What time of day should the church celebrate the Lord's Supper?

Why is the Lord’s Supper kept on Lord’s Day morning when according to the Book it was always celebrated in the evening?

The hour for the observance of the Passover was definitely laid down by Jehovah. It was to be “in the evening” ( Exodus12:6), but no such order is given for the celebration of the Supper. No doubt, our Lord instituted His supper at the close of the paschal feast, but He neither enforces the time on the Apostle, nor does Paul in 1 Corinthians 11: . When he reminds the Corinthian saints that it was “the same night that He was betrayed” that our Lord took the bread, etc., the emphasis seems clearly on the proximity to His betrayal, rather than to the fact that it was eventide. In other words, it was not the time of day, but the time in relation to what was to follow.

Christianity is not a system worked on a time-table, like Judaism—”Ye observe days and months and times and years” (Galatians 4:10). Certain ceremonialists are intensely occupied with the time of the observance, the colour, etc., of the bread (it must not be white, and it must be unleavened!), the kind of wine (it must be “unfermented”). But this verges at best on a mechanical imitation. One wonders why these good folk do not insist on reclining on couches, as no doubt our Lord and His disciples did, or at any rate observing the Lord’s supper on the very day He instituted it. Nothing we can make in the way of bread or wine could adequately represent the holiness or purity of Christ. To interpret the leaven of the Old Testament by literal leaven is not an intelligent understanding of the types. An Old Testament type refers to a New Testament reality. No, we are not to examine the table to see if there be any leaven or “ferment” thereon, but ourselves, lest there be any old leaven of wickedness in us, or malice or untruth.

The early disciples may always have broken bread in the evening, but if so, it was for convenience sake (as they were working all Lord’s Day, as all other days), and that is quite have never heard that any teaching is supposed to depend on evening communion. But how the legal mind of man loves to enforce its enactments on all! “Stand fast in the liberty wherewith Christ hath madç us free and be not entangled again in the yoke of bondage,” and if men insist on legislating where the Word of God does not, let us not follow them or be moved by them.
