31 Faith in Christ the Redeemer, while it illuminates from within the nature of development, also guides us in the task of collaboration. In the Letter of St. Paul to the Colossians, we read that Christ is "the first-born of all creation," and that "all things were created through him" and for him (1:15-16). In fact, "all things hold together in him," since "in him all the fullness of God was pleased to dwell, and through him to reconcile to himself all things" (v. 20). A part of this divine plan, which begins from eternity in Christ, the perfect "image" of the Father, and which culminates in him, "the firstborn from the dead" (v. 18), is our own history, marked by our personal and collective effort to raise up the human condition and to overcome the obstacles which are continually arising along our way. It thus prepares us to share in the fullness which "dwells in the Lord" and which he communicates "to his body, which is the Church" (v. 18; cf. Eph 1:22-23). At the same time sin, which is always attempting to trap us and which jeopardizes our human achievements, is conquered and redeemed by the "reconciliation" accomplished by Christ (cf. Col 1:20). Here the perspectives widen. The dream of "unlimited progress" reappears, radically transformed by the new outlook created by Christian faith, assuring us that progress is possible only because God the Father has decided from the beginning to make man a sharer of his glory in Jesus Christ risen from the dead, in whom "we have redemption through his blood...the forgiveness of our trespasses" (Eph 1:7). In him God wished to conquer sin and make it serve our greater good, which infinitely surpasses what progress could achieve. We can say therefore - as we struggle amidst the obscurities and deficiencies of underdevelopment and superdevelopment - that one day this corruptible body will put on incorruptibility, this mortal body immortality (cf. 1 Cor 15:54), when the Lord "delivers the Kingdom to God the Father" (v. 24) and all the works and actions that are worthy of man will be redeemed. Furthermore, the concept of faith makes quite clear the reasons which impel the Church to concern herself with the problems of development, to consider them a duty of her pastoral ministry, and to urge all to think about the nature and characteristics of authentic human development. Through her commitment she desires, on the one hand, to place herself at the service of the divine plan which is meant to order all things to the fullness which dwells in Christ (cf. Col 1:19) and which he communicated to his body; and on the other hand she desires to respond to her fundamental vocation of being a "sacrament," that is to say "a sign and instrument of intimate union with God and of the unity of the whole human race." Some Fathers of the Church were inspired by this idea to develop in original ways a concept of the meaning of history and of human work, directed towards a goal which surpasses this meaning and which is always defined by its relationship to the work of Christ. In other words, one can find in the teaching of the Fathers an optimistic vision of history and work, that is to say of the perennial value of authentic human achievements, inasmuch as they are redeemed by Christ and destined for the promised Kingdom. Thus, part of the teaching and most ancient practice of the Church is her conviction that she is obliged by her vocation - she herself, her ministers and each of her members - to relieve the misery of the suffering, both far and near, not only out of her "abundance" but also out of her "necessities." Faced by cases of need, one cannot ignore them in favor of superfluous church ornaments and costly furnishings for divine worship; on the contrary it could be obligatory to sell these goods in order to provide food, drink, clothing and shelter for those who lack these things. As has been already noted, here we are shown a "hierarchy of values" - in the framework of the right to property - between"having" and "being," especially when the "having" of a few can be to the detriment of the "being" of many others. In his Encyclical Pope Paul VI stands in the line of this teaching, taking his inspiration from the Pastoral Constitution Gaudium et Spes . For my own part, I wish to insist once more on the seriousness and urgency of that teaching, and I ask the Lord to give all Christians the strength to put it faithfully into practice.
