Infant Baptism vs. Believer's Baptism
Last updated: 2026-04-10
The case for infant baptism within the broader Reformed tradition centers on the continuity between circumcision in the Old Testament and baptism in the New Testament as signs of the same covenant of grace. While Reformed and Presbyterian traditions argue that infants of believing parents are entitled to the covenant sign, many Particular Baptists hold that baptism is the sign of the new covenant reserved for those who personally profess faith in Christ.
📖 Covenantal Continuity
In the Reformed and Presbyterian understanding, as articulated in the Heidelberg Catechism Q.74 and Calvin’s Institutes of the Christian Religion Ch.16, baptism is viewed as the successor to circumcision. Just as children under the old covenant were initiated into the community of God's people through circumcision, so too are the children of believers considered to be included in the covenant of grace. It is argued that the promise of redemption is extended to them no less than to adults, and thus the outward sign is applied to testify to their inclusion in the visible church.

🌊 A Baptist Perspective
As a Particular Baptist, my understanding is grounded in the conviction that the new covenant differs significantly from the old. While the old covenant included the natural descendants of Israel, the new covenant is constituted by those who personally know the Lord through faith, as promised in Jeremiah 31:31-34. Therefore, the 1689 LBCF Ch.29 §2 maintains that baptism is an ordinance of the New Testament to be administered only to those who do actually profess repentance towards God, faith in, and obedience to our Lord Jesus Christ. Scripture states: "For by one Spirit were we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and were all made to drink of one Spirit." (1 Corinthians 12:13).

Credobaptists (Baptists) argue that baptism is the sign of the New Covenant, which is explicitly established upon the promise of faith, thus requiring a personal profession. While the two sides differ sharply on the subjects of baptism, they agree on the necessity of faith for salvation and the importance of the sacraments as divine signs of God’s grace.
📖 The Credobaptist Perspective
Credobaptists, or 'believer-baptists,' argue that the New Covenant differs fundamentally from the Old in its administration. While the Old Covenant included the physical seed of Abraham by birth, the New Covenant is characterized by the internal work of the Spirit, where all who are in the covenant know the Lord personally (Hebrews 8:10-12). Consequently, the 1689 London Baptist Confession holds that baptism is to be administered only to those who 'do actually profess repentance towards God, faith in, and obedience to, our Lord Jesus Christ' (1689 LBCF Ch.28 §1). Credobaptists maintain that the New Covenant is a community of believers, not a mixture of believers and their natural offspring, and that baptism is the symbol of this union with Christ in his death and resurrection.

🤝 Areas of Theological Agreement
Despite the disagreement regarding the subjects of baptism, both parties stand firmly on the bedrock of the gospel. Both agree that salvation is by grace alone through faith alone, not by the ordinance of baptism itself (Ephesians 2:8-9). Furthermore, both traditions view baptism as a holy, divine institution rather than a mere human invention or empty symbol. They agree that baptism is a means of grace, a public testimony of the believer's identity in Christ, and a command to be obeyed by the Church. Both maintain that faith is the instrumental cause of justification and that sacraments serve to confirm, seal, and exhibit the promises of the gospel to the believer (1689 LBCF Ch.14 §1).
