What the sisters taught you when you were an 8 year old the Catholic Church still teaches today. You, however, obviously no longer accept this. Just as a matter of interest, how did it come about that you now reject this teaching? What influenced you to reject it?
Don't answer if you don't want to but as I have often stated before, I cannot comprehend how someone can reject core, Catholic doctrines (Original Sin and the subsequent Redemption) and still claim to be a member of the Church. No one yet has ever given me an explanation which I have been able to understand.
If God sent His only Son to His death merely to reform Judaism, then it all went horribly wrong, Judaism refused to be reformed. This makes the institution of the Church sound like plan B.
As I said feel under no obligation to reply.
