Even the relationship with the created universe and human activity aimed at tending it and transforming it, activity which is daily endangered by man's pride and his inordinate self-love, must be purified and perfected by the cross and resurrection of Christ. “Redeemed by Christ and made a new creature by the Holy Spirit, man can, indeed he must, love the things of God's creation: it is from God that he has received them, and it is as flowing from God's hand that he looks upon them and reveres them. Man thanks his divine benefactor for all these things, he uses them and enjoys them in a spirit of poverty and freedom. Thus he is brought to a true possession of the world, as having nothing yet possessing everything: ‘All [things] are yours; and you are Christ's; and Christ is God's' (1 Cor 3:22-23)”⁴⁷ Second Vatican Ecumenical Council, Pastoral Constitution Gaudium et Spes, 37: AAS 58AAS — Acta Apostolicae Sedis (official gazette of the Holy See)Volume 58 (1966) at vatican.va — scanned PDF (1966), 1055..
