IMO, if you name your band after Jesus and Mary, in any particular fashion, then you should be a Christian band. Commenting on the guitar skills of Eddie Van Halen shouldn’t even be mentioned, because it wouldn’t be something a Christian band would care about.
If they’re not a Christian band, and using that name, it’s almost like taking the Lord’s name in vain. Certainly not worth my time.
I didn’t even no Van Halen was religious. Didn’t he have songs about the devil.
