What is the heresy of [the Roman Catholic Church], but the addition of something to the perfect merits of Jesus Christ, the bringing in of the works of the flesh, to assist in our justification? And what is the heresy of [Free-will Religion] but the addition of something to the work of the Redeemer? Every heresy, if brought to the touchstone [that is Christ and His doctrine], will discover itself here. I have my own private opinion that there is no such thing as preaching Christ and Him crucified, unless we preach what nowadays is called Calvinism. It is a nickname to call it Calvinism; Calvinism is the gospel, and nothing else.
