"I am the bread of life" said Jesus. John 6:35.

"Now as they were eating, Jesus took bread, and blessed, and broke it, and gave it to his disciples..." Matthew 26:26.

If "bread" is good enough for Jesus it's good enough for the rest of us.

Your reference to king also gives me the chance to show a piece of Roman cultural imperialism. You would be aware of "INRI" on crucifixes. Well, that was originally in three languages: Hebrew, Greek, and Latin, when put on the Cross to mock Jesus ("Here is Jesus of Nazareth, King of the Jews").
In the intervening centuries the Hebrew and Greek have quietly disappeared, leaving just Latin. That of course was part of the process of making Latin the "official" language of the Church, when in fact the Mass was said in Greek in the first few centuries of the Church.
