Constantine embraces Christianity — no good comes of it.

Constantine delayed his actual baptism until he was on his deathbed — a practice followed by many in his time, who wanted to continue sinning as long as possible before taking advantage of the one-time-only guaranteed means of forgiveness for past sins.

The bishops railed against this practice but couldn’t find a theological rationale or a workable process for prohibiting it.
