“‘Who is God?’ There is no more central—or highly debated—theological question. Drawing on the riches of the Christian, and specifically Catholic, tradition, as well as contemporary cultural resources, John Markey’s Who Is God? is learned and poetic, engaging and accessible. Markey and his colleagues Greg Zuschlag and Paul Contino, master teachers all, have provided an excellent and creative text for a broad readership. Highly recommended for undergraduate students, pastoral ministers, faith-related discussion groups, and all engaged in the quest for ultimate meaning in human life.”
