62 Lastly we address all of you, Catholics of the Ruthenian Church. We share your sorrows and afflictions with a father's heart. We know that grievous snares are being set for your faith. There seems ground for fear that in the near future still greater hardships will befall those who refuse to betray their sacred religious allegiance. For that reason we even now exhort you in the Lord, beloved sons, to be terrified by no menaces or injuries, to be moved by no danger of exile or risk even of life ever to abjure your faith and your fidelity to Mother Church. That treasure is involved which is hidden in a field and the man who finds it "hides it again, and now, for the joy it gives him is going home to sell all that he has and buy that field." Remember, too, what the Divine Redeemer Himself said in the Gospel: "He is not worthy of me, that loves father or mother more; he is not worthy of me, that loves son or daughter more; he is not worthy of me, that does not take up his cross and follow me. He who secures his own life will lose it; it is the man who loses his life for my sake that will secure it." To this divine pronouncement we will add the words of the Apostle of the Gentiles: "It is well said, We are to share his life, because we have shared his death; if we endure, we shall reign with him, if we disown him, he in his turn will disown us. If we play him false, he remains true to his word; he cannot disown himself."
