Second question: What web site did you get this information from? I have news for you. It's wrong!
Third question: where does Matthew 15:1-14 refer to the Catholic Church. And I'll give you the answer: Nowhere! In fact it is a traditional Protestant interpretation to assume that when Jesus condemns the Pharisees He is somehow also condemning the Christian Church. To call our traditions "traditions of men" is (a)to condemn the Bible, since it is a tradition of ours a thing we "handed across" the generations, and (b) to assume what you set out to prove. And consequently, it may impress your friends, but it is a circular argument to us, and therefore not persuasive. You guys argue like Muslims.
In fact, you guys have your traditions and you guys depend on your traditional interpretations of Scripture. But we do not think we are Pharisees. The Pharisees were a faction of Jews who rejected Jesus. That does not describe us.
The interesting question is why you think it does.
