Eph 1, 23 Which is his body

(Eph 1, 23) Which is his body

[23] which is his body, the fullness of the one who fills all things in every way.

(CCC 830) The word "catholic" means "universal," in the sense of "according to the totality" or "in keeping with the whole." The Church is catholic in a double sense: First, the Church is catholic because Christ is present in her. "Where there is Christ Jesus, there is the Catholic Church" (St. Ignatius of Antioch, Ad Smyrn. 8, 2: Apostolic Fathers, II/2, 311). In her subsists the fullness of Christ's body united with its head; this implies that she receives from him "the fullness of the means of salvation" (UR 3; AG 6; Eph 1:22-23) which he has willed: correct and complete confession of faith, full sacramental life, and ordained ministry in apostolic succession. The Church was, in this fundamental sense, catholic on the day of Pentecost (Cf. AG 4) and will always be so until the day of the Parousia. (CCC 831) Secondly, the Church is catholic because she has been sent out by Christ on a mission to the whole of the human race (Cf. Mt 28:19): All men are called to belong to the new People of God. This People, therefore, while remaining one and only one, is to be spread throughout the whole world and to all ages in order that the design of God's will may be fulfilled: he made human nature one in the beginning and has decreed that all his children who were scattered should be finally gathered together as one.... The character of universality which adorns the People of God is a gift from the Lord himself whereby the Catholic Church ceaselessly and efficaciously seeks for the return of all humanity and all its goods, under Christ the Head in the unity of his Spirit (LG 13 §§ 1-2; cf. Jn 11:52). (CCC 2044) The fidelity of the baptized is a primordial condition for the proclamation of the Gospel and for the Church's mission in the world. In order that the message of salvation can show the power of its truth and radiance before men, it must be authenticated by the witness of the life of Christians. "The witness of a Christian life and good works done in a supernatural spirit have great power to draw men to the faith and to God" (AA 6 § 2).
