70 Part One and the Son is adored and glorified” (Nicene Creed). 264 “The Holy Spirit proceeds from the Father as the first principle and, by the eternal gift of this to the Son, from the communion of both the Father and the Son” (St. Augustine, De Trin. 15, 26, 47: PL 42:1095). 265 By the grace of Baptism “in the name of the Father and of the Son and of the Holy Spirit,” we are called to share in the life of the Blessed Trinity, here on earth in the obscurity of faith, and after death in eternal light (Cf. Paul VI, CPG § 9). 266 “Now this is the Catholic faith: We worship one God in the Trinity and the Trinity in unity, without either confusing the persons or dividing the substance; for the person of the Father is one, the Son’s is another, the Holy Spirit’s another; but the Godhead of the Father, Son, and Holy Spirit is one, their glory equal, their majesty coeternal” (Athanasian Creed; DS 75; ND 16). 267 Inseparable in what they are, the divine persons are also inseparable in what they do. But within the single divine operation each shows forth what is proper to him in the Trinity, especially in the divine missions of the Son’s Incarnation and the gift of the Holy Spirit.
