To the credo, baptism is a physical vow, done by a believer, following their verbal profession of faith, in accordance with the example of the New Testament. To the paedo, baptism is the sign of the New Covenant.
Which is correct?
To find out, I intend to examine the logical consequences of both views and see which one more closely lines up with Scripture. I expect this to be difficult, since both views seem very reasonable and there’s no direct statement for either position in the Scripture. John never said, “The ontology of Baptism is X, therefore only baptize group Y.” And Luke never said anything like, “Although Timothy had grown up in a believing household, Paul waited to baptize him until his profession of faith was made credible by his good works.”
So I’m validating the two worldviews through circumstantial evidence, like a police investigator taking fingerprints at a crime scene. Individually each a piece of evidence may not be very compelling, but taken together I hope they’ll present a strong case that one view is right and the other is wrong.
Point 1 – Acts indicates belief before baptism
Issue: Acts indicates that those who professed faith were subsequently baptized.
Credo response: This fits our model exactly.
Paedo response: We also believe that an adult convert must profess faith before being baptized, but we also believe that baptism is a household/headship affair. At Pentecost there men who made the pilgrimage across the world to be at Jerusalem in accordance with the command of Deut 16:16 while their families stayed behind. The record of Acts then is not of atomized individuals professing faith, but of men, family heads, being baptized.
Verdict: Tie. Both sides make a compelling case here.
Point 2 – Households were baptized
Issue: The New Testament records five places where the word household is explicitly used when speaking of Baptism (Acts 10:47-48, 16:15; 16:30-31; 18:8; 1 Cor 10:16-18). For example, in the city of Philippi the jailer believed, then his house was baptized.
Credo: Based on the earlier evidence in Acts, it must be the case that the people in the house first heard the good news from Paul and then believed and were baptized. Nowhere in those verses are children mentioned, so assuming there were infants in the jailor’s household is an argument from silence.
Paedo: All baptisms are really “household” baptisms. The very existence of the word house in the text is evidence that the paedo model is correct—no debate on whether there were children in any particular house is needed. The man is the head of the house (Eph 5:23), the man believed, therefore the house was baptized. In the same way covenants are always headship affairs, so Scripture presents baptism as a headship affair.
Verdict: Paedo. If you adopt the household model as the paradigm then the earlier baptisms in Acts make sense, but if you adopt the individualistic model then the household baptisms don’t really follow. Reducing household to all the individuals living under a roof as the credo wants to do doesn’t give a solid basis for explaining why Scripture should so consistently insist that entire households were baptized in my estimation.
The other thing the paedos have going for them is that in Abrahams day the command to circumcise all the males resulted in a large number adults and an unrecorded-but-presumably-small-number-of infants being circumcised (Gen 17:23). After that, the majority of recipients of the covenant sign were infants. At Pentecost the initialization of the sign in like manner may have resulted in a large number of adults receiving the sign (Acts 2:41), and later the majority of recipients being infants.
Point 3 – Peter said the promise was to their children
Issue: In Acts 2:39 Peter said that the promise was “to you and your children, and all who are far off.”
Credo: Peter should be understood as speaking of three distinct groups, “you [the hearers], your children [those who will one day be old enough to accept], and those who are far off [gentiles who’ll come to faith in Christ much later].
Paedo: Peter should be understood as speaking to two groups, (you and your children) and all who are far off [gentiles]. In grouping “you and your children” together Peter is communicating that Jesus is fulfilling of the promises God made to Abraham.
Verdict: Tie. I can see this both ways.
Point 4 – Children are in the Church
Issue: Acts 21:5 says the children (who were disciples) knelt down and prayed for Paul (and he doesn’t rebuke or correct them for doing this). Then in Eph 6:1-3 and Col 3:20 Paul commands the children who heard his words to obey their parents—meaning they were members of the church with duties and obligations. Is there a difference in the eyes of God between a child who grows up under believing parents and one who doesn’t? Should the children of believers be taught to sing “Jesus loves me”?
Credo: the children should be taught to pray and sing.
Paedo: Greg Welty, a credo-baptist, says, “Parents can have confidence that God hears the prayers of their children to the extent they have confidence that their children have renewed hearts.” If the Baptist paradigm is right then the most logical position is to keep the children from singing Jesus loves me until they make a mature, credible profession of faith and demonstrate they are inside the covenant of salvation. Failure to do this means we’ve sinned by teaching them to presume on the goodness of God or hardened them in their impenitency, since only believers are entitled to the blessings of the church. But this is exactly the opposite of what the New Testament says, and therefore indicates the credo-baptism model is wrong.
Verdict: Paedo wins a small victory. If the credo model is correct then Paul should have instructed the parents to make sure their children obey them, but the text indicates that the children are already part of the church and must act like it. Further, Paul praises Timothy for knowing the Scriptures since infancy (2 Tim 3:14-17), but how would this have happened under a consistent credo paradigm? Credo parents may catechize their children but there’s no mechanism or rational to do so if the church is no larger than the mature professors of faith.
Point 5 – Children in Covenant
Issue: 1 Cor 7:14 says the children of believing parents are holy.
Credo: Holy here means more nearly what we would think of as legitimate. Further, if the children in covenant are holy and should be baptized then the unbelieving adult spouse should also be baptized, but this is an absurd conclusion–which leads us to realize that the premise is false.
Paedo: Holy can't be equivalent to legitimate because the children of a married couple are always legitimate. Instead, Paul’s use of the word holy is invoking covenant language imported from the Old Testament. In the same way that Peter declared Cornelius was not to be called unclean or outside the covenant (Acts 10:28) so too is the child of the believer not unclean, but holy. This is clear evidence that familial solidarity established in the Old Testament remains true in the New Testament, since the mere presence of believing parents sanctifies the child and makes them holy.
Verdict: Tie/Paedo by a hair. The unbelieving spouse is becoming holy, but the children are already holy, which indicates that they already belong to God.
Point 6 – The Warning Passages
Issue: The New Testament warns the reader to guard their salvation; see Mark 13:13; James 5:11; 2 Cor 13:5; 1 Tim 1:18-20, Hebrews 2:1-4; 3:7-19; 6:4-8; 10:26-3; 12:25. But we also know from other passages (like 1 John 2:19; Rom 8:29-30, John 6:38-40; Phil 1:4-6, etc) that it’s impossible for a true believer to lose their salvation. So how do we reconcile these two things?
Credo: The warning passages are admonitions designed to keep the believer on track. Just as a mother warns her children not to jump into a blazing furnace, and the warning functions as the means to avoid death, so too do these warnings provide the means to our perseverance.
Paedo: These are actual warning passages for events that could really occur, given to keep us on track. Those who fall away were inside the covenant but outside salvation, so it makes sense to speak of them as moving away from salvation. This is the only way to reconcile the fact that some men lose their salvation (1 Tim 1:18-20) but to all of them God will still say “depart from Me, for I never knew you.”
Verdict: Tie. Both seem to be pretty good to me. I think the edge goes to the paedo, but both are solid answers.
Point 7 – Passive/Active Participation in Baptism
Issue: 1 Peter 3:21 says baptism now saves you, but 1 Cor 1:14 indicates baptism is not the primary idea in salvation. Further, Peter seems to indicate Baptism is something you submit to passively (Acts 2:38) rather than something you engage in. How do we reconcile this?
Credo: Baptism saves us by being an appeal to a good conscience, but it is not the driving force in salvation (that’s faith). 1 Peter 3:21 indicates that baptism is fundamentally an appeal to God for a clean conscience, which is exactly what we say baptism is.
Paedo: Baptism is spoken of in the passive sense by Peter in Acts because it’s the sign that belongs to the church to put on its people, not a sign people proclaim to the church. It’s spoken of as being equal to salvation by Peter in 1 Peter because without God’s promise and righteousness we cannot be saved. At the same time it’s spoken of as unequal to the blood of Christ sacrificed on our behalf because it is unequal in that respect.
Verdict: This is another close one that seems to fall in favor of the paedo.
Point 8 – Baptism Means ‘Immersion’
Issue: If Baptism is identical to immersion then how were the Israelites baptized into Moses when they crossed the Red Sea (1 Cor 10:2)? And how was Jesus referring to crucifixion when He used the word baptism (Matt 20:23)?
Credo: Baptism still means ‘to dip’. Jesus was plunged or dropped into suffering, and likewise the children of Israel were immersed into Moses.
Paedo: Baptism more nearly means ‘to wash; to pour,’ as much as ‘to dip’. Hebrews 9:10 speaks of various baptisms, with the reference in Numbers 19:17-18 being sprinkling. Further, the LXX translates “affrighted” in Isaiah 21:4 as “baptize”, which is what Jesus was quoting from in Matt 20:23.
Verdict: Tie. In fairness, I’m more interested in who is a candidate for baptism more than what is the proper mode of baptism.
Point 9 – Jesus Baptized His Disciples
Issue: Why did Jesus baptize his disciples in John 3:22 and not sooner? Or later? Why do the disciples turn around and immediately baptize the crowds that came to them (John 3:26, 4:2) rather than wait until their lives bore fruit to God?
Credo: The disciples were not baptized until John 3 because they didn't have enough information to make their faith valid until that point. They then turned around and baptized the crowd on profession of faith because Jesus instructed them to do so.
Paedo: if the credos are right then the disciples themselves should have been baptized sooner, since Nathan was a genuine professing believer since John 1:49-50. He wasn’t baptized because baptism pictures the objective work of Christ, and that wasn’t revealed until chapter 3. As soon as the discourse with Nicodemus reveals Jesus to be the center of the Old Testament, the one who’d be lifted up to give healing and salvation to those who looked on in faith, He takes His disciples to the river and baptizes them.
Verdict: Paedo wins a small victory, by a narrow margin. The credo might instead say Jesus was giving a baptism for ministry readiness (like how Levites were commissioned at age 30), or His was a baptism of repentance. Sure it’s a little strange to say that the Lords baptism was the same as Johns, or that baptism is a sign of commission, but it works after a fashion. Nonetheless, the paedo understanding is a slightly better fit.
Let’s step back and weigh how each side has done so far. The credo answers have been good, and there’s nothing to indicate any kind of systemic failure in them, while the paedo answers have also been good and have consistently provided a valid working framework for understanding the Scriptures. My hope in doing this was that one side would prove to be a clear winner, but so far it’s not panned out that way.
While the paedo system is fitting the data slightly better, there’s really nothing to cause me to give up being a credo-baptist, even though the ontological argument for paedo baptism is still bothering me (as it was the thing that drove me to do this work in the first place). But we’re not done yet. Let’s now turn to what seems to be the foundational issue: the presence or absence of a discontinuity between the Old and New Testaments.
