Ad Fontes: Textual Criticism for Lutheran Laity

Lutheran laypeople already encounter textual criticism—in pew-Bible footnotes, online videos, classrooms, and conversations nobody handed them a framework for. This study supplies that framework in plain language and from within the categories of the Lutheran confession.

The introduction and four lessons stand on their own, include complete citations, and end with assignments you can do using the Bible already on your shelf. Follow along with a live Sunday school class, work through the material with a group, or read at your own pace.

The series is adapted from Ad Fontes: Textual Criticism for Lutheran Laity (first edition, May 2026).
