St. Justin Popovich: . . . the dogma of papal infallibility is not only a heresy but the greatest heresy against the True Church of Christ . . .

Icon of St. Justin Popovich“With respect to the dogma concerning papal infallibility, as a particular matter the pope has been proclaimed to be the Church, and the pope─a man─has usurped the place of the God-man. That is the ultimate triumph of humanism and simultaneously “the second death” (Rev. 20: 14, 21:8) of the papacy, and through it and after it the death of every humanism. However, the dogma of papal infallibility is not only a heresy but the greatest heresy against the True Church of Christ, which has existed in our terrestrial world as a theanthropic body ever since the appearance of the God-man. No other heresy has revolted so violently and so completely against the God-man Christ and His Church as has the papacy with the dogma of the pope-man’s infallibility. There is no doubt about it. This dogma is the heresy of heresies, a revolt without precedent against the God-man Christ on this earth, a new betrayal of Christ, a new crucifixion of the Lord, this time not on wood but on the golden cross of papal humanism. And these things are hell, damnation for the wretched earthly being called man.”
