38 We visualize the immense multitudes of Our faithful children, Our sons and daughters, for whom the sufferings of the Church in Germany and their own have left intact their devotion to the cause of God, their tender love for the Father of Christendom, their obedience to their pastors, their joyous resolution to remain ever faithful, happen what may, to the sacred inheritance of their ancestors. To all of them We send Our paternal greetings. And first to the members of those religious associations which, bravely and at the cost of untold sacrifices, have remained faithful to Christ, and have stood by the rights which a solemn treaty had guaranteed to the Church and to themselves according to the rules of loyalty and good faith.
