Jack is very clear and mostly right. The Catholic Church is mistaken in insisting that others are in “doctrinal error” when we disagree with their forbidding to marry and in calling priests “father, “ in declaring that Mary was a virgin for her whole life, and in condemning trur contraception.
You never did explain why contraception is expressly forbidden by the law on levitate marriage, but levitate marriage is not commanded by the same scripture.
That should be “levirate” marrige.
Sincerely, why dispute over these things? You only divide and cause stumbling blocks for others.
