What will it avail thee to dispute profoundly of the Trinity, if thou be void of humility, and art thereby displeasing to the Trinity? Surely high words do not make a man holy and just; but a virtuous life maketh him dear to God.
I had rather feel compunction, than undersatnd the definition thereof. If thou didst know the whole Bible by heart, and the sayings of all the philosphers, what would all that profit thee without the love of God and without grace? Vanity of vanities and all is vanity, except to love God, and to serve him only.
