Infant baptism can be deducted from Scripture, whether you believe it or not.
No, it cannot. It is believer's baptism that can be deduced from multiple biblical passages (Matthew 28:19; Acts of the Apostles 2:38; Acts of the Apostles 8:36-38; Acts of the Apostles 16:31-33; Romans 6:3-4). This last one is particularly strong: read it all and actually think about whether you can really say that of a child who is forced to be baptised.
The thing is that our churches (Lutheran, Anglican, etc.) look to the early Church for evidence when something seems to be ambiguous in Scripture, because 1. They're very close to the Apostles chronologically (Irenaeus, who is often used to defend infant baptism, was a disciple of a disciple of John the Evangelist) and 2. We trust that God wouldn't let his Church fall into error in such pivotal matters, especially that early on. The churches with roots on the Reformed and Anabaptist traditions (like yours) tend not to take this approach.
That approach does not sound like
Sola Scriptura, but rather like
Prima Scriptura (I'm not sure this term exists, though) — it sounds like you're just saying ‘We are guided primarily by Scripture and secondarily by other things’, rather than ‘We are guided solely by Scripture’. The Bible, I believe, is sufficiently clear to condemn infant baptism.
Let us also not forget that the unbiblical practice of infant baptism gave origin to the unbiblical practice of baptism by aspersion, rather than the biblical practice of baptism by immersion.
So it's all much more complicated than just saying that "it's clearly not in the Bible".
No, it's not. It's just that simple: it is not in the Bible, regardless of how you look at it. Only if you insert your own ideas into the Bible will you find it there.
And yes, I'm helping to derail the thread now too. It's already been lost anyway...
The earliest Christians appear to have concentrated on baptising adult converts, which is to be expected when a new movement is taking in lots of new converts. But we don't know that they didn't also baptize young children.
Yes, we do. They baptised converts, as Jesus had commanded them (Matthew 28:19), illustrating a change in life (Romans 6:3-4). We also know that they baptised by immersion — because the writers often used expressions like ‘coming out of the water’ (Matthew 3:16; Acts of the Apostles 8:39) —, which would make it unreasonable to baptise babies.
Because there is a strong suggestion in Scripture (yes, there is) that they did so, we feel that baptising children is proper. This is a good example of Sola Scriptura in operation.
No, there is not. There is a much stronger suggestion that baptism is for those who believe.
In addition, I have always thought that the churches that stand firmly on ''Believer's baptism" are badly confused in another way. Most of them DO baptise children who are too young to really understand a commitment to Christ that's much more sophisticated than "Jesus loves me, this I know." Their argument then becomes "INFANTS shouldn't be baptized," which is merely to focus on some children too young to make a genuine commitment while rejecting other children who are also too young to do that.
We believe that only those who are capable of believing should be baptised. Now, evidently, the age at which a child becomes mature enough to be baptised is debatable and varies from child to child — which is why we believe that children born ‘in the church’ who wish to be baptised should be profoundly accompanied, so that the church may judge whether they believe that the child is sufficiently mature to understand what the commitment of following Jesus, which is symbolised by baptism, truly entangles. At my church, we run a class of preparation for baptism, which takes approximately three months, in which every candidate for baptism receives an introduction of the basic doctrines of the Christian faith.
I was baptised on 02 January 2011, when I was 12 years old, in the 7th year at school. I would hardly consider myself ‘[a child] too young to make a genuine commitment’ at that time, as you wrote; I was more of a pre-teen than an actual child. In our Baptist churches, it would be quite rare for us to baptise anyone much younger than this. I believe that the early teen stages are, in a general way, a reasonable age for baptism. Of course, the actual best age varies, but I think that shortly after leaving ‘the single digits’ is a generally good idea.
Again, though, it is important that the person in question always understands what baptism implies, which is precisely what happened to me. We adamantly reject baptising children too young to understand.
I think Acts 2:38-39 and the three mentions of entire households being baptised are already enough evidence that infant baptism can be deducted from Scripture. Denying that won't do any good.
No, it is not, because we are not told whether those households included any young children. If they did not (which seems likely), the doctrine of believer's baptism remains undamaged and infant baptism remains refuted.
