ISB ~ Matthew 28 v19

Go therefore:Christ’s commission to evangelize kilkJ and catechize the world fulfills God’s covenant oath to Abraham that “all the nations” would be blessed (Gen 22:18; Gal 3:8). His outline for the Church’s mission is threefold: (1) Evangelizing all nations involves more than winning individuals; it entails the conversion of entire cultures. Every area of life must be brought under the Lordship of Christ and in line with the gospel. (2) The administration of the sacraments is essential to the Church’s mission and our response. [B]aptizing new converts is the first step in a long process of sanctification and participation in the life of the Church. (3) The transmission of all that Christ taught necessitates the assistance of the Holy Spirit, who guides the Church to proclaim the gospel infallibly (cf. Jn 14:26). See note on Jn 16:13.

• The Sacrament of Baptism incorporates Christians into the divine family of the Trinity as children of God (cf. Gal 3:26, 27). The single name of the Father, Son, and Spirit reveals the unity of God’s inner life and the oneness of his nature. This expression has become the normative baptismal formula for the Church (CCC 849, 1122, 1257). See note on Mt 3:11.
