Pius XII's Mystici Corporis Christi (On the Mystical Body of Christ)
Encyclical of Pope Pius XII on the Mystical Body of Christ, June 29, 1943
Sections 1-5
To Our Venerable Brethren, Patriarchs, Primates, Archbishops, Bishops, and other Local Ordinaries enjoying Peace and Communion with the Apostolic See.
Venerable Brethren, Health and Apostolic Benediction.
The doctrine of the Mystical Body of Christ, which is the Church, was first taught us by the Redeemer Himself. Illustrating as it does the great and inestimable privilege of our intimate union with so exalted a Head, this doctrine by its sublime dignity invites all those who are drawn by the Holy Spirit to study it, and gives them, in the truths of which it proposes to the mind, a strong incentive to the performance of such good works as are conformable to its teaching. For this reason, We deem it fitting to speak to you on this subject through this Encyclical Letter, developing and explaining above all, those points which concern the Church Militant. To this We are urged not only by the surpassing grandeur of the subject but also by the circumstances of the present time.
2. For We intend to speak of the riches stored up in this Church which Christ purchased with His own Blood, and whose members glory in a thorn crowned Head. The fact that they thus glory is a striking proof that the greatest joy and exaltation are born only of suffering, and hence that we should rejoice if we partake of the sufferings of Christ, that when His glory shall be revealed we may also be glad with exceeding joy.
3. From the outset it should be noted that the society established by the Redeemer of the human race resembles its divine Founder who was persecuted, calumniated and tortured by those very men whom He had undertaken to save. We do not deny, rather from a heart filled with gratitude to God We admit, that even in our turbulent times there are many who, though outside the fold of Jesus Christ, look to the Church as the only haven of salvation; but We are also aware that the Church of God not only is despised and hated maliciously by those who shut their eyes to the light of Christian wisdom and miserably return to the teachings, customs and practices of ancient paganism, but is ignored, neglected, and even at times looked upon as irksome by many Christians who are allured by specious error or caught in the meshes of the world's corruption. In obedience, therefore, Venerable Brethren, to the voice of Our conscience and in compliance with the wishes of many, We will set forth before the eyes of all and extol the beauty, the praises, and the glory of Mother Church to whom, after God, we owe everything.
4. And it is to be hoped that Our instructions and exhortations will bring forth abundant fruit in the souls of the faithful in the present circumstances. For We know that if all the sorrows and calamities of these stormy times, by which countless multitudes are being sorely tried, are accepted from God's hands with calm submission, they naturally lift souls above the passing things of earth to those of heaven that abide forever, and arouse a certain secret thirst and intense desire for spiritual things. Thus, urged by the Holy Spirit, men are moved, and, as it were, impelled to seek the Kingdom of God with greater diligence; for the more they are detached from the vanities of this world and from inordinate love of temporal things, the more apt they will be to perceive the light of heavenly mysteries. But the vanity and emptiness of earthly things are more manifest today than perhaps at any other period, when Kingdoms and States are crumbling, when enormous quantities of goods and all kinds of wealth are being sunk in the depths of the sea, and cities, towns and fertile fields are strewn with massive ruins and defiled with the blood of brothers.
5. Moreover, We trust that Our exposition of the doctrine of the Mystical Body of Christ will be acceptable and useful to those also who are without the fold of the Church, not only because their good will towards the Church seems to grow from day to day, but also because, while before their eyes nation rises up against nation, kingdom against kingdom and discord is sown everywhere together with the seeds of envy and hatred, if they turn their gaze to the Church, if they contemplate her divinely-given unity--by which all men of every race are united to Christ in the bond of brotherhood they will be forced to admire this fellowship in charity, and with the guidance and assistance of divine grace will long to share in the same union and charity.
