The Love of Christ Compels Us (2 Cor. 5:14):
Fifty Years of Theological Dialogue
The North American Orthodox-Catholic Theological Consultation October 24, 2015
We give thanksgiving and praise to God, Father, Son and Holy Spirit, for the blessed opportunity to observe the fiftieth anniversary of the establishment of the North American Orthodox-Catholic Theological Consultation, in Worcester, Massachusetts, October 22-24, 2015.
The first meeting of the Consultation took place on September 9, 1965, at St. Spyridon Greek Orthodox Cathedral in Worcester, under the leadership of Archbishop Iakovos (+2005) of the Greek Orthodox Archdiocese of North and South America and Bishop Bernard Flanagan (+1998) of Worcester. This unprecedented gathering of theologians occurred after the historic meeting of Pope Paul VI and Ecumenical Patriarch Athenagoras in Jerusalem on January 5, 1964, and prior to the lifting of the anathemas of 1054 by Rome and Constantinople on December 7, 1965.
The Orthodox-Catholic Theological Consultation had been formally established earlier in 1965 by the Standing Conference of Canonical Orthodox Bishops in America, now the Assembly of Canonical Orthodox Bishops of the United States, and by the National Conference of Catholic Bishops, now the United States Conference of Catholic Bishops. Since 1997, the Canadian Conference of Catholic Bishops has also been a co-sponsor.
The 1983 Anathema Against Ecumenism:
Those who attack the Church of Christ by teaching that Christ’s Church is divided into so-called “branches” which differ in doctrine and way of life, or that the Church does not exist visibly, but will be formed in the future when all “branches” or sects or denominations, and even religions will be united into one body; and who do not distinguish the priesthood and mysteries of the Church from those of the heretics, but say that the baptism and eucharist of heretics is effectual for salvation; therefore, to those who knowingly have communion with these aforementioned heretics or who advocate, disseminate, or defend their new heresy of Ecumenism under the pretext of brotherly love or the supposed unification of separated Christians, Anathema!
