Classic example of Jesus and...
Adding to G-d’s word what he ha snot said is a very dangerous thing.
Christ is sufficient, that is clearly stated over and over in the bible.
Our Lord is big enough that his death alone was sufficient, He does not need a ritualistic tradition to confer his grace.
Why did God directly institute "ritualistic traditions" in the Old Covenant like the Passover Seder, then? Was he setting a bad example for us? Did he change his mind in the intervening 1500 years?
