This might look like an ordinary commentary on Mark's Gospel, but it isn't one. It understands reality as Action, actions, change, diversity, movement, and the dynamic, rather than as Being, beings, the unchanging, the unitary, rest, and the static, and it reads Mark's Gospel in the light of that distinctive understanding of reality. It is all about action, change, and diversity, and it understands God, Jesus, and ourselves as action, change, and diversity. The initial chapter introduces the action-based understanding of reality as action in changing patterns—an actology, rather than an ontology. Then follows a section-by-section close study of the Gospel. The result is a unique and somewhat unexpected reading of the text and a distinctive theology to match.
