How can one identify the Antichrist; can he be a Bishop opposing the Papacy in relation to 1 John 2:19-20?

**Will the Antichrist come from the Catholic Church?** Perhaps since the Antichrist was a real person, is it possible that he is like a Cardinal or Bishop infected by the spirit of Antichrsti? According to St. John's epistle (1 John 2:19-20); > They went out from us, but they did not really belong to us. For if > they had belonged to us, they would have remained with us, but their > going showed that none of them belonged to us. Is St. John talking about the future Bishops or presbyters will become the Anti-Christ who belong to the Catholic Church but separated themselves in a form of schism? Does Catholic Church have a teaching that one of the Bishops or Cardinals will be the Antichrist?
