LOL, I’m sorry, this is not funny, but I read your situation and it looks so much like mine that I cannot help but laugh, not in a funny way, but in a “welcome to the club” kinda way!!!
Fortunately many people are finding themselves in this kind of situation lately or so I hear. Which is good, it means many of us are finding our way back to the Catholic Church.
Okay so to address a few of the many different topics you brought up which someone would need many books to cover in total…
First, pray, pray for them, but also realize that we know from the mystics and Saints of the Church that many Protestants are in heaven, and while you don’t have to be Catholic to get into heaven once you’re there you are part of the Catholic Church! So they will end up converting eventually… (lol, I used that line on my father, I did not get the laugh I expected but I still thought it funny and clever).
Second, the divorce and abortion does not really matter since the way they were brought up it is not a sin. Remember, to commit a mortal sin you must have full knowledge that what you are doing is sinful. While they may have only had a partial knowledge (which only God can judge and really knows) it would clear them of a mortal sin making it venial and thus still allowing for God’s Divine Mercy to save them.
Third, look up and read about God the Father coming and speaking to one of our religious sisters. I cannot remember the name of the book but anyway, basically God says anyone that truly looks to Him and calls Him “Father” He will eventually grant eternal rest. Protestants absolutely fall into that “category” if you will. It’s the only time in history where we see God the Father coming to the Church and speaking directly to us.
Also read about Fatima, offer up this suffering that you must endure and is obviously very painful, offer it up to God, it will help save and convert many people.
Read about Our Lady of Good Success, she promises us that soon (after the 20th century) there will be a mass conversion back to the Catholic Church. Read these and many things, while on the surface they seem distressing they really are about good news!
Finally if you are not in a position to have healthy debates with them about the differences of our religion and theirs then don’t. But remember what Jesus says, that He did not come to bring peace, but divisions, that son will go against father and daughter and against mother and so on…while you don’t have to deny your family, now that you know the truth and the way you must stay strong and keep to the path that obviously God lead you to.
Please feel free to contact me privately if you need any help, have any questions or if anything comes up, I’m always here for everyone, especially a fellow convert!!!
