If I was put in charge of catechizing a group of new converts, I would first assign this book, and do so with confidence and joy. Not since Rowan Williams' Being series have I been so drawn into a book about the basics of our faith. Reeves is cheeky, articulate, and concise. Read this book first for its contents, and stay for Reeves' style. Its really quite fun.
In terms of content, Reeves is adamant that the doctrine of the Trinity, quite literally, is the doctrine upon which our faith stands or falls. He thus writes:
"For what makes Christianity absolutely distinct [from other religions] is the identity of our God. Which God we worship: that is the article that stands before all others...every aspect of the gospel--creation, revelation, salvation--is only Christian insofar as it is the creation, revelation, and salvation of *this* God, the *triune* God" (15-16).
Before we say anything about the Christian faith, we must say that the Christian God is not the singular Allah, or a tritheistic Vishnu-Brahma-Shiva. No, the Christian God--the one who establishes the very ground of all being, and holds together the cosmos--is three persons that share one essence, and exists together in unity, without competition, division, or confusion. The trinity is the only way we know we are loved. And if we don't know we are loved, then Christianity becomes a joyless, monstrous, fear inducing religion.
I also admire Reeve's answers to some very big questions. For example...
Q. What was God doing before creation?
A. "Before He ever created, before He ruled the world, before anything else -- this God was a Father loving His Son" (21).
Q. Why did the Father send the Son, and why did the Son obey the Father?
A. "The Father sent the Son because of how He so loved [the Son] and wanted that love to be shared and enjoyed; and because [the Son] so loved his Father and wanted that love to be shared and enjoyed. The mission [of Jesus] comes from the overflow of love, from the uncontainable enjoyment of fellowship" (106).
Q. What does the Son offer us in salvation?
A. "To know and grow to enjoy [the Son] is what we are saved *for*" (10).
(to add to Reeves' point, which he later explains: we are saved in order to know and grow in the same love the Father has for the Son, and the Son for the Father. In salvation we do not receive some qualitatively different, fallen-creature style love. No, we receive the same love that the Father had for the Son, for all time. *That* is the reality we are saved for, to enter into and enjoy!)
In all, I commend this book to everyone. Tolle lege! Take and read!
