In this episode, Grettelyn and Joe continue their conversation on the Church season of All Hallows' Tide, looking at Prayers for the Dead and the Church's discipline of Indulgences. Then, they wrap up with a brief chat about Halloween and how Christians can celebrate it, even some of the "spooky" bits like skeletons!
