Ecumenism is a cocktail of various peculiar religious beliefs and eccentric philosophies. It is unacceptable syncretism. Everything fits within it – truth and lies, Orthodoxy and heresy. Ecumenism resembles a collapsing roof, beneath which exists everything that humankind can think of. It is a lie most difficult to discern, yet an attractive lie, which tests the conscience, one’s determination, and one’s faith. It is a charming “nothing”, which takes on an existential “hypostasis” within the soul of those who have not experienced the fullness of Orthodoxy, and who have not found “rest for their souls” https://orthodoxreflections.com/the-lie-of-ecumenism/
