This passage says the teachings and writings known to Timothy are sufficient

Correct, the oral teaching and the scripture are together sufficient to perfect the clergyman, exactly what the Catholic Church teaches.

Correct, the oral teaching and the scripture are together sufficient

At the time of Timothy; no more teaching and Scripture is required...

to perfect the clergyman

And where is that found? I see man of God, we are all men of God, we are all called to spread His Word. I do not see a restriction in that verse to clergy!

exactly what the Catholic Church teaches

Except the Catholic Church has added theology and teachings beyond that which existed for Timothy, and claims that it must be accepted as inerrant.
