If you’re open to learning how an opponent of Infant baptism argues, I do not recommend the following. Then why did I post it. First, because many people tend to listen to John MacArthur and run uncritically with everything he says. Second, that if you’re going to oppose someone like a Presbyterian and their practice of paedobaptism (infant baptism), then you owe them the decency of representing their viewpoint accurately. Do not build up straw men, only to tear them down, misleading your hearers who have trusted you to represent your opponent’s view accurately.
I DO NOT recommend or endorse John MacArthur’s outright misrepresentation of the paedobaptist position.
