“What doth it profit thee to enter into deep discussion concerning the Holy Trinity, if thou lack humility, and be thus displeasing to the Trinity? For verily it is not deep words that make a man holy and upright; it is a good life which maketh a man dear to God. I had rather feel contrition than be skillful in the definition thereof. If thou knewest the whole Bible, and the sayings of all the philosophers, what should all this profit thee without the love and grace of God? Vanity of vanities, all is vanity, save to love God, and Him only to serve. That is the highest wisdom, to cast the world behind us, and to reach forward to the heavenly kingdom.”
