen of the Joint Commission should visit the Heads of the Churches with the view to offering fuller information on the outcome of the Dialogue.
c. A Liturgical Sub-Committee should be appointed by both sides to examine the liturgical implications arising from the restoration of communion and to propose appropriate forms of concelebration.
d. Matters relating to ecclesiastical jurisdiction should be left to be arranged by the respective authorities of the local churches according to common canonical and synodical principles.
e. The two co-chairmen of the Joint Commission with the two Secretaries of the Dialogue should make provisions for the production of appropriate literature explaining our common understanding of the Orthodox faith which has led us to overcome the divisions of the past, and also co-ordinating the work of the other Sub-Committees.
