Paul commands: 'Therefore, brethren, stand fast and hold the Traditions which you have been taught, whether by word or by our letter.' From this it is clear that they did not hand down everything by letter, but there is much also that was not written. Like that which was written, the unwritten too is worthy of belief. So let us regard the Tradition of the Church also as worthy of belief. Is it a Tradition? Seek no further.
Saint John ChrysostomIf you say, "Would there were no wine" because of the drunkards, then you must say, going on by degrees, "Would there were no steel," because of the murderers, "Would there were no night," because of the thieves, "Would there were no light," because of the informers, and "Would there were no women," because of adultery.
Saint John Chrysostom
