"A Summary of the Christian Faith" is Henry Eyster Jacobs' magnum opus. It is a systematic theology of the Christian faith written in a catechetical format from a Confessional Lutheran perspective. The work is written in a series of questions and answers on various doctrinal topics. Throughout the work, Jacobs defends his views through use of Scripture and the Lutheran fathers. This text is readable enough to be studied by the layman but with enough depth to teach the learned pastor and scholar."
