spiritual, and yet flesh shall not be changed into spirit._
The bodies of the righteous, then, such as they shall be in the
resurrection, shall need neither any fruit to preserve them from
dying of disease or the wasting decay of old age, nor any other
physical nourishment to allay the cravings of hunger or of thirst;
for they shall be invested with so sure and every way inviolable an
immortality, that they shall not eat save when they choose, nor be
under the necessity of eating, while they enjoy the power of doing
so. For so also was it with the angels who presented themselves to
the eye and touch of men, not because they could do no otherwise,
but because they were able and desirous to suit themselves to men
by a kind of manhood ministry. For neither are we to suppose, when
men receive them as guests, that the angels eat only in appearance,
though to any who did not know them to be angels they might seem
to eat from the same necessity as ourselves. So these words spoken
in the Book of Tobit, "You saw me eat, but you saw it but in
vision;"[607] that is, you thought I took food as you do for the
sake of refreshing my body. But if in the case of the angels another
opinion seems more capable of defence, certainly our faith leaves
no room to doubt regarding our Lord Himself, that even after His
resurrection, and when now in spiritual but yet real flesh, He ate
and drank with His disciples; for not the power, but the need, of
eating and drinking is taken from these bodies. And so they will be
spiritual, not because they shall cease to be bodies, but because
they shall subsist by the quickening spirit.
