To a Thousand Generations: Infant Baptism - Covenant Mercy to the Children of God

by Douglas Wilson

So believing Jews continued to practice circumcision, which placed their sons into membership in a visible assembly of Christian saints—the Christian synagogue. But the Jews were also to be baptized. We know this because the New Israel, Jew and Gentile alike, had one Lord, one faith, one baptism (Eph. 4:5). When Peter preached to the Jews on the day of Pentecost, he told them that they needed to repent and be baptized, because the promise was for them and their children (Acts 2:39). So the believing Gentiles had baptism, while the believing Jews had circumcision and baptism. Circumcision was retained by the Jews, prohibited to the Gentiles as a spiritual requirement, and baptism was commanded of them both. Incidentally, we can see clearly in retrospect that baptism, being required of both Jew and Gentile, was intended by Christ to be the lasting sign of initiation into the church.
