This session examines baptism in the Old Testament, challenging the common Presbyterian argument that circumcision is the Old Testament equivalent of baptism. The speaker argues that Baptists have allowed Reformed paedobaptists to set the terms of debate and seeks to reclaim the home field advantage by taking circumcision off the table as a baptismal argument. The session demonstrates that baptism must be understood through different Old Testament categories and precedents, not through the covenant theology framework typically used to support infant baptism. This is the first part of a three-part seminar designed to equip Baptist churches against arguments for infant baptism. Scripture references: Various Old Testament passages related to ceremonial washings and religious practices.
