Yup.
In fact, all doctrine matters.
If you go to a church that just teaches Jesus loves you, why go to church. After all, Jesus loves you. I can sleep in and it doesn't matter.
After all, Jesus loves you.
In Jude, verse 5, the English Standard Version uses a textual variant. From what I've read, it's the better attested reading, but it's jarring.
Now I want to remind you, although you once fully knew it, that Jesus, who saved a people out of the land of Egypt, afterward destroyed those who did not believe.
Jesus loves, who?
