Once for All Delivered is a podcast seeking to apply God’s Word to all of life. We tackle issues of theology and culture. Our episodes release approximately every two weeks.

OFAD launched as Bavcast at the height of the COVID-19 pandemic in 2020, a weekly show exploring Reformed theology through the works of Herman Bavinck. Originally the show had three hosts (Caleb, Andrew, and Marc Scaturro, now an OPC minister). Marc departed in the summer of 2020 to focus on family and church responsibilities. Andrew’s wife Heidi began assisting with production around that time. Seeking to broaden its focus and cover a broader range of topics, the show rebranded as Once for All Delivered in the fall of 2022. Stephen Evertse was added as a new third co-host in 2025.
