All the Old Covenant prefigurations find their fulfillment in Christ Jesus. He begins his public life after having himself baptized by St. John the Baptist in the Jordan. Cf. Mt 3:13. After his resurrection Christ gives this mission to his apostles: "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you." Mt 28:19-20; cf. Mk 16:15-16.
