Baptism a Cardinal Doctrine? (QoW #994)

A listener named Chris pushes back on Dr. Craig's video "What About Baptism?", where Craig said baptism "is not a cardinal doctrine that need divide us." Chris argues that Galatians teaches only one true gospel — so if baptismal regeneration (the belief that baptism is necessary for salvation) is wrong, its proponents are preaching a false gospel, making fellowship with them untenable. Dr. Craig responds that Chris has misread the sacramentalist position: those who hold to baptismal regeneration don't see baptism as a meritorious work, but as one more means of grace, like preaching or Scripture reading. Craig explains why he can disagree with fellow baptized Christians on this point without treating them as false brethren.
