Answer:
Christianity advanced from a persecuted belief to the common major religion in the Roman Empire. Constantine's guide for Christianity continued slowly in its construction, and distant from an expected appearance.
Explanation:

Constantine’s assistance for Christianity was lazy in its development, and far from an expected appearance.
