The belief that baptism is necessary for salvation is a long-standing and widely accepted doctrine in most Christian traditions. However, some argue that exceptions found in the Bible, like the thief on the cross, invalidate this requirement. This argument, known as the “argument by exception,” is flawed.
Early Christians universally believed in the necessity of baptism for forgiveness of sins and entrance into heaven. Protestant scholars like JND Kelly and William Webster acknowledge this in their writings. Kelly, in his book on early Christian doctrines, notes that baptism was seen as a way to remit sins, not just as a symbol of faith. Webster also points out that the doctrine of baptismal regeneration was universally accepted by the early Church Fathers.
Some modern Protestants argue against baptismal regeneration by citing biblical exceptions. For example, Baptist pastor Mike Winger argues that there are examples in the Bible of people being saved without baptism. While it’s true that there are exceptions, such as the thief on the cross, these do not invalidate the general rule that baptism is necessary for salvation.
The “argument by exception” fallacy occurs when someone uses an exception to try to disprove a general rule. For example, just because ambulances can speed in emergencies, it does not mean everyone can ignore speed limits. Similarly, using biblical exceptions to argue against the necessity of baptism commits the same logical error.
Most Christians agree that baptism is conditionally necessary—generally required but with exceptions in extreme circumstances. God usually provides grace through sacraments, but He is not bound by them. This is similar to how, in rare cases, a person who has never heard of Jesus might be saved, yet the general rule remains that belief in Jesus is necessary for salvation.
If baptism is universally accepted as necessary for salvation, then it follows that eternal security is not. Early Christians believed that a genuinely saved person could lose their salvation, as not everyone who is baptized remains a Christian throughout their life. Therefore, arguing that Christians cannot lose their salvation while also rejecting baptismal regeneration is inconsistent.
Using exceptions like the thief on the cross to argue against the necessity of baptism for salvation is an example of the “argument by exception” fallacy. This faulty reasoning tries to invalidate a widely accepted principle by citing rare exceptions. The early Church unanimously upheld the doctrine of baptismal regeneration, and exceptional cases do not undermine this long-standing belief.
