Ghoul Jesus is really just a regular ghoul who dresses up and pretends to be the fabled Ghoul Jesus that a local cult of ghouls worships. He does this to get free money and gifts from the unwitty cult followers. He lives alone in a church that occasionally get visits from the cultist who pilgrimage there to get blessings from Ghoul Jesus.

As Ghoul Jesus is a ghoul both while in and out of disguise, you should have a rasp like Hancock from Fallout 4 as shown by this video: https://www.youtube.com/watch?v=Qbg0QVIpxiU. Of note is that when he is in disguise, you should obviously sound more regal and holier while when he is out of disguise, you should sound tougher and slimier.
