Your answer that the tradition came before Scripture told me everything I needed to know. Because what we know about the Old and New Testaments are recorded in Scripture; any way tradition could have arrived at would have to have been through the Scriptures since the Apostles are long gone.
Therefore to arrive at any tradition that is not based upon the Scriptures would be to conjure them or make them up. This is the danger, for if they can be made up right now then the authority is in the hands of fallible men.
The attack upon Scripture is a sophistry attack and an attempt to undermine the Scriptures of the Old and New Testaments since it claims authority outside the Scriptures that God has clearly given. Indeed, isn't that is what Serpent started with "Has indeed God said?" - the M.O. to question the Authority of God and His Word craftily.
So I place the putting of tradition above God's Word and splitting God's Word from the Bible as such .
Turn away from such craftiness as soon as you possibly can. For any such trust outside the Scriptures is sinking sand. Trust upon Christ Himself, for He is the Solid Rock alone.
Further discussion regarding tradition will be fruitless, for you can do nothing apart from Christ.
