John Chrysostom

Admirable! how great is the wisdom of Paul! Observe, he doth not put everything into his Epistles, but only things necessary and urgent. In the first place, being desirous of not drawing them out to a length; and secondly, to make his messenger more respected, by his having also somewhat to relate; thirdly, showing his own affection towards him; for he would not else have entrusted these communications to him. Then, there were things which ought not to be declared in writing. "The beloved brother," he saith. If beloved, he knew all, and he concealed nothing from him. "And faithful minister and fellow-servant in the Lord." If "faithful," he will speak no falsehood; if "a fellow-servant," he hath shared his trials, so that he has brought together from all sides the grounds of trustworthiness.
