But our hearts are more firmly grounded when we reflect that we are captivated with admiration for Scripture more by grandeur of subjects than by grace of language. For it was also not without God’s extraordinary providence that the sublime mysteries of the Kingdom of Heaven came to be expressed largely in mean and lowly words, lest, if they had been adorned with more shining eloquence, the impious would scoffingly have claimed that its power is in the realm of eloquence alone. Now since such uncultivated and almost rude simplicity inspires greater reverence for itself than any eloquence, what ought one to conclude except that the force of the truth of Sacred Scripture is manifestly too powerful to need the art of words? Therefore the apostle rightly contends that the faith of the Corinthians was founded “upon God’s power, not upon human wisdom” [1 Cor. 2:5 p.] because his own preaching among them commended itself “not in persuasive words of human wisdom but in demonstration of the Spirit and of might” [ch. 2:4 p.]. For truth is cleared of all doubt when, not sustained by external props, it serves as its own support.
