1 The firm purpose and desire which We resolved upon at the beginning of Our Pontificate to consecrate all the energy which the good Lord deigns to grant Us in the work of restoring all things in Christ, reawakens in Our heart a great trust in the all powerful grace of God. Without that grace We can neither plan nor undertake anything great or fruitful for the good of souls here below. At the same time, however, We feel more than ever the need of being upheld unanimously and constantly in this venture both by you, Venerable Brethren, called to participate in Our pastoral office, as well as by all the clergy and faithful committed to your care. Truly, all of us in the Church are called to form that unique Body, whose Head is Christ; "closely joined," as the Apostle Paul teaches, "and knit together through every joint of the system according to the functioning in due measure of each single part." In such a way the Body increases and gradually perfects itself in the bond of charity. Now, if in this work of "building up the body of Christ" it is Our primary duty to teach, to point out the correct way to follow, to propose the means to be used, to admonish and paternally exhort, it is also the duty of Our beloved children, dispersed throughout the world, to heed Our words, to carry them out first of all in their own lives, and to aid in their effective fulfillment in others, each one according to the grace of God received, according to his state in life and duties, and according to the zeal which inflames his heart.
