Quite a good treatise on Bible reading. I do wish Rome would apply such an impartial and encompassing respect for scripture to a good scrutiny of Her traditions.
Tradition means the Bible handed down orally from person to person. Some of it is in the Bible.
Some of it is not. That is what Holy Tradition is.
Or were you talking about Catholic customs and symbols such as ashes, palms, crucifixes, holy water, vestments, etc?
