What else are we praying for in this petition?)(What is the bread of subsistence for the soul?

Since we are a unity of body, soul, and spirit, we may and should ask, for the soul also, that bread of subsistence without which the inner man perishes of hunger. The divine Scriptures compare the Word of God to bread, as the Lord himself, citing Deu 8:3, answered the tempter: “It is written, ‘Man shall not live by bread alone’” (Luk 4:1–4).

Another form of ‘daily bread’ is the Bread of Life, communion in the Body and Blood of Christ: “The cup of blessing which we bless, is it not a sharing in the blood of Christ? The bread which we break, is it not a sharing in the body of Christ? Since there is one loaf of bread, we, who are many, are one body, because we all partake of the one loaf” (1Co 10:16–17; see Q570). As St John of Kronstadt exclaimed:

I fade away, I die spiritually whenever I do not serve in church for several days… The Holy Mysteries give life to my soul and body. After Communion, I become like another person: clear, radiant, strong. If I do not commune, I feel myself bound, weak, blind. (My Life in Christ)

Finally, the Lord himself teaches that doing the will of God is itself food: “I have food to eat of which you do not know… My food is to do the will of him who sent me, and to accomplish his work” (Joh 4:32–34; see Q414).
