Series of lectures originally delivered in Edinburgh, Scotland on the Croall Foundation at the end of 1911. The lectures covered the original manuscripts, their language, their literary character, and their circulation, and a collection of New Testament writings.

These essays form on the one hand an exploration of the Spirit in the New Testament, and on the other hand a demonstration of the spirit of the NT. The emphasis is on the Johannine literature, but there are also studies in Matthew and Luke.
