Matthew 6, 33 + CSDC and CV

(CV 9c) Fidelity to man requires fidelity to the truth, which alone is the guarantee of freedom (cf. Jn 8:32) and of the possibility of integral human development. For this reason the Church searches for truth, proclaims it tirelessly and recognizes it wherever it is manifested. This mission of truth is something that the Church can never renounce. Her social doctrine is a particular dimension of this proclamation: it is a service to the truth which sets us free. Open to the truth, from whichever branch of knowledge it comes, the Church's social doctrine receives it, assembles into a unity the fragments in which it is often found, and mediates it within the constantly changing life-patterns of the society of peoples and nations [12].

With her social doctrine the Church is rigorously faithful to her mission

CSDC 64a. With her social doctrine not only does the Church not stray from her mission but she is rigorously faithful to it. The redemption wrought by Christ and entrusted to the saving mission of the Church is certainly of the supernatural order. This dimension is not a delimitation of salvation but rather an integral expression of it [82].

Paul VI, Apostolic Exhortation Evangelii Nuntiandi 9, 30: AAS 68 (1976), 10-11; John Paul II, Address to the Third General Conference of Latin American Bishops, Puebla, Mexico (28 January 1979), III/4-7: AAS 71 (1979), 199-204; Congregation for the Doctrine of the Faith, Instruction Libertatis Conscientia, 63-64, 80:  AAS 79 (1987), 581-582, 590-591.

(Mt 6, 33) Justice, brotherhood, solidarity and sharing

[33] But seek first the kingdom (of God) and his righteousness, and all these things will be given you besides.

CSDC 325. Jesus takes up the entire Old Testament tradition even with regard to economic goods, wealth and poverty, and he gives them great clarity and fullness (cf. Mt 6:24, 13:22; Lk 6:20-24, 12:15-21; Rom 14:6-8; 1 Tim 4:4). Through the gift of his Spirit and the conversion of hearts, he comes to establish the “Kingdom of God”, so that a new manner of social life is made possible, in justice, brotherhood, solidarity and sharing. The Kingdom inaugurated by Christ perfects the original goodness of the created order and of human activity, which were compromised by sin. Freed from evil and being placed once more in communion with God, man is able to continue the work of Jesus, with the help of his Spirit. In this, man is called to render justice to the poor, releasing the oppressed, consoling the afflicted, actively seeking a new social order in which adequate solutions to material poverty are offered and in which the forces thwarting the attempts of the weakest to free themselves from conditions of misery and slavery are more effectively controlled. When this happens, the Kingdom of God is already present on this earth, although it is not of the earth. It is in this Kingdom that the promises of the Prophets find final fulfilment.
