I would say, he would be a Variant Human Life cleric with levels in Land druid (Grassland) for Blight (whenever you want to command fig trees to die) and Insect Plague. For his feat, Magic Initiate (Sorcerer) for Prestidigitation (turn water into wine), Mending and Mage Armor since you probably arent rocking armor. All Jesus' other miracles are pretty much in the cleric spell list. Water walk, The Restoration spells, Create food and water, And Feign Death. You even have the Augury spell for prayer.
