Then one day when I was on retreat and sitting before the Blessed Sacrament, the opposite (and to my more beautiful) side of the mystery suddenly came to me: instead of reflecting on how the bread could become the Son of God, I began to wonder at how the glorious and almighty God was willing to become our bread.
Later on I found this same meditation in Francis's Letter to the Entire Order:
O sublime humility
O humble sublimity
That the Lord of the universe,
God and the Son of God,
so humbles Himself that for our salvation
he hides Himself under the little form of bread!
