Thank you.
As a Baptist, I will never die on the hill of paedobaptism. I am simply pointing out that the person seeking membership has been baptized into the covenant as a child and now has confirmed his faith. Does God require a second baptism in order to be obedient to the ordinance of baptism? I don't see any scripture that would make such an argument for a second baptism. I also don't find an explicit argument for infant baptism. So, it seems that both sides are arguing from a normative procedure rather than a regulative position.
The issue is that you believe that paedobaptism is legitimate baptism, that the infants are actually in the covenant of grace. This is opposed to Baptist beliefs. Are the unrepentant, unregenerate, those without faith part of the Covernant of Grace? Should the unrepentant, unregenerate and those without faith be given the covenant sign? Baptists say No! The Presbyterians say yes.
The Covenant of Grace is the New Covenant, the Covenant which was inaugerated by the shedding of the precious blood of Chrsit. Only those who are in Christ are in the Covenant. There is no second baptism as you keep stating, so of course you won't find scripture arguing for that.
Baptism is a hill worth dying over.
No one is arguing the narrative of people who were baptized in the Bible.
Is there a prescriptive requirement that only someone who confesses salvation can be baptized? Do any of the verses you quoted make that prescription? You imply this, but is it specifically prescriptive?
I say that we must extend grace in this matter. If a person exhibits genuine salvation and was genuinely baptized, even as an infant, that person has fulfilled the ordinance of our King. I would admit that person into membership in the local church without hesitation.
Why do you believe that faith and repentance is irrelevant to the legitimacy of Baptism? Presbyterians seperate salvation with the Church (which is the body of Christ), thus unregenerate, unsaved peope are in and are the body of Christ. I would say that scripture is clear about who is in the covenant and thus only those in covenant should recieve the covenant sign.
Are there any examples where baptism was given without a profession of faith? Where do you find even a hint that unbelieving infants should or are baptised in scripture? Where in scripture does it teach that circumcision equals baptism? Presbyterians needed to make a baptism the same substance as circumcision because they did not have any teaching from the new which justified their theology.
If a infant was "baptised" but then rejected the Church/the faith but then a few years later was converted. Would this person need to be "re-baptised"?
Have you studied Reformed Baptist theology? because by the sound of it you've read alot of presbyterian theology.
