Raised Catholic, currently atheist:
That’s not really what is said in the bible about forgiveness - it’s very clearly stated that god knows your heart and there is no forgiveness without true penance. That’s not “say 5 hail mary’s and 3 lord’s prayer and you’re all good”, that’s a run-off effect of the middle-ages “indulgences”, where someone could be “forgiven” their sins for a payment to the church.
Actual forgiveness as described several times in the bible explicitly requires the confessor to be truly sorry for their sin (contrition), and a real commitment to do better in the future. This is a fairly concise summary of what the bible says about contrition, confession and forgiveness: https://biblehub.com/topical/c/contrition.htm
TL;DR - There is no forgiveness if you are not truly sorry and if you don’t do your best to be better.
Not sure how you got that from my comment, or why you decided to be snarky in your reply, but whatever. My statement is that even in their dogma, they’re doing it wrong and if any of it were true, they’d be going to hell regardless.
