Eucharistic fast

Yahweh’s fast is “to divide bread for the hungry” (Isaiah 58:7). Then again, it’s to “give yourself to the hungry” (v. 10). Giving bread is a mode of self-gift.

Jesus keeps Yahweh’s Eucharistic fast.

Yahweh’s fast is to cover the naked and “not to hide from your own flesh” (v. 7). That could mean, “not hide from flesh that is like your flesh,” but it could be taken more strongly: “You are one-flesh with the poor, and his naked exposure is your own shame. Cover your neighbor as you would cover yourself.”

And again: Jesus doesn’t recoil from our shameful flesh but takes it as His own flesh, so that He can cover it with glory. Jesus keeps Yahweh’s incarnational fast.
