The Importance of Faith in the Early Church

The idea here is not that you, you know, every single person that you disagree with, internally, you got to like, make sure you never have them in your house. That's not what this is about at all. But what this is saying is that if there is somebody who is teaching falsely about the person and work of Christ, this is the doctrine, the key, the big one. You cannot in any way do anything that would make it look like you affirm the legitimacy of this teaching. Don't muddy the waters.
