It is unfortunate that Protestant churches which believe in the presence of Christ in the bread and wine at the Lord's Table have moved away from frequent celebration of the Lord's Supper. Here is what St. Thomas Aquinas said about it:

Under the old law it was the flesh of calves and goats that was offered, but here Christ himself, the true God, is set before us as our food. What could be more wonderful than this? No other sacrament has greater healing power; through it sins are purged away, virtues are increased, and the soul is enriched with an abundance of every spiritual gift. It is offered in the Church for the living and the dead, so that what was instituted for the salvation of all may be for the benefit of all. Yet, in the end, no one can fully express the sweetness of this sacrament, in which spiritual delight is tasted at its very source, and in which we renew the memory of that surpassing love for us which Christ revealed in his passion.

It was to impress the vastness of this love more firmly upon the hearts of the faithful that our Lord instituted this sacrament at the Last Supper.
