Who was the first Roman Emperor to be become a Christian?

Answer 1

Constantine the Great was the first Roman Emperor who supported Christianity. However, he got baptised only just before his death, and during his rule he retained his position as pontifex maximus, the high priest of Roman religion. He also associated himself with Sol Invictus/Apollo, the sun god and had a statue of himself as the sun god erected in Constantinople. He also encouraged the worship of he sun god and decreed that Sunday be a day of rest devoted to Sol Invictus (The Undefeated Sun).

The first fully Christian emperors were Constantine's sons:Constantine II , Constantius II and Constans.

Answer 2

• The argument will be between Phillip the Arab (244-249) and Constantine (306-337)
• Constantine was (supposedly) the first Christian emperor of Rome.
• Constantine was the first Christian Roman emperor

The first emperor to claim he was Christian was Constantine the Great. He was the 57th emperor of the Roman Empire and reigned from 306 to 337.

Answer 3

Many will state that Constantine became the first Christian Emperor in the early 4th Century AD, though others will say he never truly converted from his pagan beliefs. Additionally, there are some writings (Eusebius) that may point to Philip the Arab as being the first baptized into the faith a century earlier, though this cannot be fully substantiated.
