144 more than a century earlier ( 1059) for denying it. The mediæval schoolmen were the first to attempt metaphysical explanations of the doctrine. But the essential idea appears full blown as early as the fourth century, and to nobody is the formulation of it more distinctly attributable than to Gregory of Nyssa. This daring and original Church Father writes, "The body of Christ was transmuted to the flesh of God by the indwelling of God the Word. I do well then in believing that now also the bread of God the Word, when consecrated, is being transmuted into the body of God the Word."

For as when the destructive agent was mingled with the sound (body), all that it was mingled with was made worthless with it, so the immortal body also, having come to be in him that has received it, transmuted the whole also into its own nature.

Thus the eating and drinking of the Eucharistic elements by the Christian is supposed to secure for his body what the Egyptian aimed at by the art of embalming, what the
