St. Theodore the Studite wondrously describes the benefit one receives from frequent Communion:
Tears and contrition have great power. But the Communion of the sanctified Gifts, above all, has especially great power and benefit, and, seeing that you are so indifferent towards it and do not frequently receive it, I am in wonder and great amazement. For I see that you only receive Communion on Sundays, but, if there is a Liturgy on any other day, you do not commune, though when I was in the monastery each one of you had permission to commune every day, if you so desired. But now the Liturgy is less frequently celebrated, and you still do not commune. I say these things to you, not because I wish for you simply to communehaphazardly, without preparation (for it is written: But let a man examine himself, and so let him eat of the Bread, and drink of the Cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lords body and blood [1 Cor. 11:2829]). No, I am not saying this. God forbid! I say that we should, out of our desire for Communion, purify ourselves as much as possible and make ourselves worthy of the Gift. For the Bread which came down from heaven is participation in life: If any man eat of this bread, he shall live for ever: and the bread that I will give is My flesh, which I will give for the life of the world (Jn. 6:51). Again He says: He that eateth My flesh, and drinketh My blood, dwelleth in Me, and I in him (Jn. 6:58).
