“The old truth that Calvin preached, that Augustine preached, that Paul preached, is the truth that I must preach to-day, or else be false to my conscience and my God. I cannot shape the truth; I know of no such thing as paring off the rough edges of a doctrine. John Knox’s gospel is my gospel. That which thundered through Scotland must thunder through England again.”—C. H. Spurgeon, the great English Calvinist Baptist preacher of the 19th century
