I have no tradition that contradicts the Bible, which I’ve quoted several times and you have ignored. The Pharisees were exactly the same way, uphold the tradition and ignore the scripture.
If there is a lack of knowledge, it is your inability to explain the reason why scripture is to be set aside.
Catholic tradition does not contradict the Bible. How did people learn about Christ when there was no Bible in his day? By Holy Tradition — people talking with one another face to face.
I don’t see why non-Catholics can’t understand that.
As I said above — from the people who knew Jesus....and then the people who knew those who knew Jesus. And so it continued because there was no written word until 50 AD.
