I might have posted this before but the trinity always reminds me, apart from Carrie Moss, of a sitcom - ' And the Holy Ghost makes 3!', where you see God the Son arrive home and hear the voice of God the Father shout 'have you tidied your room', cut to picture of room untidied which GtF knew cos he's omniscient. GtS shouts 'Yes, dad.', cut to room now tidied, which is cos he's omnipotent, and then the HG appears through the Spirit flap.
