Yes, I'm aware of major chunks of the Vatican edifice have believed Amillenialism for a long time.
Are you under the illusion that I have thought highly of the Vatican's eschatology?
Actually, I am surprised that you would approach the Church's teachings as one would view a buffet table. If what comes out of the Vatican is mere opinion that one can freely choose to accept or discard, how is it that you can challenge a Protestant regarding their scepticism of certain Roman teachings and traditions?
