n nYouve been baptized. But do you understand what it means?n n nn nBaptism is the doorway into membership in the church. Its a public declaration of the washing away of our sin and the beginning of our new life in Christ. But the sacrament that is meant to unite us is often a spring of division instead.n n nn nAll Christians use water to baptize. All invoke the triune name. Beyond that, theres little consensus. Talk about baptism and youre immediately plunged into arguments. Whom should we baptize? What does baptism do? Why even do it at all?n n nn nPeter Leithart reunifies a church divided by baptism. He recovers the baptismal imagination of the Bible, explaining how baptism works according to Scripture. Then, in conversation with Christian tradition, he shows why baptism is something worth recovering and worth agreeing on.n
