Faith without works.
As far as sola Scriptura, see Jesus' words in Mark 7:1-15. Jesus is quite explicit: tradition and non-Biblical teachings are secondary to the Bible - the word of God.
That is YOUR interpretation.
Christ is condemning human traditions that contradict Scripture.
Traditions of the Church Christ founded are not man-made, and they do not contradict Scripture.
You do not need anything beyond its words, or you run the risk of being the hypocritical pharisees that Jesus spoke against.
Such is YOUR interpretation.
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.
