Gary Leonard (Banned by HWA) recently asked "Is Jesus impressed with your deleavening routines?" The question is, of course, directed at ACOG members who obsess over the removal of leavening agents from their homes and vehicles in preparation for their observance of the Feast of Unleavened Bread. For most of that culture, it's all about the symbolic meaning of an ancient religious ritual of the Israelites. The removal of leavening being likened to ridding their lives of sin.
It is ironic that many of them point to the fifth chapter of Paul's first epistle to the Corinthians to justify this activity. They use this passage as one of their chief proof texts in demonstrating the continuing obligation of Christians to participate in the ritual, while many of them ignore/overlook the point that the apostle was attempting to make.
Paul wanted the Corinthians to remove pride, malice and wickedness from their midst and replace them with sincerity and truth. Which brings a question to mind for all of the folks who are still engaging in the physical ritual: Are you busy cleaning your house and car and purchasing matzah bread? OR Are you preoccupied with getting rid of the pride, anger and bitterness from your life and replacing them with the qualities that God wants you to exhibit? Which one of those activities do you suppose God is really interested in?
