Adam and Bethany are back with their Diving Deeper series, and welcome back Pastor John Bombaro to unpack one of the most debated topics in modern American Christianity: infant baptism. 

Drawing from Scripture, the early church, and church history, Pastor John explains why the historic, global Christian consensus has baptized infants, how baptism is God’s saving action (not our personal performance), and why that matters for assurance, parenting, and everyday discipleship.

They will cover:

• The historic Christian consensus on baptizing infants (Catholic, Orthodox, Lutheran, Anglican, Presbyterian, Methodist)


• Why baptism is God’s objective promise and action—not our subjective decision


• How Scripture speaks of new birth, washing, regeneration, and forgiveness in baptism


• The Reformation split: Zwingli/Anabaptists vs. the conservative Reformation (Lutheran/Anglican)


• Assurance for weary Christians: why baptism anchors us when our feelings fluctuate


• Mode questions (sprinkle/pour/immerse) and the Didache’s practical guidance


• Parenting through the lens of inheritance: raising baptized children in their own faith
