In the first place, it must be understood that all the apostles present one and the same doctrine; and it is not correct to speak of four evangelists and four Gospels for all which the apostles wrote is not Gospel. But gospel means nothing but a proclamation and heralding of the grace and mercy of god through Jesus Christ, merited and procured through his death. And it is not properly that which is contained in books, and is comprehended in the letter, but rather an oral proclamation and living word, and a voice which echoes through the whole world, and a voice which echoes through the whole world, and is publicly uttered that it may universally be heard. Neither is it a book of laws, containing in itself many excellent doctrines, as has hitherto been held. For it does not bid us do works hereby we may become righteous, but proclaims to us the grace of God, bestowed freely, and apart from any merit of out own; and it tells how Christ has taken our place, and rendered satisfaction for our sins, and concealed them and by His own works justified and saves us.
