This year, we will consider, “100 Years of Christianity and Liberalism: J. Gresham Machen’s Theological Legacy.” This year marks the one-hundredth anniversary of the publication of J. Gresham Machen’s Christianity and Liberalism. We will take the opportunity to consider his unique contributions by exploring several covenantal and eschatological themes he identified throughout the Old and New Testaments.


This conference is proudly supported by our valued sponsors, Harvest USA and Heidelberg Seminary.

We extend our heartfelt thanks to our sponsors for their generous support. We encourage you to explore their websites to learn more about their labors in service of Christ and his church.
