So then I got put in catholic school, and without knowing what sex was, began to ask the church if Mary had baby Jesus, through God, so God is the father, why wasn’t Peter pissed that his wife was having a baby with another man?

They evidently went kinda easy on the religious teachings?

I’m not a religious man and despite monotheism as a phenomenon and think it’s bad for mankind, but even I know Mary was married to Joseph. Peter was one of Jesus’s apostles and the first pope.
