He didn’t say a church with no sinners. He said a church with “wicked and WILLFUL sinners advocating homosexuality”. WOuld you want to share church service with a child molester who saw nothing wrong with it, and insisted you accept and celebrate his sickness?
But nice strawman.
Actually what he said was wicked and WILLFUL sinners like open advocating homosexualitys. I took that as an example of willful sinners and assumed that they wouldn't accept others as well. But if it's only one class of "wicked and WILLFUL sinners" that are banned then I stand corrected.
