Calvin interprets Titus 3:5 as a baptismal passage. Baptism is a sign and pledge of God’s mercy that signifies and pledges this mercy by ingrafting the baptized into the church: “The train of thought of the passage is this: ‘God saves us by his mercy and he has given us a symbol and pledge of this salvation by baptism, by admitting us into his Church and engrafting us into the Body of His Son.’”
