How important is doctrine to Jesus? Very! So important is right teaching to Jesus that He says anyone who runs ahead and does not continue in it does not have God. "Anyone who runs ahead and does not continue in the teaching of Christ does not have God; whoever continues in the teaching has both the Father and the Son. If anyone comes to you and does not bring this teaching, do not take them into your house or welcome them. Anyone who welcomes them shares in their wicked work" (2 John 1:9-11).
