1 Corinthians 5:7
Get rid of the old yeast [i.e., of sin, and especially the unrepentant sinner], so that you can be a new batch of dough, without yeast in it [i.e., a godly church without unrepentant sinners in it] as [I know] you really are. For our Passover [Lamb], Christ, has already been sacrificed.
So, Jesus answered them, "Truly, truly, I tell you, unless you eat the physical body of the Son of man and drink His blood, you do not have [spiritual] life in yourselves [Note: The references to "body" and "blood" throughout this section allude to taking Jesus' life and teaching into one's heart. See verse 56].
1 Corinthians 11:27
Therefore, whoever eats the [Lord's] bread or drinks from the Lord's cup in a way that is unworthy [of them. See verse 21], will be guilty of [dishonoring] the body and the blood of the Lord.
1 Corinthians 10:3
And they all ate the same spiritual food [i.e., the supernatural manna. See Ex. 16:4-5],
Truly I tell you, wherever this Gospel [message] is preached in the whole world, what this woman has done [for me] will [also] be told about, as a memorial of her [kindness to me]."
I am the bread of life.
