Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: (1 Corinthians 5:7, KJV)

In today’s reading, we see one of the strongest evidences in Scripture for the fencing of The Lord’s Table. Paul makes explicit that Christ was typified in the Passover sacrifice. As part of the preparation for that sacrifice, the people of Israel removed all the leaven from their households for seven days (Exodus 12:19). This preparation foreshadowed the due preparation of the Lord’s table both internally and externally. Communicant members ought to examine themselves (1 Corinthians 11:28) and the church ought to fence the table from those living in sin.

Paul encourages that we be like a new lump, not as old leaven, just as elsewhere he exhorts us to walk in newness of life (Romans 6). The gathering of the Lord’s Supper is a sacred meal which should not be profaned either by division in the body nor by allowing sinful men to partake. Since our Passover lamb has been sacrificed, we no longer serve sin, the old man, the old leaven. To signify this, we must fence the communion table.

Matthew Poole comments:

Christ, who is the true paschal Lamb, is slain or sacrificed for us, and your old man should be crucified with him, and you no longer serve sin.
