Ad Fontes means "to the sources." Each seminar gathers a cohort of about ten pastors and lay leaders to read primary texts with a Trinity faculty member, for the good of their souls and their ministries.
A seminar opens with a two-day in-person retreat and continues with six to eight online sessions of 90 minutes. Discussion runs in a tutorial style, and participants are expected to have graduate theological training, such as an M.A. or M.Div.

With Dr. Thomas Breedlove
Participants read Books III to V of Against Heresies, where the second-century bishop of Lyons answers Gnosticism with a scriptural case for the goodness of creation and the unity of salvation history. The seminar centers on his reading of Christ as the new Adam and what it shows about God's purpose for human beings.

With Dr. Alex Fogleman
Participants study a theological account of how Christians begin and grow in the faith, then read writings from the tradition to shape a plan for discipleship in their own churches.
