Twisting, ever twisting ... Syncro nor any other poster has stated that Mary sinned against Joseph. But we understand how the confused mind of a catholic reads these posts with a tail twist.
I’m not Twisting I’m the one anchored to the Truth nit some novel protestant conceptions for fighting against the reality that Mary was ever virgen such as your weird gamete and sex arguments. Disgusting.
Anyway I read someplace that all sins are against God, not individuals.
If you don’t obey God, you are sinning.
That’s why I insist that Mary did not sin and joined Joseph for...well...conjugal stuff. (Some posters go bonkers if you say “sex”)
Which of course is how they had more children after Jesus was born.
