She delivers a somewhat heavy-handed but timely moral.
Panel 1: We see Elly and Mike walking past a store-front that shows a Christmas elf wrapping a gift. Mike is smiling at the display while Elly is looking ahead.
Panel 2: Mike is really happy right now because he's in the middle of a display of toys.
Panel 3: A thought occurs to him that snaps him out of his reverie. He asks Elly "If Christmas is more about about God than Santa, how come people talk more about Santa than God?"
Panel 4: Elly says that it's because God does less advertising. How like her to blame God when she could easily clear the time to add spirituality to her life.
Summary: I don't really mind this one actually. Sure, Elly is a bit of a hypocrite in that she's a Christmas-and-Easter church-goer and only ever invokes God as a means of condemning things things she doesn't like; that's not to say that her trite homily isn't on-point.
