“‘Ecumenism’ is a heresy only if it actually involves the denial that Orthodoxy is the true Church of Christ. A few of the Orthodox leaders of the ecumenical movement have gone this far; but most Orthodox participants in the ecumenical movement have not said this much; and a few (such as the late Fr. Georges Florovsky) have only irritated the Protestants in the ecumenical movement by frequently stating at ecumenical gatherings that Orthodoxy is the Church of Christ.”
(Fr. Seraphim Rose+) [True Church; Witness]
