Georgia Baptist John Leadley Dagg wrote A Decisive Argument Against Infant Baptism: Furnished by One of Its Own Proof-texts. I haven't found this tract, but it is included in Tracts on Important Subjects (Charleston SC: Southern Baptist Publication Society, 1854). [Use the Google Search and look for "infant baptism".] Dagg's argument is based on I Corinthians 7:14: For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy. He shows that the unbelieving spouse and the unknowing child have the same sanctified relationship to the believer. "The church at Corinth was a Pedobaptist church, or it was not. If it was a Pedobaptist church, the argument of Paul was invalid; because it was based on the false assumption, that the children sealed with the seal of God's covenant, dedicated to Him in the holy rite of baptism, and admitted within the pale of the church, were in like circumstances with unbelieving and unbaptized adults, who were out of the covenant, and out of the church. But Paul did not use an invalid argument: therefore this church was not Pedobaptist; and the same must be true of all the churches planted by the Apostles, since they were, doubtless, all similarly organized." -- From A Decisive Argument Against Infant Baptism by J. L. Dagg What do you think of I Corinthians 7:14 in regard to infant baptism?
