Polish Catholic leaders have issued a formal open letter condemning the Vatican Synod on Synodality's Final Document, warning it replaces unchanging Church doctrine with an 'ideology of inclusivity' and distorts the Eucharist, priesthood, and Marian devotion. This fracturing of the institutional Church from within mirrors the biblical warning of a great apostasy — a falling away from sound doctrine in the last days before Christ's return. Scripture warns that in the end times many will 'not endure sound teaching' but will gather teachers to suit their own desires, and that a great apostasy must come before the Day of the Lord (2 Thess 2:3; 2 Tim 4:3-4).
