Backus struggled with the issue of baptism, studied Scripture, rejected infant baptism, and was baptized by dipping on August 22, 1751. He set out to refute the anti-pedobaptist position by first turning to the Bible, and then to the claims of Baptist scholars in England that infant baptism was a corruption brought into the Christian church in the 2nd or 3rd century. What he found surprised him.
Next, Backus examined the Covenant Theology which lay at the heart of New England Puritanism. The relevance of this theology to Backus was mainly its effect on the church-state issue:
- First, “[T]he Jewish church was clearly a national church, a theocracy in which Moses and Aaron ruled together, and thus the Puritans were able to utilize the covenant theology to justify their ecclesiastical laws and their system of territorial parishes and religious taxes. Second, the covenant theology provided the Puritans with justifications for the Halfway Covenant, thus polluting the purity of the mystical body of Christ. And in the third place the covenant theology, by emphasizing that grace ran ‘through the loins of godly parents,’ that the baptized children of visible saints were somehow more likely than others to obtain salvation, thereby established a kind of hereditary spiritual aristocracy; it also undermined the sovereignty of God by implying that God was bound by this covenant to save certain persons rather than others. [Etc.]”
The Puritans supported the unity of the Abrahamic Covenant in Romans 11.17.
- “Here, the apostle Paul spoke of the Christian covenant as being grafted on to the Jewish covenant as a branch is grafted on to an olive tree, from whence the Puritans ‘argued the right of professors now to baptize their children, because the Jews circumcised theirs.’ This Backus rejected as misinterpretation. ‘The Jews were broken off thro’ unbelief, and the Gentiles were grafted in, and stand only by faith.’ Faith was essential to baptism. What Puritans stressed as organic continuity, Backus and the Baptists stressed as a complete break.”
Backus concluded that the Separates must explicitly reject the Covenant Theology, the whole conception of the corporate Christian state, which the Puritans had so painstakingly constructed in the wilderness of New England. Backus decided against infant baptism and was baptized. “[H]e rejected the Covenant Theology of the Puritans by arguing as the Baptists had long done that the Bible contained two covenants, the old Covenant of Works made with the Jews, and the Covenant of Grace made with those who believe in Christ….” “[T]he Puritans had confused the gospel of grace with the doctrine of works and transformed the gospel church of visible saints into a national church with a birthright membership.” “Backus and the Baptists stressed the discontinuity, the antithetical nature of the two, the complete and distinct break between the past and the present dispensations. That Americans were ready to grasp this new outlook after 1740 and to pursue it to its logical conclusions marks the real break with the Old World, the medieval mind and the Puritan ethos….”
