what did constantine do that helped spread christianity? established an official theology for the new faith outlawed polytheistic religions in the empire made christianity a legally recognized faith appointed the bishop of rome as the new pope
Answer
Brief Explanations:
Constantine issued the Edict of Milan in 313 AD, which made Christianity a legally - recognized faith in the Roman Empire. This removed the persecution that had hindered its spread and allowed it to grow more freely. He did not establish an official theology (that was more the work of church councils), did not outlaw polytheistic religions immediately, and did not appoint the bishop of Rome as pope in the way described.
Answer:
made Christianity a legally recognized faith
