Salvation is not through the Catholic church. It's not through a organization but a person. The Catholic church did not die for me.
Peter, the guy you call your first pope, says this....
Acts 4:12 And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.
Jesus meets us where we are, not in a building where we go to meet Him.
1 Timothy 2:5-6 For there is one God, and there is one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all, which is the testimony given at the proper time.
It is by (not through) Jesus our Savior, Whom you know from the Catholic Church, or not know if you deny the truths of the Catholic Church.
