I am the bread of life.

John Calvin Reformed

48. I am the bread of life Besides what he formerly said, that he is the life-giving bread, by which our souls are nourished, in order to explain it more fully, he likewise repeats the contrast between this bread and the ancient manna, together with a comparison of the men.

John Gill Reformed Baptist

This is the bread which cometh down from heaven,.... Namely, that of which he had spoken Joh 6:32, meaning himself: that a man may eat thereof, and not die; for this heavenly bread is soul quickening, soul strengthening, and soul satisfying food; nor can there be any want where this is: eating of it is not to be understood corporeally, as these Capernaites took it...

Geneva Bible Notes Reformed

I am that bread of life. (10) The true use of sacraments is to ascend from them to the thing itself, that is, to Christ: and by the partaking of him alone we get everlasting life.
