"The Tradition of the Church somewhere comes back to an arbitrary decision..."
If that's what Tradition is, I have no desire for it.
Me neither, in light of this:
Mark 7:5 The Pharisees and the scribes asked Him, "Why do Your disciples not walk according to the tradition of the elders, but eat their bread with impure hands?" 6 And He said to them, "Rightly did Isaiah prophesy of you hypocrites, as it is written: `THIS PEOPLE HONORS ME WITH THEIR LIPS, BUT THEIR HEART IS FAR AWAY FROM ME. 7 `BUT IN VAIN DO THEY WORSHIP ME, TEACHING AS DOCTRINES THE PRECEPTS OF MEN.' 8 "Neglecting the commandment of God, you hold to the tradition of men." 9 He was also saying to them, "You are experts at setting aside the commandment of God in order to keep your tradition."
