2 So, then, not being in doubt as to your faith, but anxiously considering the risk, and sure of a kindly consideration, I am replying in this document to the assertions of the Memorial, making this sole request, that you will not expect elegance of language but the force of facts. For, as the divine Scripture teaches, the tongue of wise and studious men is golden, which, gifted with glittering words and shining with the brilliancy of splendid utterance as if of some rich colour, captivates the eyes of the mind with the appearance of beauty and dazzles with the sight. But this gold, if you consider it carefully, is of value outwardly but within is base metal. Ponder well, I pray you, and examine the sect of the heathen, their utterances, sound, weighty, and grand, but defend what is without capacity for truth. They speak of God and worship idols.
