Welcome to this week’s Trekabout, where we give you a master course in Christian theology. In the beginning (“The Apple”), God was there with some guys and gals, and then Satan (Kirk) came and gave them the knowledge of good and evil (sex). Skip ahead a while (“The Doomsday Machine”) and God (Starfleet) sends his Son (Commodore Decker) to atone for the sins of the world. Plus! Shut up, Chekov.
