The Bible clearly disagrees with you, and commands obedience both to sacred tradition (2 Thess 2:15) and church authority (Heb 13:7-8, 13:17).
Get back to us when you actually start obeying your "only source" consistently, instead of picking and choosing which parts you want to obey.
It's a pity you must take verses out of context to follow sinners that steer you wrong.
2Tim.3:16
[16] All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
As for your traditions and philosophers:
Col.2:8
[8] Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ
Unfortunately your "traditions" and "philosophers" don't agree with or follow Christ. It is precisely what God warns AGAINST.
1Pet.1:18
[18] Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers;
And you follow what is advised AGAINST.
