Corruption spares no one individually. You are comparing human tradition with Sacred Tradition.
In my experience, and the church's as well (IMHO), the non-canonized writings of men tend to obscure, rather than make clearer, the very word of God
Sacred Tradition is not "non-canonized writings." You seem to refuse to acknowledge that the Church Fathers developed theology, and decided what is to be canonized based on their understanidng of the faith, which helped them establish orthodoxy and catholicity, as well as which of the written texts and gospels are to be canonized as the Bible based on unwritten, Sacred Tradition, the oral Teachings of Jesus Christ.
I would not call that "obscuring" the Word of God.

So ... is it your claim that the scriptures are 'of men' or ... 'of God' ?
