Fr. Seraphim Rose Orthodoxy And The Religion Of The Future: Introduction Chapter 1

Hieromonk Seraphim Rose warns that modern Ecumenism is leading to the dissolution of Orthodox Christianity by engaging in interfaith dialogue with non-Christian religions. He criticizes Orthodox theologians and clergy for participating in meaningless "dialogues" with Catholics, Protestants, Muslims, Hindus, Buddhists, and Jews without asserting the exclusive truth of Orthodoxy.

He argues that this movement, driven by Masonic ideology, does not seek Christian unity but rather a global syncretic religion that merges all faiths into one. Events like the World Council of Churches (WCC) conferences, interfaith prayer services, and theological discussions show a shift from Christianity to a universal religious system where all beliefs are considered equally valid.

Examples include:

The Greek Orthodox Archdiocese calling for all religions to unite (1968).
Orthodox clergy participating in interfaith "summits" and shared worship.
A Greek Orthodox-Jewish dialogue (1972) leading to changes in Orthodox liturgical texts to be more "inclusive."
Rose sees these developments as a betrayal of Christian truth, accelerating the formation of a false, Antichrist-centered religion. He warns Orthodox Christians to remain steadfast in traditional faith and reject the deceptive spirit of interfaith ecumenism.
