Do you even know the context of the story you quoted? The woman was going to be stoned. The man she was taken in adultery w had evidently been let off the hook, but the woman’s accusers told Jesus that according to the law she should be stoned. To suggest that calling a spade a spade where Calista’s adultery is concerned is concomitantly calling for her to be stoned is just vile. Shame on you.
Yep. Pretty sure that all Jesus meant was “I’m not going to kill you for being an adultress.” It is well known that Jesus held grudges, blamed people for their past failings despite repentance, etc.
Christians are always people who have led completely pure lives, like St. Augustine.
If Calista confessed her sins, did pennance, and amended her life - that’s the end of it according to her faith.
