Baptism is the sacrament that initiates believers into the covenant of grace, symbolizing death, new life, and triumph in Christ. It represents the washing away of sin and the Spirit’s work in deliverance. The catechism links baptism to Christ’s death and resurrection, while 1 Peter connects it to the sprinkling of Christ’s blood, echoing Old Testament purification. Ultimately, baptism points to Christ’s redemptive work, calling believers to trust in Him rather than the sign itself.
