Your fathers did eat manna in the wilderness, and are dead.
All Commentaries on John 6:49 Go To John 6
Cyril of Alexandria
AD 444
They then who ate the manna (He says) are dead, not having received any participation of life therefrom (for it was not truly lifegiving, but rather taken as an aid against carnal hunger and in type of the true); but they who receive in themselves the Bread of Life, will have |408 immortality as their prize, wholly setting at nought corruption and its consequent evils, and will mount up unto boundless and unending length of Life in Christ. Nor will it at all damage our words on this subject that they who have been made partakers of Christ, need to taste bodily death on account of what is due to nature; for even though they falling into this end undergo the lot of humanity, yet, as Paul saith, they that shall live, live to God.
