2016 Wesleyan Discipline:1 Corinthians 5:6-7
From Wesleyan Discipline
5:6 Your boasting is not good. Don’t you know that a little yeast leavens the whole batch of dough? 5:7 Get rid of the old yeast, so that you may be a new unleavened batch—as you really are. For Christ, our Passover lamb, has been sacrificed.
