John Chrysostom
Next the Apostle explains why they do not eat the Lord's Supper: "for each one hastens before others to eat his own food, so that one is hungry and another is drunk" (1 Cor 11:21).
Do you see how he proved that they chiefly shame themselves? They appropriate to themselves what belongs to the Lord. Therefore, before all else, they abase themselves, depriving their meal of the very thing that gives it its greatest dignity.
Why, and in what way? The Lord's Supper, that is, the Master's, ought to be common. What belongs to the master does not belong to this or that servant, but is common to all. It is the Lord's, he says, and therefore common.

If it belongs to your Master, as indeed it does, then you must not appropriate it to yourself. Since it belongs to the Lord and Master, you must offer it to all alike. It is the Lord's, yet you hinder it from being the Lord's by not allowing it to be common, but eating by yourself.
Therefore he adds: "for each one hastens before others." He did not say, "separates," but "hastens," covertly reproving them for excess and lack of self-control. This is also explained by what follows. After saying this, he continues: "so that one is hungry and another is drunk." Both want and excess show immoderation.
Here is a second fault, which also harms them. The first is that they dishonor their own supper. The second is that they become sated and drunk, and what is still worse, while the poor are hungry.
What ought to have been offered to all alike they consume alone. In this way they fall into satiety and drunkenness. Therefore he did not say, "one is hungry and another is filled," but "another is drunk."
Each of these deeds is itself worthy of condemnation. To get drunk, even without neglecting the poor, is criminal. To neglect the poor, even without getting drunk, is criminal. If both are joined together, consider how great the offense is.
