The Pugilist: Supernatural

Men have always and everywhere judged that a supernatural man, doing a supernatural work, must needs have sprung from a supernatural source. If there had been nothing extraordinary in the coming of the Savior into the world, a discordant note would have been struck at this point in the “heterosoteric” Christianity of the New Testament, which would have thrown it in all its elements out of tune. To it, it would have been unnatural if the birth of the Savior had been natural, just because it itself in none of its elements is natural, but is everywhere and through all its structure, not, indeed, unnatural or contra-natural, but distinctively supernatural. – B.B. Warfield in The Supernatural Birth of Jesus
