I am not trying to impose my beliefs on you. There is only ONE TRUTH. It is found in scripture. Anytime you have men proclaiming new truths outside of scripture, it creates a big problem becuase all men are fallible and sinful. I want to encourage you to read scripture. SCRIPTURE CAN BE TRUSTED - JESUS SAYS SO. Rest on the solid truths of scripture. If your beliefs are false or contradict what scripture says, would you not want to know this? Why not be a seeker of truth? You don't have to believe what others tell you - believe what God tells you through His Word.
The symbolism of that door is very meaningful if you are into doors and all that. Jesus referred to himself as a door. Metaphorically, of course. No doubt people walked through that door because it was part of the jubilee celebration but were clueless about what the significance of it was.
Whatever. I'm not going to fret about scripture any more today.
When you want to win a friend, it is better not to fire an opening shot trashing something they believe in. That is what makes catholics so defensive.
I wish you the best.
