An old saying goes: “You are what you eat,” meaning your body becomes what you feed it. But we also need an eternal life providing substance, spiritual food, to provide the nourishment of Christ within us.
Men of medicine have long advocated that “your strength and vigor depend on what you eat.”
“Everything you eat becomes a part of not only your inner being, but the outer fabric of your body as well,” according to Web MD.
“Jesus answered, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.'””
– Matthew 4:4
The “you are what you eat” concept can be extrapolated further in a religious sense. What we take into our minds also becomes part of our being. If we want to become Christ-like, we have to consume ideas that feed our minds Christ-like thoughts.
What that means is that we also need the food of the spirit.
The word of God is food for the soul. Material food gives life to the mortal body on earth. Spiritual food is necessary for eternal life.
“For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live.”
– Romans 8:13
The theological term “Eucharist,” comes from the Greek word eucharistia, meaning ‘thanksgiving.’ It is known as communion or Holy Communion, which commemorates Christ’s last meal with his disciples, via a reenactment of the Last Supper.
“And he took bread, and when he had given thanks, he broke it and gave it to them, saying, ‘This is my body, which is given for you. Do this in remembrance of me.’ In the same way, after the supper he took the cup, saying, ‘This cup is the new covenant in my blood, which is poured out for you.'”
– Luke 22:19-20
The idea of “you are what you eat,” plays a part in the sacrament of the Eucharist practiced by Roman Catholics via transubstantiation.
The Eucharist becomes a transubstantiation, which according to the Catholic Church means, “the change of the whole substance of bread into the substance of the Body of Christ and of the whole substance of wine into the substance of the Blood of Christ.”
According to Catholic beliefs, and those of some other Christian churches, transubstantiation transforms the substance of the bread and wine of the Eucharist into becoming his body and blood – bringing Christ actual presence. In other words, as we ingest this food, we become “you are what you eat”
“I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.”
