Ambrosiaster : Paul is saying that people who long for heavenly things despise the things of this world, because in comparison with what they want, these things are nothing. — COMMENTARY ON PAUL'S EPISTLES Caesarius of Arles : If you seek temporal things, you pray publicly and with your door open. If you ask for eternal things, your prayer is secret because you long to receive not the things which are seen but those which are not seen. — SERMON 146.3 Clement of Alexandria : Head-dresses and varieties of head-dresses, and elaborate braidings, and infinite modes of dressing the hair, and costly specimens of mirrors, in which they arrange their costume,-hunting after those that, like silly children, are crazy about their figures,-are characteristic of women who have lost all sense of shame. If any one were to call these courtesans, he would make no mistake, for they turn their faces into masks. But us the Word enjoins "to look not on the things that are seen, but the things that are not seen; for the things that are seen are temporal, but the things that are not seen are eternal." — The Instructor Book 3 Clement of Alexandria : More grievous and painful is this persecution, which arises from within, which is ever with a man, and which the persecuted cannot escape; for he carries the enemy about everywhere in himself. Thus also burning which attacks from without works trial, but that from within produces death. War also made on one is easily put an end to, but that which is in the soul continues till death. With such persecution, if you have worldly wealth, if you have brothers allied by blood and other pledges, abandon the whole wealth of these which leads to evil; procure peace for yourself, free yourself from protracted persecutions; turn from them to the Gospel; choose before all the Saviour and Advocate and Paraclete of your soul, the Prince of life. "For the things which are seen are temporary; but the things which are not seen are eternal." And in the present time are things evanescent and insecure, but in that to come is eternal life. — Who is the Rich Man that Shall Be Saved? Ignatius of Antioch : Ye have never envied any one; ye have taught others. Now I desire that those things may be confirmed [by your conduct], which in your instructions ye enjoin [on others]. Only request in my behalf both inward and outward strength, that I may not only speak, but [truly] will; and that I may not merely be called a Christian, but really be found to be one. For if I be truly found [a Christian], I may also be called one, and be then deemed faithful, when I shall no longer appear to the world. Nothing visible is eternal. "For the things which are seen are temporal, but the things which are not seen are eternal." For our God, Jesus Christ, now that He is with the Father, is all the more revealed [in His glory]. Christianity is not a thing of silence only, but also of [manifest] greatness. — Epistle of Ignatius to the Romans John Chrysostom : Consider, dearly beloved, that life's troubles, even if distressing, are still of short duration, whereas the good things that will come to us in the next life are eternal and everlasting. "What we see is passing," Scripture says, "but what is not seen is everlasting." Accordingly, let us endure what is passing without complaint and not desist from virtue's struggle so that we may enjoy the good things that are eternal and last forever. — HOMILIES ON Genesis 25.24 John Chrysostom : Far from being surprised or troubled, let us endure developments with complete fortitude and endurance, having regard not to the distress but to the gain accruing to us from it. This transaction, you see, is spiritual. People intent on making money and being involved in a transaction of this life would succeed in increasing their wealth in no other way than by being exposed to great danger on land and at sea (they must, after all, put up with the onset of brigands and wiles of pirates), and yet they are ready to accept everything with great enthusiasm, having no sense of hardship through the expectation of gain. In just the same way must we keep our mind on the wealth and spiritual riches accruing to us from this. We must rejoice and be glad, considering not what can be seen but what cannot be seen, as Paul's exhortation goes, "not considering what can be seen." — HOMILIES ON Genesis 63.20 John Chrysostom : And, to show you that he was as it were in solitude, and so looked upon the things present, hear himself saying, "While we look not at the things which are seen, but at the things which are not seen." What sayest thou? Answer me. And yet what thou sayest is the contrary; thou seest the things invisible, and the visible thou seest not. Such eyes as thou hadst gotten, such are the eyes which are given by Christ: for as these bodily eyes see indeed the things that are seen, but things unseen they see not: so those heavenly eyes do the contrary: no one that beholds the invisible things, beholds the visible: no one beholding the things seen, beholds the invisible. Or is not this the case with us also? For when having turned our mind inwards we think of any of the unseen things, our views become raised above the things on earth. — Homily on Acts 52 John Chrysostom : "For the things that are seen are temporal." Therefore the afflictions are so too. "But the things that are not seen are eternal." Therefore the crowns are so also. And he said not the afflictions are so, but "the things that are seen;" all of them, whether punishment or rest, so that we should be neither puffed up by the one nor overborne by the other. And therefore when speaking of the things to come, he said not the kingdom is eternal; but, "the things which are not seen are eternal," whether they be a kingdom, or again punishment; so as both to alarm by the one and to encourage by the other. Since then "the things that are seen are temporal, but the things that are not seen are eternal," let us look to them. For what excuse even can we have, if we choose the temporal instead of the eternal? For even if the present be pleasurable, yet it is not abiding; whilst the woe it entails is abiding and irremissible. — Homily 9 on 2 Corinthians Philoxenus of Mabbug : Do thou then, O disciple, make use of faith in its fair order, and turn it not into error; and believe by it in God and in His promises, and believe not in the world and in its delights therewith. Everything which is seen is temporal, and everything which is unseen is eternal, even as Paul also taught; believe then in God, and hope that everlasting blessing will be given to thee by Him, and let faith be the beginning of the way of thy instruction. If thou believest not in these things which are invisible thou canst not forsake the things which are visible; and if thou believest not that the promise of Christ is sure and also in the blessings which were promised by Him to all those who should go forth after His Gospel, thou wilt not forsake that of which thou hast possession, and wilt not run after the good things which He promised to thee. — 13 Ascetic Discourses, Discourse 3 -- On Faith Philoxenus of Mabbug : And Paul revealed unto us the greatness of this exchange in one little word, and shewed us how inferior are the things which we have, and how great are those of God in one short verse, saying, "The things which are seen are temporal, but the things which are unseen are eternal." Who then would not exchange the things of time for those of eternity, except ourselves, and fools like unto us? — 13 Ascetic Discourses, Discourse 9 -- Second Discourse on Poverty
