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.📖 What You’ll LearnOld Testament roots of baptism in ritual washingsWhy circumcision points to regeneration, not baptismThe relationship between baptism and confession of faithHow baptism connects with church membership and prudenceBaptism’s pastoral role in assurance and sanctification⏱️ Chapters0:00 – Introduction1:00 – Welcome Dr. James Renihan & IRBS On The Road2:50 – Goals of the baptism seminar9:00 – Baptism in the Old Testament: washings & priestly consecration13:00 – Why New Covenant baptism is one washing19:00 – Circumcision and regeneration in the New Testament21:00 – Timothy’s baptism and confession of faith25:00 – Credobaptism vs. “adult baptism”27:00 – Baptism, church membership, and prudence with children34:00 – Baptism as pastoral encouragement for believers37:00 – IRBS On The Road 2025–26: Sola Scriptura & the Trinity🔗 Resources & LinksVisit: [brokenwharfe.com] for historical reprints, covenant theology resources, and more.Book highlight: Nehemiah Coxe on Covenant Theology with John Owen on Hebrews 8, newly available - Covenant Theology: From Adam to Christ [brokenwharfe.com/bookshop]Invite Dr. Renihan or Dr. Scheiderer to your church through IRBS On The Road: [irbs.org] Send a textContact Broken WharfeTweet us @BrokenwharfeFind us on Facebook at BrokenWharfeFollow us on Instagram at BrokenWharfeEmail us at [email protected] for listening!
