Wrath could probably help with Jiang Cheng pretending to be a religious figure. Which is, y'know, hilarious. But he has experience up that alley both representing one of the 7 sins/being Satan and seeing all the mortals over time being all pious and religious~ They're usually the ones who are the most sinful, but they sure do like to hold that stand up on a pedestal of purity. They're on the same team so he has reason to, but he would probably be mildly amused by his failed attempts prior to offering advice.
