Charles H. Spurgeon on Psalms 15:5

The Puritanic divines are almost all of them against the taking of any interest upon money, and go to the length of saying that one penny per cent. per annum will shut a man out of heaven if persisted in. It appeared to me to be useless to quote opinions in which I cannot agree, especially as this would occupy space better employed. The demanding of excessive and grinding interest is a sin to be detested; the taking of the usual and current interest in a commercial country is not contrary to the law of love. The Jews were not engaged in commerce, and to lend money even at the lowest interest to their fellow farmers in times of poverty would have been usurious; but they might lend to strangers, who would usually be occupied in commerce, because in the commercial world, money is a fruitful thing, and the lender has a right to a part of its products; a loan to enable a non-trader to live over a season of want is quite another matter.
