That's more inaccuracy, to be honest. See, ALL early Xians tried to only baptise on the death bed. It doesn't mean that's when they converted. And that includes Constantine.
In OUR times, yeah, getting baptized is the beginning. If you sin after that, well, just see a priest and get more forgiveness.
For them it was a one-off get all your sins forgiven card. Key words: one-off. If you sinned after that, it meant you hadn't REALLY accepted Jesus and you're going straight to hell. No more forgiveness, no second chances.
So they took this to the logical conclusion: if you only get one shot at having all your sins forgiven, then just get baptized on your deathbed. And Constantine just fits that pattern, nothing more.
As for Nicaea, I think the wrong assumption that some people make is assuming it worked by modern (or even ancient) rule-of-law logic. You know, where you first need to debate what is legal and what isn't, and then legislate based on that. E.g., you first need to define what jaywalking is, before you judge whether someone is guilty of that.
So you'd ASSUME that they couldn't possibly be against heresy before having a conference to discuss and debate and decide and come up with a definition of exactly what counts as orthodoxy and what counts as heresy. And then judge the actual cases based on that definition. You'd think it would work that way, wouldn't you?
But these were some of the most deranged Jesus fanboys, even by fanboy standard. They worked by
Fan Dumb logic, with just a pinch of
Insane Troll Logic thrown in for good measure.
The fact is, even after Nicaea, they wouldn't actually have a legal definition of heresy until the year 380. That's more than half a century after Nicaea. In fact, it didn't even happen under Constantine. It wouldn't even be until ANOTHER emperor that it occurred to someone to even have a clear and workable definition. In the meantime they persecuted heretics ANYWAY, not even pausing to notice that they lack even a definition for it.
