Residential Doctoral Programs
Students entering doctoral studies at Liberty Theological Seminary come from diverse academic and ministry backgrounds. Here, they prepare for future academic and ministry endeavors, including research and writing, teaching and ministering, full-time church work, cultural engagement, and parachurch ministry.
Liberty Theological Seminary’s residential doctoral programs foster mentorship between faculty and students and offer degree programs that are integrative and interdisciplinary in approach.
Residential Ph.D. Degrees
In the Ph.D. in Biblical Studies program, students will have the opportunity to take courses in biblical theology, Old Testament, New Testament, Greek, and Hebrew. Here, students can engage rigorously with the biblical Greek and Hebrew languages and examine Old and New Testament literature in their ancient historical contexts.
In the Ph.D. in Theological Studies program, students can take courses in theology, apologetics, church history, and biblical theology. This degree prepares students to integrate and think wholistically—biblically, historically, philosophically—about core Christian doctrine while also equipping them to defend the Christian faith.
Faculty from Liberty Theological Seminary and the John W. Rawlings School of Divinity serve as mentors helping students to develop both academically and spiritually. They aim to prepare students to serve inside and outside of academia, coming alongside the local church to fulfill the Great Commission.
