The branches of the tree, ordained, lay, and consecrated, provide a network of supportive relationships ordered to build up the Body of Christ in love. "As all the members of the human body, though they are many, form one body, so also are the faithful in Christ (cf. 1 Cor.12:12). Also, in the building up of Christ's body there is engaged a diversity of members and functions. There is only one Spirit who, according to his own richness and the needs of the ministries, gives his different gifts for the welfare of the Church (cf. 1 Cor. 12:1-11)." (LG 7 ¶ 3)
