1 Corinthians 5/2 Corinthians 2 seems to be a powerful argument against rebaptism of those who repent after excommunication. There might be a desire on the part of the one being re-admitted into membership to say that his previous confession was obviously defective, thus the need for rebaptism, but that easy out should be avoided. Instead, the hard work of repentance and reconciliation should be pursued.
Maybe that’s because most sensible Baptists get that it’s an obviously unbiblical practice. Baptists are so diverse you don’t have to look very far for bad Baptist theology or practice. Rather like shooting fish in a barrel. Fortunately Presbyterians are a much tighter group when it comes to policing their own variances in doctrine and practice (wink wink)!
In all seriousness, this is why understanding the two divergent streams of Baptist theology is so important. There is a confessional stream that directly descends from the Magisterial Reformation. Then there is the anabaptist/revivalistic stream that has almost always identified itself against the reformed tradition. Add in that there are plenty like me who’ve switched streams and are trying to pursue not just a pure church but a healthy and historically reformed church.
I think this is key, and it seems to be to be one of the main battlegrounds of our day. The error of ‘justificationism’ (if I can coin a term) is the key liberalism we face at the the present time. [Historical note: classical reformed theology sees regeneration and sanctification as virtually synonymous. Regeneration generally refers to the Spirit’s work in sanctification, and sanctification refers to the believer’s responsibility in regeneration.]
The lack of sanctification is especially sad, because a lack of assurance seems endemic in our day. WCF 16 is clear that sanctification drives assurance. Want to feel closer to God? Pursue conformity to Christ.
