Here is a short summary statement of John Calvin’s argument for applying the sign of baptism to the children of Believers:
“Reason would tell us that baptism is rightly administered to babies. The Lord did not give circumcision long ago without making them (infants) partakers of everything represented by circumcision. He would have been deceiving his people with a sham, if he had reassured them with false signs. The idea is very shocking. He distinctly states that the circumcision of the infant is the seal of covenant promise. If the covenant remains firm and unmoved, this is just as relevant to the children of Christians today as it was to the children of the Jews under the Old Testament…The truth of baptism applies to infants, so why do we deny them the sign? The Lord himself formally admitted infants to his covenant, so what more do we need?”
John Calvin, Institutes of the christian religion, 4:16:5 (Beveridge Edition)
Most Reformed and Presbyterian families embrace Calvin’s way of thinking when it comes to our “Covenant Children.” We understand that God has given each child to the Christian family as a “heritage,” a “reward,” and a “blessing” (Ps. 127:3-5). And, that the sign and seal of the Old Testament–which was circumcision (Gen. 17:7-9; Rom. 4:11)–has now been replaced by baptism in the New Testament (Col. 2:11-12). Standing on the promises of the Covenant of Grace, Christian parents are solemnly tasked by Jesus Christ “to make disciples” of their children by “baptizing them in the name of the Father and of the Son and of the Holy Spirit” (Matt. 28:19). Lastly, they are instructed by the Apostle Paul to “bring them up in the discipline and instruction of the Lord” (Eph. 6:4; Matt. 28:20). This is serious business!
Therefore, it is imperative that Christian fathers and mothers embrace the promises of God for each one of their children (Ps. 78:1-8). Consider the Apostle Peter’s striking admonition to his fellow Jews on the day of Pentecost, “For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself” (Acts 2:39). In other words, those who follow Jesus Christ as His disciples are responsible by faith to entrust the spiritual awakening of their own children to God’s gracious work (John 3:3-5; Titus 3:5-7). We do this by presenting our “Covenant Children” for baptism and by instructing them in the truths of the Gospel as they mature.
