The AntiChrist would have to be a false pope St. Bernard
Any time you hear or see the phrase, Restoration, or the like, denies divine revelation that the first AntiChrist was Paul VI and that the final solution can only be the Second Coming of Christ. Do no trust Traditionalists who preach or indicate, Restoration, Sedeprivationists, material formula popes, interregnum, a future Pope, etc, on these subjects. You notice that I use a capitol C on AntiChrist, which means he has to be a priest, or acting priest.
They are all denying Scriptures. St. Bernard voiced his opinion that the AntiChrist would have to be a false pope. Not an Anti-Pope. An Anti-Pope can still be Catholic. An AntiChrist has to be an apostate.
