The failure of the Bishops to clearly ex communicate pro abortion Catholic politicians has done grievous harm to the Church and the well being of the faithful. An unpleasant but absolute responsibility of the hierarchy throughout Church history is to ex communicate harmful heretics.
It has to do with money.
My grandmother, the second daughter in a family of 22 children, was given to the Roman Catholic church at age 3. Her older sister had been promised in marriage to a family friend but died at age 16, so my grandmother was taken from the convent, cleaned up, and married off to the family friend. He wasn’t pleased with his bride who hadn’t the beautiful dark-haired, blue-eyed Irish loveliness of her older sister but rather the orange-haired, pudgy-faced look of her Scottish ancestors. Thankfully she could cook (it had, after all, been a French convent) and her husband put her to work in his restaurants.
When she became pregnant he beat her because she couldn’t work due to her condition. She miscarried. When she became pregnant again, she fled her husband and sought an annulment.
He headed off that action by donating large amounts of money to the church.
Heretics have a point when they say the Roman Catholic church is rotten, but it isn’t the church - it is the hierarchy who are only too human and rotten.
