Only He who made man makes man happy.

A Christian man is on his guard with respect to those who philosophize according to the elements of this world, not according to God, by Whom the world itself was made; for he is warned by the precept of the apostle and faithfully hears what has been said, 'Beware that no one deceive you through philosophy and vain deceit, according to the elements of the world'

What then, is correctness of speech but the maintenance of the practice of others, as established by the authority of ancient speakers? But the weaker men are, the more they are troubled by such matters. Their weakness stems from a desire to appear learned, not with a knowledge of things, by which we are edified, but with a knowledge of signs, by which it is difficult not to be puffed up in some way; even a knowledge of things often makes people boastful, unless their necks are held down by the Lord's yoke.

We who preach and write, do so in a manner different from which the Scriptures have been written. We write while we make progress.We learn something new every day.

But I would be more angry with the one who praises me and takes what I have written for Gospel truth than I would be with the one who criticizes me unfairly.
