In William P. Young’s 2007 best-selling novel The Shack, Mackenzie “Mack” Philips encounters an allegorical Trinity deep in the woods of the American Northwest: After discovering his daughter has been abducted by a serial killer, Mack finds rejuvenation in the presence of Papa, Jesus, and Serayu. Many in the Christian community claimed that Young’s reliance on graven imagery and modalism detracted from his depiction of the Trinity, however, others praised the novel for making complex doctrine accessible. Essential to the dialogue was how contemporary evangelicals understand and visualize a doctrine as essential to the faith, yet as otherworldly as the Trinity.
