I’m somewhat hesitant to post this, as my views are not fully formed, it’s a comment on a major source of disunity in the church, and many greater minds than myself have come to a different view on this.
But what is blogging for if not to discuss a few ideas, while practicing discernment?
With that in mind, read this passage assuming that the early church had a normative practice of infant baptism:
3 Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? 4 We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. 5 For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his.
(ESV)
If you suppose all-age baptism in the early church, what is the most obvious interpretation of this? Surely that all of us who have been baptised with water have been spiritually united to Christ, adults and infants alike. You’d be looking around your Roman house church thinking there’s Andronicus and Junia – they’re baptised, so they’re united to Christ. And their two little sprogs, Andronicute and Juniette. They’re baptised too, so Paul is saying they’ve been buried with Christ in his death.
This has some interesting implications. This baptism is not presented as a breakable bond, so surely it means that all the baptised will be saved. Breakable or not, we’re in Federal Vision territory. Does it not also mean that the unbaptised will not be saved since they cannot be united to Christ through baptism? In which case, what about the old “if you confess with your mouth and believe in your heart that Jesus is Lord” line from a few chapters later? Are there two ways to be saved? I’m sure we would all say ‘certainly not!’
Additionally, why exactly would God chose the application of water upon an infant to be the thing that joins them to Christ?
To avoid these issues, you’re forced to say with Dunn that this passage refers to a spiritual baptism leading to a spiritual unity with Christ. But most agree this is unlikely. Or you say, with Calvin, that baptism unites you to Christ conditionally upon faith (and indeed mortification! Institues 4.16.16). But are we to imagine that Paul wanted his Roman readers to keep inserting “and repentant faith” in this passage every time he mentions baptism? No, Paul is really saying that baptism unites you to Christ in his death – we have been united with him.
Let’s try again, this time reading the passage presupposing an early church practice of normative believers’ baptism upon profession of faith.
If baptism stands for the public declaration of faith in the Christ who died for your trespasses and was raised for your justification (Rom 4) then the link between faith and baptism is much clearer. If baptism in the early church presupposes faith, then it is easy to see why Paul is able to use baptism as a kind of synecdoche for faith. It becomes obvious why baptism should unite you to Christ – it does it in the same way faith does. Christians can look back on their baptism as a point where they became united to Christ as they publicly identified themselves with Christ in his death. It’s essentially an intensified, objective expression of faith – a confession with the mouth and with the body that Jesus is Lord.
Obviously this is not to say that all baptisms follow true faith, nor that all who are saved must be baptised. But this passage makes most sense if it was the norm in the early church for baptism to be an expression of an individual’s faith.
