1 Cor 12:13

12:13 all baptized . . . of one Spirit. The emphasis on the word “all” and the allusion to the sacraments recalls the similar description of the Israelites in 10:2–4 (notes). One of the truths signified and sealed by water baptism is the baptism of the Holy Spirit that incorporates believers into the one body of Christ. Baptism replaces circumcision as the sign of admission into God’s covenant (Col. 2:11–14). Similarly, partaking of the Lord’s Supper signifies our continued communion with Christ and His church (10:17; 11:29 note).
