I’ve always thought of the bread and water of the sacrament–the body and blood of Jesus–as emblems of his death only. That makes sense–the ordinance is to commemorate the Atonement.
But lately I’ve also been focusing on how it could direct us to his life, as well as his death.
The prayer on the water says, “the blood of thy Son, which was shed for them” (D&C 20:79), that second part explicitly directing us to think of Lord’s infinitely painful sacrifice that last night and day of his life.
The prayer on the bread, however, only mentions “the body of thy Son,” with no added description like there is on the water.
Indeed, the first two of the three Biblical synoptic gospels (John does’t mention the Last Supper), inspires this: both mention the body of Christ, without any further explanation, but then also mention the blood of Christ, with the overt follow-up about it being shed as a sacrifice for us:
26 ¶And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body.
27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
