Purge out the Old Leaven

[GHansen]

“Purge out the old leaven, that ye may be a new lump, even as ye are unleavened” (1 Cor. 5:7).

14. Now, how shall we explain the fact that he bids them purge out the old leaven that they may be a new lump, when at the same time he admits them to be unleavened and a new lump? How can these Corinthians be as true, unleavened wafers, or sweet dough, when they have yet to purge out the old leaven?

This is an instance of the Pauline and apostolic way of speaking concerning Christians and the kingdom of Christ; it shows us what the condition really is. It is a discipline wherein a new, Christian life is entered upon through faith in Christ the true Passover; hence, Easter is celebrated with sweet, unleavened bread. But at the same time something of the old life remains, which must be swept out, or purged away. However, this latter is not imputed, because faith and Christ are there, constantly toiling and striving to thoroughly purge out whatever uncleanness remains,

15. Through faith we have Christ and his purity perfectly conferred upon ourselves, and we are thus regarded pure; yet in our own personal nature we are not immediately made wholly pure, without sin or weakness. Much of the old leaven still remains, but it will be forgiven, not be imputed to us, if only we continue in faith and are occupied with purging out that remaining impurity.
