Christianity is a historical Faith. Christianity is rooted in the historical facts of Jesus's life. The Church, which is His Body, has lived, grown, and matured in space and time. The surest way to know Jesus and His Church is through the study of history, both biblical and post-biblical.

We hope these resources take you deep into the history of Christ's Church and thereby deeper into Christ.
