But what does he (Paul) wish them to learn? That no one be puffed up for his own
teacher against another, that is, that they be not lifted up with pride on account of
their teachers, and do not abuse their names for the purpose of forming parties, and
rending the Church asunder. Observe, too, that pride or haughtiness is the cause and
commencement of all contentions, when every one, assuming to himself more than he is
entitled to do, is eager to have others in subjection to him.
