I was reading your replies to comments, and noted your “journey of deconversion” statement. My question to you is; how can you walk away from something you never knew? The very core belief of Christianity, the very foundation of it, is that you must accept Our Lord, Jesus Christ in order to be saved. Surely anyone who is/was in the least bit familiar with the Faith knows this. Salvation is not given, or rather handed out, especially to those that reject him. If this were true, if we were all saved regardless if we believed in Christ or not, there would be no purpose for the Second Coming of Christ (Our Judgement). Not knowing Him IS rejecting Him, if you are not with Him you are against Him. Yes, I have read your OP and how you seem dissatisfied with the 200+ responses.
Jesus died through love of us, so that we MIGHT live.
Technically, your “very Catholic father” is committing the sin of Omission by not telling you the truth, or by refusing to see the truth for himself.
Maybe this verse from the Book of Matthew will answer your question
Matthew 24:13-The one who perseveres to the end will be saved.
