- Believers-baptism is the default position. It does take time and care to argue for infant baptism, just as it takes time to argue for predestination or the Trinity or the two natures of Christ. This doesn't necessarily make it 'too many steps of extrapolation'. Some theological structures just take time to establish. Especially if we are clearing the ground of pre-existing ideas and assumptions.
- Baptism is never defined in Scripture as being only for believers. It is often used in metanomic figures of speech (eg Rom 6, Gal 3) to stand for repentance, faith and conversion. But this does not mean that baptism is primarily a sign of faith. The closest we come to this is 1Peter 3:21. But even here, is God saying 'baptism can only be given to someone who is capable of a rational pledge of conscience' or 'baptism is only true, saving baptism when it is accompanied by a rational pledge of conscience'?
- Better to see baptism primarily as a sign of God's grace, God's gospel, God's promises. Adult converts receive the gospel, and hence the sign of the promises of the gospel. Children are raised under the preaching of the gospel, raised inside the visible church. On this grounds alone, it is fitting to mark them with the sign of the gospel which has been held out to them from birth. But more, the OT and NT argue that God has a 'general electing love' for the physical offspring of his people (see 8 below). Baptising them is an expression of this love.
- I like the section in Calvin's Institutes of the Christian Religion on infant baptism. A lot of arguments for infant baptism that have become simplistic and sloppy in the hands of later apologists - such as 'Let the little children come to me' - are written with care and subtlety by Calvin.
- A believers-only view of the visible church feels very 'modern': a voluntary society of individuals. Do you know what I mean?
- From a believers-baptism point of view, it is hard to know how to make sense of children of Christians. Are they the same as any other non-Christian guest? Not really. Surely they are 'members of the church' in some sense.
- Baptising a child at birth is said to be artbitrary and without scriptural warrant. At the same time, most believer-baptists hold off on baptism until some arbitrary point. Few believer-baptists baptise confessing two-year-olds. If we are going to baptise kids of Christian parents at some abitrary point, perhaps birth is as representative as any other time.
- John 1, Romans 2 and other such passages are not saying that physical descent has no significance whatsoever. They are merely saying that physical descent is not the *necessary* nor *sufficient* ground for eternal salvation. Romans 3, 9, 11 and 15 all teach us that there is significance to physical descent. There is a 'general electing' love of God as well as a 'individual electing' love of God.
- Colossians 2 does not say (as some infant-baptists argue) that baptism *is* the New Testament's circumcision. There are four steps (1. In Christ circumcised 2. With circumcision of sinful nature 3. Having been buried with Christ 4. Through baptism) not two steps (1. In Christ circumcised 2. Through baptism). But what it does teach is the the spiritual significance of circumcision and baptism is the same. They may not be identical but they are parallel.
- We must pay more careful attention, brothers, to the way we use Covenant of Grace and New Covenant. As a rule, the believer-baptist has a stronger emphasis on the distinctions between Old and New Covenant. They tend to use 'New Covenant' to speak about the things that are particularly unique about the new dispensation. Infant-baptists are a little more vague. 'New Covenant' can mean simply 'the Covenant of Grace as experienced in the new dispensation'. For a believer-baptist, 'member of the New Covenant' means 'regenerate, predestined person who *will* go to heaven'. For an infant-baptist, 'member of the New Covenant' can often just mean, 'member of the Covenant of Grace, even purely because they are members of the visible church'.
- Believer-baptists often consider the visible church to be responsible for making sure the church is only made up only of the Elect. It is an "opt-in" ecclesiology: you can only join if you can prove your conversion. You might say the believer baptist *presumes* to purify the visible church. Infant-baptists often consider the visible church to be responsible for accpeting all who confess faith, and disciplining those who betray their confession. It is an "opt-out" ecclesiology: you are only rejected if it your unbelief can be proved. The infant-baptist *assumes* that a person's confession is true unless evidence is given to the contrary.
