I am not familiar with what you posted nor am I Catholic but a coworker of mine is Catholic and he is atheist and he was complaining that technically Birth Control is still against the teachings of the Church. (which they naturally ignore)
Its a grand irony that a church that frowns of married couples using birth control has had in the past so much of a problem with Church related child molestation.
Most or all of which is Man on Boy.
I will not got in to a dissertation of Babylonian priests as there are folks that do way better than me laying it out. They followed the worldwide wins throughout history, For instance, Egypt, to Assyria, to Persia, to Greece to Rome and that’s where they are to this day, so far. I assume they’ll head off to Jerusalem soon. There are a couple interesting books that follow this exodus of the priests but I’d rather email if interested. I’m not up for a debate today.
‘a coworker of mine is Catholic and he is atheist’
Why bother? An insurance policy?
