2 Timothy 1:8

There is nothing worse than that man should measure and judge of divine things by human reasonings. For thus he will fall from that rock a vast distance, and be deprived of the light. For if he who wishes with human eyes to apprehend the rays of the sun will not only not apprehend them, but, besides this failure, will sustain great injury; so, but in a higher degree, is he in a way to suffer this, and abusing the gift of God, who would by human reasonings gaze intently on that Light. Observe accordingly how Marcion, and Manes, and Valentinus, and others who introduced their heresies and pernicious doctrines into the Church of God, measuring divine things by human reasonings, became ashamed of the Divine economy. Yet it was not a subject for shame, but rather for glorying; I speak of the Cross of Christ. For there is not so great a sign of the love of God for mankind, not heaven, nor sea, nor earth, nor the creation of all things out of nothing, nor all else beside, as the Cross. Hence it is the boast of Paul, "God forbid that I should glory, save in the Cross of our Lord Jesus Christ." (Gal. vi. 14.) But natural men, and those who attribute to God no more than to human beings, stumble, and become ashamed. Wherefore Paul from the first exhorts his disciple, and through him all others, in these words: "Be not thou ashamed of the testimony of our Lord," that is, "Be not ashamed, that thou preachest One that was crucified, but rather glory in it." For in themselves death and imprisonment and chains are matters of shame and reproach. But when the cause is added before us, and the mystery viewed aright, they will appear full of dignity, and matter for boasting. For it was that death which saved the world, when it was perishing. That death connected earth with heaven, that death destroyed the power of the devil, and made men angels, and sons of God: that death raised our nature to the kingly throne. Those chains were the conversion of many. "Be not" therefore "ashamed," he says, "of the testimony of our Lord, nor of me His prisoner: but be thou partaker of the afflictions of the Gospel"; that is, though thou shouldest suffer the same things, be not thou ashamed. For that this is implied appears from what he said above; "God hath given us a spirit of power, and of love, and of a sound mind"; and by what follows, "Be thou partaker of the sufferings of the Gospel": not merely be not ashamed of them, but be not ashamed even to experience them. And he does not say, "Do not fear," but, the more to encourage him, "be not ashamed," as if there were no further danger, if he could overcome the shame. For shame is only then oppressive, when one is overcome by it. Be not therefore ashamed, if I, who raised the dead, who wrought miracles, who traversed the world, am now a prisoner. For I am imprisoned, not as a malefactor, but for the sake of Him who was crucified. If my Lord was not ashamed of the Cross, neither am I of chains. And with great propriety, when he exhorts him not to be ashamed, he reminds him of the Cross. If thou art not ashamed of the Cross, he means, neither be thou of chains; if our Lord and Master endured the Cross, much more should we chains. For he who is ashamed of what He endured, is ashamed of Him that was crucified. Now it is not on my own account that I bear these chains; therefore do not give way to human feelings, but bear thy part in these sufferings. "Be partaker of the afflictions of the Gospel." He says not this, as if the Gospel could suffer injury, but to excite his disciple to suffer for it.
