It's obvious to me, after looking at verses that use the word "tradition," that the Bible is speaking of practices (especially behavior) that have arisen in the religious community..
The bible rejects those practices that are of human origin.
It accepts those that have a solid Biblical basis or a basis in the life of Jesus or of the Apostles.
How do we hear from the Apostles and Jesus?
From their own words.
Where are those?
Scripture.
How beautiful on the mountain are the feet of those who bring Good News.
Are arguing with St. Paul?
2 Thessalonians 2:5
Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
