1 Corinthians 5 · a question people ask

"Purge out the old yeast, that you may be a new lump, even as you are unleavened." (5:7). If they are unleavened already, why purge out the old yeast?

In the text

The verse says both, side by side: "Purge out the old yeast", and "even as you are unleavened" (5:7). It has just asked, "Don’t you know that a little yeast leavens the whole lump?" (5:6). The chapter doesn't say more of how the two go together than these words, and these notes don't either.

The verses

“Your boasting is not good. Don’t you know that a little yeast leavens the whole lump? Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place.”
1 Corinthians 5:6-7 · World English Bible

From Favor's study of 1 Corinthians 5

1 Corinthians 5: A new lump

1 Corinthians 5 calls Christ "our Passover" (5:7), in the same verse that says both "Purge out the old yeast" and "even as you are unleavened" (5:7). The next words are "Therefore let’s keep the feast" (5:8). In the WEB's 1 Corinthians, yeast stands only in 5:6-8.
