Living the Message of the New Testament

This is a solid, professionally structured Catholic theology textbook for middle schoolers, written by someone who spent decades in the classroom — you can feel that experience in how the material is organized. Its audience is genuinely narrow though: it lives in Catholic school curricula and has little traction outside that setting, and at three decades old it has almost certainly been superseded by updated editions. Worth having if you're building a Catholic school library collection, less so for general readers.
