Make sure that no one in your congregation is acting immorally or maliciously or wickedly.

1 Corinthians 5:6-8

6 It is not good that, while you are letting that immoral man continue to be in your congregation, you are boasting about being spiritually mature. ◄You know that a small amount of yeast affects all the bread dough [MET] into which it is put {a woman puts it}./Do you not know that a small amount of yeast affects all the bread dough [MET] into which it is put?► [RHQ] Similarly, one person who continues to sin will have a bad effect on all the congregation. 7 So, just like we Jews expel the old yeast from our houses during the Passover celebration in order that we may have a fresh batch of dough without yeast in it [MET], you must expel such evil people from your congregation. Do that so that you can truly be holy people, as I know that you really are. Remember that Christ was sacrificed {sacrificed himself} so that God could spare us from being punished for our sins, just like the Jews sacrificed lambs during the first Passover celebration so that God would spare their firstborn sons from being killed. 8 So let us celebrate the fact that God has freed us from being punished us for our sins [MET], just like the Jews in later years celebrated Passover to celebrate God freeing them from being slaves in Egypt. They made sure that there was no old yeast in the dough. They ate bread that had no yeast in it. Similarly, we should make sure that there are no people in our congregations [MET] who act maliciously toward others or act wickedly. Instead, make sure [MET] that all those in our congregations are ones who act sincerely and speak truthfully.
