I don’t think it is necessarily bad grammer, maybe it is obsolete? Keep in mind I am not a native speaker.
“Risen” in this case is not a verb but acts more like an adjective, “the one who has risen”. I always interpret sentences like this as “He is the one who has risen.”
Christians fucking hate grammar. He has risen or He is rising. Why this monstrosity?!

I think the simple explanation is they suck at grammar and write “He’s risen” not recognizing the 's with the auxiliary verb means has.
