Is John MacArthur Wrong? - Fined $20,000 For Church Assembly

Pastor John MacArthur and Grace Community Church continue resolute with in-person church meetings, despite the Governor's orders and local fines of $20,000 thus far. Some Christians question the wisdom of the stance, and others just plain think the pastor is in sin. Is this a matter of agreeing with your adversary quickly while you are in the way with him, or is the church and worship of higher importance and worth the risk of breaking the law and spreading a virus?
