EP 43: The Washing We Need, The Old Testament and Baptism - Ft. Dr Jim Renihan

40 minutes

In this episode of the Broken Wharfe Podcast, John-Mark sits down with Dr. James Renihan to explore the Old and New Testament foundations of baptism. Drawing from his teaching series, IRBS On The Road, Dr. Renihan explains how ritual washings in the Old Covenant point forward to believer’s baptism, why circumcision is fulfilled in regeneration—not baptism—and how baptism serves as a pastoral help to Christians.

Whether you’re Baptist, paedobaptist, or simply wrestling with the theology of baptism, this conversation provides clarity, encouragement, and a strong biblical framework.
