May The Paedobaptist Fairly Appeal To Matthew 19:13–15?

It was a wonderful day yesterday at Escondido URC. In the morning we had two baptisms, one of an adult convert who had never been baptized. So, like the adult baptisms we see in Acts, he received the sacrament, sign, and seal of baptism as a sign of his admission to the Christ-confessing covenant community. My Baptist friends rejoice with us. We also, however, baptized the infant of professing believers. We did so because we are convinced from God’s Word that is what God commands. The pattern begins in Genesis 17 and continues to the book of Acts (2:38–39; ch. 16 [all]). In his sermon our pastor, Chris Gordon, argued for the propriety of infant baptism on the basis of Matthew 19:13–15. Was he right to do so? Continue reading →

Paul’s Twofold Citizenship And Ours

The Logic Of Fruit As Evidence

The charge made by Rome and the Anabaptists, among others, was that the evangelical doctrine of salvation sola gratia, sola fide would make Christians cold and careless about their sanctification. The Reformed churches refuted that charge by arguing that the same grace by which we have been given new life also produces faith and it is “impossible for this holy faith to be unfruitful.” True faith is God’s gift. It unites us to the risen and ascended Christ who, by his Spirit, works in us conformity to himself and to his moral will. This is how we understand “faith working through love” (Gal 5:6). Rome, remember, turned “faith working through love” into “faith formed by love” (on this see part 1). In response, Calvin wrote on Galatians 5:6, “When you are engaged in discussing the question of justification, beware of allowing any mention to be made of love or of works, but resolutely adhere to the exclusive particle.” Continue reading →
