To answer the OP ( I haven’t finished reading this thread, but just had to interrupt), my husband thinks you are right. Some people who leave the Church have such deep turmoil (after all they are leaving what they thought was the key to their salvation) that it is so hard not to be bitter, or angry or broken-hearted about it.
Here’s my mother-in-law’s story. She was raised Italian-American in a very Catholic family. After she married and had a few kids, she wanted to get her tubes tied. She said her priest told her she would “go to hell.” So she left the church 30 something years ago and never looked back. She hates the Church and doesn’t miss a chance to bash it when she can (just shows me the inner turmoil inside.) She is very liberal and very pro-abortion now. Her husband goes to Mass without her (he’s not really devout, but he does still go to Mass). My poor husband is so worried for her salvation. He wanted me to ask you guys, what can he do, if anything, besides pray for her. Any books to recommend? She is a voratious reader.
One thing he said to her which was awesome, I thought, was “Mom, I realize that priest hurt you. He shouldn’t have. But you cannot throw out the Church because of one bad or even 100 bad priests. If someone lies to me, should I now not believe in the truth? If someone cheats me, do I now disregard honesty?”
There are a lot of ex-Catholics here who I think want a reason to come back, or else need to justify to themselves that they were right to leave. I ran into an ex-Catholic in a bookstore one evening, and she literally screamed at me (

) for 40 minutes about how terrible the Church is, how the Pope isn’t infallble, about how dumb my Miraculous Medal is, how I shouldn’t depend on Mary for graces, how the Bible is the only teaching I need to follow. My husband was so embarrassed for her, he wouldn’t come to bail me out. I really was just jaw-dropped, standing there getting pummeled. When she finally paused in her tirade, I suggested to her that she read some Church history, and told her that I definitely sensed the inner turmoil in her. I told her I would pray for that anguish to leave her; curiously, she said nothing. I felt I had hit the nail on the head.
Please pray for the fallen away who have bitterness or sadness. They need so much healing ! And pray for those who do not do such a great job for Holy Mother Church.
Blessings,
