63. We think, beloved sons, that we cannot reinforce this fatherly exhortation of ours and bring it to an end more fittingly than by these admonitions of the same Apostle of the Gentiles: "Be on the watch, stand firm in the faith, play the man, be full of courage."³⁰ "Obey those who have charge of you,"³¹ your bishops and priests, when they give you instructions for your salvation and in accordance with the prescriptions of the Church. Offer active resistance to all those who in any way whatever scheme against your faith. Be "eager to preserve that unity the Spirit gives you, whose bond is peace. You are one body, with a single Spirit; each of you, when he was called, called in the same hope."³² In the midst of every kind of sorrow and affliction remember "that the sufferings of this time are not worthy to be compared to the glory to come that shall be revealed in us."³³ "But the Lord keeps faith with us; he will strengthen you, and keep you from all harm."³⁴
