The
body of Christ is signified and represented by bread; he had said formerly (John
6:35), "I am the bread of life," upon which metaphor this sacrament is built. As
the life of the body is supported by bread, which is therefore put for all
bodily nourishment, so the life of the soul is supported and maintained by
Christ's mediation - Matthew Henry
"And
said, take, eat, this is my body"; In Luke it is added, "which is given for you"
(Luke 22:19); that is, unto death, as a sacrifice for sin, and by the Apostle
Paul, in 1 Corinthians 11:24, "which is broken for you"; as that bread then was,
and so expressive of his wounds, bruises, sufferings, and death, for them. Now
when he says, "this is my body", he cannot mean, that that bread was his real
body; or that it was changed and converted into the very substance of his body;
but that it was an emblem and representation of his body, which was just ready
to be offered up, once for all: in like manner, as the Jews in the eating of
their passover used to say of the unleavened bread. - John Gill
In
each of our lives Jesus comes as the Bread of Life -- to be eaten, to be
consumed by us. This is how He loves us. Then Jesus comes in our human life as
the hungry one, the other, hoping to be fed with the Bread of our life, our
hearts by loving, and our hands by serving. In loving and serving, we prove that
we have been created in the likeness of God, for God is Love and when we love we
are like God. This is what Jesus meant when He said, "Be perfect as your Father
in heaven is perfect. - Mother Theresa
Apply
in the Sacrament what is true in the person of Christ. In order that the Godhead
dwell in Him, it is not necessary that the human nature be transubstantiated and
the Godhead be contained under the accidents, but since both natures are present
in their entirety, it is truly said: This man is God, and, This God is man. Even
though philosophy does not grasp this, faith does grasp it; and the authority of
the Word of God is greater than the grasp of our intellect. Just so in the
Sacrament. In order that the real body and the real blood may be in the
Sacrament, it is not necessary that the bread and wine be transubstantiated and
Christ be contained under their accidents; but both remain there together, and
it is truly said: This bread is My body; This wine is My blood. - Martin
Luther
If
Christ did not want to dismiss the Jews without food in the desert for fear that
they would collapse on the way, it was to teach us that it is dangerous to try
to get to heaven without the Bread of Heaven. - Jerome
On
the altar you are looking at the same thing as you saw there last night. You
have not heard, however, what this is, what it signifies, or about the greatness
of the reality of which it is a sacrament. Your eyes are looking at bread and
cup. This is the evidence before your physical sight. But your faith must be
instructed concerning it - this bread being Christ's Body and the cup containing
His Blood. Though perhaps these words may be enough to initiate faith, faith
must be further instructed in accordance with the Prophet's words: 'Believe that
you may understand' ( Isaiah 7:9). - Augustine of Hippo
