That’s why we need to stick to God’s Church, not man’s grotesque misinterpretation of His Scripture.

That's why we need a Roman Emperor to tell us what to do? Not buying it. While we're on that subject, which pope was it who decided to institute the celibate priesthood? Because it hasn't been around for the entire history of the Church, right?

Also, when was it decreed that Mary didn't die, but was "Assumed" (I guess that's the word; whatever the root of "Assumption Day" is) into heaven?

From the 5th Century: The Feast of the Assumption of Mary was celebrated in Syria.

The same testimony is clear also in the Western Church (Gregory, Tours, 538-594).
