I completely agree with that. Look, I'm Catholic, and constantly debate, argue with, and discuss with Protestants, and I almost always win the arguments. Several times they even ADMIT I won the arguments and still go one beliving whatever it is they believe.
I certainly don't blindly take for granted the Bible. I have done research and it is satisfactory enough for me to believe that the Gospels are valid historically. From there, I arrive at the Catholic Church.
I would ask though: Just suppose you ever DID think begin to think the Gospels were historically valid. Would you then believe in Christianity? Or would you not even if someone adequately proved their validity?
I am just curious about that. I don't want to get into an argument about it.
