[1] Wellum has degrees from Roberts Wesleyan College and Trinity Evangelical Divinity School.
He has written numerous academic articles and contributed to books on various aspects of theology.
Due to the theological claims among some in New Covenant Theology, particularly regarding a covenant at creation with Adam and the active obedience of Christ, Wellum decided to disconnect the movements in his latter work of collected essays titled, Progressive Covenantalism: Charting a Course Between Dispensational and Covenantal Theologies[5] and in the revision of Kingdom through Covenant.
The various scholars who wrote for the book Progressive Covenantalism demonstrated just how widespread the movement had become and how connected it was to evangelical academies.
Wellum has also co-authored a lay-level biblical-theological account of Christology with Trent Hunter titled, Christ from Beginning to End: How the Full Story of Scripture Reveals the Full Glory of Christ.
