Yes. The Scripture is complete as written; it does not need extra traditions or rules.
Traditions of the Church Christ founded are not man-made, and they do not contradict Scripture.
Proof please? Where does the tradition that priests are to be celibate come from Scripture? Just that one, for example...
That is not a Scriptural position. At all. It is a tradition of man. That means it is fallible. That does NOT mean ALL the Church's traditions and teachings are wrong, but it also means the Church itself is fallible.
That is your interpretation.
It is a tradition of man.
No, it is a voluntary vow taken by men who want to become priests.
