Tangents: Collected Essays and Homilies, is a collection of short essays and reflections on Christianity. Why Tangents? Simply because truth can, if at all, be approached only obliquely. Who could claim to have penetrated some inner circle of truth that might be considered its fundamental heart or essence? Perhaps, as human beings, the best we can hope for is to be able to brush against it, in the way that a tangent touches the circumference of a circle, before heading off again into the unknown.
