Fr. Seraphim Rose Orthodoxy And The Religion Of The Future: Chapter 2

The text criticizes ecumenism, particularly the dialogue with non-Christian religions, as a dangerous departure from traditional Christianity. The author distinguishes between:

Christian ecumenism, where Protestants and Catholics seek unity but fail to recognize that the true Church of Christ already exists.
Non-Christian ecumenism, which goes further by attempting to find unity with religions that reject Christ altogether.
The author argues that true Christian unity cannot exist outside the Church, and that engaging in religious dialogue with non-Christian faiths leads to spiritual compromise. He criticizes figures like Metropolitan Georges Khodre, who suggest that the Holy Spirit is at work in all religions, independent of Christ and the Church. This idea, the author asserts, undermines the Trinity and is a heresy designed to weaken Christianity.

The text warns against reducing Christ to just another spiritual experience or treating different religions as equal. It argues that the ecumenical movement is paving the way for a false, universal spirituality that distances people from true Christianity.
