Unoriginal Calvin

"Hence, whoever may come after [Paul], can in no other way serve the Lord with a good conscience, or be listened to as ministers of Christ, than by studying to make their doctrine correspond with his, and retain the foundation which he has laid. Hence we infer, that those are not faithful workmen for building up the Church, but on the contrary are scatterers of it, (Matt. 12:30,) who succeed faithful ministers, but do not make it their aim to conform themselves to their doctrine, and carry forward what has been well commenced, so as to make it quite manifest that they are attempting no new work"

John Calvin
