2 Thess 2:14-15
14 To this he called you through our gospel, so that you may obtain the glory of our Lord Jesus Christ. 15 So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.
Do you not think this is saying we must “hold firm” to the gospel in order to obtain the glory? does it not say that the oral traditions are equally important as the writings in reinforcing that firmness?
1 Cor 11:1-2
Be imitators of me, as I am of Christ.
2 I commend you because you remember me in everything and maintain the traditions even as I have delivered them to you."
Christ learned and transferred the traditions. why would Paul commend them, if it was not appropriate to keep the traditions, as this was how Christ was imitated? Can you tell me the important doctrines that this oral tradition contains?
James 1:21
21 Therefore put away all filthiness and rank growth of wickedness and receive with meekness the implanted word, which is able to save your souls. "
Actually Paul was directly taught by the Lord Himself.
In reality you are fighting a straw man here.
I believe most of the New Testament was written within 10 to 20 years of the resurrection.
No one denies that the Oral presentation of the Gospel existed before it was written down.
Certainly the verses that speak about tradition do not indicate in any way that this tradition was in any way a different message than what was written down. Why would it be?
All the tenets of the Faith are repeated many times over in different passages and yet some oral tradition, some extrabiblical doctrines somehow remained oral makes no sense.
Since important doctrine is repeated many times in many places in the scripture, whatever this oral tradition is, cannot be all that important.
The scripture cannot be twisted to make it say what you want.
