Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?
Your glorying in your attachments and your teachers (1 Corinthians 3:21), while all the while ye connive at such a scandal, is quite unseemly.
A little leaven leaveneth the whole lump (Galatians 5:9) - one bad member infects the whole church. Little thieves let in greater ones. With present complicity in the guilt, and danger of future contagion (1 Corinthians 15:33; 2 Timothy 2:17).
