The foundational requirement cannot be achieved by infants.
The reason why paedobaptists baptize infants is simple: It is a remedy for the guilt of original sin. The vast majority of Credobaptists do not believe the guilt of original sin at birth, so the work-a-round for the hope of infant death without baptism is
theological innovation called “The Age of Accountability.”
Baptists concerning whether children sin, believe that mankind inherits Adam’s sinful nature, which is an inclination to always sin.... a disposition towards sin - that it sets us up to be sinners, but we are not actually sinners until they knowingly transgress the Law.
There are two ways Baptists explain this.
1) Infants and children are born with no personal sin and guilt (or least morally neutral), and become sinful when they first consciously sin at the Age of Accountability. Their own inherit righteousness allows them to have no personal sin or guilt.
2) Infants and children do sin. They covet, lie, tease, start fights, act up in class, rebel against parental authority, throw tantrums, etc. However, these sins are not held against them until the age of accountability, when they consciously sin. Their own inherit righteousness allows them to have no personal sin or guilt.
Dismantling AoA is relatively easy as it is an foreign belief which as no foundation at all in Scripture.
Paul in Romans 5 assumes all humanity in two categories.
Those that are in Christ and those that are in Adam. Paul's argument about the these two categories humanity can be clearly seen in his four examples developed in a Thesis/Antithesis structure.
Vs. 16 Adam brought Judgment, Christ brought Justification
Vs.17 Adam brought Death, Christ brought life.
Vs 18 Adam brought Condemnation, Christ brought acquittal.
Vs 19 Adam brought sin, Christ brought Righteousness.
Paul further develops the two categories of humanity in I Cor. 15:22 "
For as in Adam all die, so also in Christ shall all be made alive” showing on judgement day, spiritual death and spiritual life will be made abundantly clear to all of humanity.
Our Lord also maintains all of humanity divided into TWO categories, “that which is born of flesh is flesh, that which is born of spirit is spirit.”
The TWO categories of humanity can also be see in Jesus teaching from the parables: Wheat and Tares, Sheep and Goats, Parable of the Dagnet (separating the good fish from bad, Matthew 13), The two sons, Wise and Foolish Virgins, Wise and Foolish Builders and the Marriage Feast.
However, Baptists have formulated an alternative theory of how many categories of humanity there are.
For Baptists, infants are NEITHER IN CHRIST NOR IN ADAM for the same reason…they don’t have guilt before God due to their own inherit righteous. Here we see a development of a
THIRD CATEGORY foreign to Scripture.
This places infants in a strange and obscure
THIRD CATEGORY which we have heard before….the old Roman Catholic doctrine of
limbus infantum. This is where all the unbaptized infants went to after death. Rome no longer holds to this doctrine.
Only credobaptists today hold to this most horrid theological innovation of the THIRD CATAGORY…the Age of Accountability.
The “Age of Accountability” is just warmed over dead Roman Catholic dogma repackaged for baptistic consumption.
