Richard Ganz in his book, 20 Controversies That Almost Killed A Church - Paul's Counsel to the Corinthians and the Church Today, wrote concerning I Cor. 5, that many churches are like the Corinthians, they pat themselves on the back for being a great church ... but they do nothing about sin. And, if a minister or elders try to practice church discipline, they may find themselves put out of the church. He reminds us that Jonathan Edwards, one of the most influential preachers since John Calvin, was expelled from his church by a vote of 231-23 for saying that people who were involved in open, unrepentant sin could not take the Lord's Supper. Edwards said there was going to be discipline for sin. John Calvin was also thrown out of Geneva when he tried to practice church discipline. Ganz observes, "If Jonathan Edwards and John Calvin can be thrown out of their churches, how many pastors are safe?"
