There are plenty of scriptural references in the bible in regards to the topic of Baptism to give a good case for the importance of it. The Christian community is divided up into two main sections regarding the nature, method and recipients of baptism. These two sections are paedobaptism and credobaptism.
The paedobaptism simply means baptism of children. We find this practiced mainly among Presbyterians and Anglicans. The basic argument from the paedobaptist regarding the baptism of babies is that the covenant of grace is a continuous covenant even into the NT. There is a continuity of the people of God from the Old to the New Testament hence the Old covenant had covenant signs which were bestowed to children should continue in the New Testament. The sign of the blessings of the New Covenant is, in their mind, baptism. They argue that the household dealings of God towards His people have not changed from the Old Covenant to the New Covenant.
Credobaptism is also called ‘believer’s baptism” and it is practiced mainly by Baptists of every persuasion. Credobaptists see baptism as an outward sign of regeneration which can only be said of believers. (Galatians 3:27) They would hold that we are baptized into His death which denotes a burial (Romans 6:3-4) and this is what the “going under” in the water signified (Mark 1:5).
The question this weekend is which one is biblical and why? Does your church practice either of these or none?
As a bonus, here is an interesting debate on the subject of baptism representing both sides.
