From John Paul II, Salvifici doloris, On Christian Suffering
In the second reading this Sunday, St. Paul talks about suffering with and for Christ. To help understand this, the following is from St. John Paul II on the same theme.
Nevertheless, the Apostle’s experiences as a sharer in the sufferings of Christ go even further. In the Letter to the Colossians we read the words which constitute as it were the final stage of the spiritual journey in relation to suffering: “Now I rejoice in my sufferings for your sake, and in my flesh I complete what is lacking in Christ’s afflictions for the sake of his body, that is, the Church”. And in another Letter he asks his readers: “Do you not know that your bodies are members of Christ?”.
In the Paschal Mystery Christ began the union with man in the community of the Church. The mystery of the Church is expressed in this: that already in the act of Baptism, which brings about a configuration with Christ, and then through his Sacrifice—sacramentally through the Eucharist—the Church is continually being built up spiritually as the Body of Christ. In this Body, Christ wishes to be united with every individual, and in a special way he is united with those who suffer. The words quoted above from the Letter to the Colossians bear witness to the exceptional nature of this union. For, whoever suffers in union with Christ— just as the Apostle Paul bears his “tribulations” in union with Christ— not only receives from Christ that strength already referred to but also “completes” by his suffering “what is lacking in Christ’s afflictions”. This evangelical outlook especially highlights the truth concerning the creative character of suffering. The sufferings of Christ created the good of the world’s redemption. This good in itself is inexhaustible and infinite. No man can add anything to it. But at the same time, in the mystery of the Church as his Body, Christ has in a sense opened his own redemptive suffering to all human suffering. In so far as man becomes a sharer in Christ’s sufferings—in any part of the world and at any time in history—to that extent he in his own way completes the suffering through which Christ accomplished the Redemption of the world.
Does this mean that the Redemption achieved by Christ is not complete? No. It only means that the Redemption, accomplished through satisfactory love, remains always open to all love expressed in human suffering. In this dimension—the dimension of love—the Redemption which has already been completely accomplished is, in a certain sense, constantly being accomplished. Christ achieved the Redemption completely and to the very limits but at the same time he did not bring it to a close. In this redemptive suffering, through which the Redemption of the world was accomplished, Christ opened himself from the beginning to every human suffering and constantly does so. Yes, it seems to be part of the very essence of Christ’s redemptive suffering that this suffering requires to be unceasingly completed.
Thus, with this openness to every human suffering, Christ has accomplished the world’s Redemption through his own suffering. For, at the same time, this Redemption, even though it was completely achieved by Christ’s suffering, lives on and in its own special way develops in the history of man. It lives and develops as the body of Christ, the Church, and in this dimension every human suffering, by reason of the loving union with Christ, completes the suffering of Christ. It completes that suffering just as the Church completes the redemptive work of Christ. The mystery of the Church—that body which completes in itself also Christ’s crucified and risen body—indicates at the same time the space or context in which human sufferings complete the sufferings of Christ. Only within this radius and dimension of the Church as the Body of Christ, which continually develops in space and time, can one think and speak of “what is lacking” in the sufferings of Christ. The Apostle, in fact, makes this clear when he writes of “completing what is lacking in Christ’s afflictions for the sake of his body, that is, the Church”.
It is precisely the Church, which ceaselessly draws on the infinite resources of the Redemption, introducing it into the life of humanity, which is the dimension in which the redemptive suffering of Christ can be constantly completed by the suffering of man. This also highlights the divine and human nature of the Church. Suffering seems in some way to share in the characteristics of this nature. And for this reason suffering also has a special value in the eyes of the Church. It is something good, before which the Church bows down in reverence with all the depth of her faith in the Redemption. She likewise bows down with all the depth of that faith with which she embraces within herself the inexpressible mystery of the Body of Christ.
