Heresy and the lie are as old

as humanity and the Church.

From the original fall, the devil, whom Our Lord calls the “father of the lie” (Jn 8:44), seduced Eve by a direct lie and introduced sin into the human race. This initial deception has generated all the errors that have multiplied among men.

In the Church founded by Christ, heresy appeared from apostolic times. The epistles of St. Paul and St. John bear witness to false teachers and antichrists who already opposed the revealed doctrine while the Apostles were still alive. The history of the Church then shows the uninterrupted succession of these errors down to our own days.
