Hi Jlove,
What to do with parents? Short answer, 'Love 'em".
No where in the Bible does it say to convert anyone. There is a good reason for this as only God knows the heart of a person and therefore can lead conversion. Another reason, Who says only Catholics are going to Heaven? Jesus says,“Do you think My Jews don’t go to Heaven, if their hearts are right? They do not worship Me, but they worship My Father and I am one with The Father, so of course they go to Heaven if their hearts are right. And what of my Protestants? Do you not think they go to Heaven if their hearts are right? Of course they do! Do not think that it is the label on the outside that merits Heaven. It is what is on the inside, in the heart.” Salvation comes to the world through the Catholic Church and salvation is to be shared with all peoples to the extent that they permit it. Do not force feed anyone, not even your parents. Jesus tells us that people can be driven from the Truth with nothing but the Truth. So just love them and share as you can your new found faith. If Jesus found you do you not think He will find His other sheep? Do not judge, just love one another and say to yourself, as St Michael the Archangel said to Satan,“I will leave it to My Father in Heaven to correct you.”
