From the early Church Fathers to now.
“And the house of Israel called the name thereof Manna: and it was like coriander seed white, and the taste thereof like to flour with honey.”
“The Word of God becomes all these things to each and every one according as the capacity or the desire of the participant requires. In just the same way the manna also, although it was one food, yielded its flavor to each person after his desire. So he does not offer himself only as bread to those who hunger and as wine to those who thirst, but he presents himself also as fragrant apples to those who crave delights.”
“And moreover when they ate it formerly, its taste was changed into that of all kinds of meats in their mouth, and it is well known that it also took the place of flesh unto them, for it is written, "It was like honey comb, and its taste was as if it had been kneaded in oil." And although it was changed into all these varieties of food the eaters thereof were not condemned thereby, for it was a gift of Grace, and not that which their lust had demanded.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
