[Cronos]

In 325 AD, Constintine became a Christian and adopted Christianity as the state religion--the origin of the Roman Church.

That Is WRONG. The origin of the Roman church is when the first bishop of Rome -- Peter -- taught there. The origins of the Catholic church start in Jerusalem when the Apostles received the holy Spirit.

[Just mythoughts]

Why do you suppose there are 7 different churches listed in Revelation?

John was taken in "SPIRIT" on the Lords DAY, and that DAY has not begun.

Now a message was given to each of these churches about their standing and only two had no problems.
