Our largest package, the 2025 Ultimate Library, provides an incredible library for biblical research and theological reflection. Whether focused on Church history or biblical exegesis, the vast collection of resources and titles at your fingertips cover the gamut—from most devotionals to practical discussions of pastoral ministry to the most rigorous scholarly and academic research. This package has everything you need to engage in the serious study of Scripture and its world, with respected resources like the Library of Hebrew Bible/Old Testament Studies | LHBOTS (382 vols.) and top-tier exegetical commentaries like the New International Commentary on the Old and New Testament | NIC (51 vols.).

This useful and insightful volume aims to illustrate, espouse, and renew the discipline of doctrinal theology, particularly as exemplified historically by Martin Luther and his theological reflection on the Trinity.

The Lutheran Portfolio library makes your study of the Bible easier by connecting your entire library of books to a robust set of study tools. The Lutheran Portfolio Library takes everything in the Lutheran Diamond Library and adds even more to your library. The Lutheran Portfolio LIbrary contains key sets including Anchor Yale Bible Dictionary | AYBD (6 vols.), Stuttgart Scholarly Editions: Core Bundle, Anchor Yale Bible Commentary | AYBC (94 vols.), UBS Handbooks Series: Old Testament, New Testament, and Deuterocanonical Books (66 vols.), and many more. The Lutheran Portfolio Library is excellent for academic research or advanced exegesis.
