2 Peter 1:3His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness.
... does not support your point, because it does not say He has given us everything in writing
In fact, if you ignore what St. Paul said and reject Sacred Tradition --- the spoken words and example of the Apostles and the earliest communities they founded --- you're not getting "everything" He has given us.
1 Corinthians 11:2 "I praise you because you remember me in everything and hold fast to the traditions, just as I handed them on to you." And again...This Oral Tradition does not exclude or replace the Written Tradition (Scripture.) In fact, they strengthen each other at every point, since they have the same source.2 Thessalonians 2:15 "Therefore, brothers, stand firm and hold fast to the traditions that you were taught,either by an oral statement or by a letter of ours." And again...
2 Thessalonians 3:6 "We instruct you, brothers, in the name of Our Lord Jesus Christ, to shun any brother who conducts himself in a disorderly way and not according to the tradition they received from us."
Therefore, stand firm, hold fast, and conduct yourself according to this tradition, whether oral or written.
His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness.

Then WHY did your One True Church FAIL to teach the seven churches in Asia correctly?
Weren't the 'sacred traditions' not yet in place?
Show bus where in the WORD that Paul or Peter refer to tradition as *sacred tradition* and where they tell us to adhere to it.
Then give us the list of sacred tradition that has been passed down from the apostles themselves, how you know it came from them, and how you are sure that it has been faithfully passed down without change or corruption.
