Host Jerry Eicher (Anabaptist Theological Perspectives) quotes scholar Ken Wilson, PhD, on his research of Augustine and the origins of Augustinian Calvinism. The episode summarizes Wilson’s abbreviated booklet based on his PhD thesis, explaining his methodology and main claims.

Topics covered include a chronological reading of Augustine’s works, comparisons with Stoicism, Neoplatonism, Gnosticism and Manichaeism, the early church fathers (patristics), and Augustine’s responses to Pelagianism. Wilson argues Augustine’s later deterministic theology—adopted by Luther and Calvin and crystallized in TULIP—was shaped by pre-Christian Manichean and Gnostic influences rather than the first three centuries of the church.

Key points: Augustine’s suspension from an early rule barring former Manicheans from office, brought about a decisive shift to non-free will around 412 CE, the reintroduction of “damnable guilt” and radical grace, and the claim that many scriptural interpretations used by Reformed theologians trace back to pagan determinist sources. Listeners should expect a concise, scholarly overview of Wilson’s argument and its implications for how we read Augustine and the foundations of Calvinism.
