Chapter I
1 I write this to remind you of the request which I made when I was with you, that you would do me the kindness of visiting our brother, whom we mentioned in conversation, in order to ask him to forgive me, if he has construed as a harsh and unfriendly attack upon himself any statement made by me in a recent letter (which I do not regret having written), affirming that the eyes of this body cannot see God, and never shall see Him. I added immediately the reason wily I made this statement. namely, to prevent men from believing that God Himself is corporeal and visible, as occupying a place determined by size and by distance from us (for the eye of this body can see nothing except under these conditions), and to prevent men from understanding the expression "face to face " as if God were limited within the members of a body. Therefore I do not regret having made this statement, as a protest against our forming such unworthy and profane ideas concerning God as to think that He is not everywhere in His totality, but susceptible of division, and distributed through localities in space; for such are the only objects cognizable through these eyes of ours.
2. But if, while holding no such opinion as this concerning God, but believing Him to be a Spirit, unchangeable, incorporeal, present in His whole Being everywhere, any one thinks that the change on this body of ours (when from being a natural body it shall become a spiritual body) will be so great that in such a body it will be possible for us to see a spiritual substance not susceptible of division according to local distance or dimension, or even confined within the limits of bodily members, but everywhere present in its totality, I wish him to instruct me in this matter, if what he has discovered is true; but if in this opinion he is mistaken, it is far less objectionable to ascribe to the body something that does not belong to it, than to take away from God that which belongs to Him. And even if that opinion be correct, it will not contradict my words in that letter; for I said that the eyes of this body shall not see God, meaning that the eyes of this body of ours can see nothing but bodies which are separated from them by some interval of space, for if there be no interval, even bodies themselves cannot through the eyes be seen by us.
3. Moreover, if our bodies shall be changed into something so different from what they now are as to have eyes by means of which a substance shall be seen which is not diffused through space or confined within limits, having one part in one place, another in another, a smaller in a less space, a greater in a larger, but in its totality spiritually present everywhere -- these bodies shall be something very different from what they are at present, and shall no longer be themselves, and shall be not only freed from mortality, and corruption, and weight, but somehow or other shall be changed into the quality of the mind itself, if they shall be able to see in a manner which shall be then granted to the mind, but which is meanwhile' not granted even to the mind itself. For if, when a man's habits are changed, we say he is not the man he was -- if, when our age is changed, we say that the body is not what it was, how much more may we say that the body shall not be the same when it shall have undergone so great a change as not only to have immortal life, but also to have power to see Him who is invisible? Wherefore, if they shall thus see God, it is not with the eyes of this body that He shall be seen, because in this also it shall not be the same body, since it has been changed to so great an extent in capacity and power; and this opinion is, therefore, not contrary to the words of my letter. If, however; the body shall be changed only to this extent, that whereas now it is mortal, then it shall be immortal, and whereas now it weighs down the soul, then, devoid of weight, it shall be most ready for every motion, but unchanged in the faculty of seeing objects which are discerned by their dimensions and distances, it will still be utterly impossible for it to see a substance that is incorporeal and is in its totality present everywhere. Whether, therefore, the former or the latter supposition be correct, in both cases it remains true that the eyes of this body shall not see God; or if they are to see Him, they shall not be the eyes of this body, since after so great a change they shall be the eyes of a body very different from this.
4. But if this brother is able to propound anything better on this subject, I am ready to learn either from himself or from his instructor. If I were saying this ironically, I would also say that I am prepared to learn concerning God that He has a body having members, and is divisible in different localities in space; which I do not say, because I am not speaking ironically, and I am perfectly certain that God is not in any respect of such a nature; and I wrote that letter to prevent men from believing Him to be such. In that letter, being carried away by my zeal to warn against error, and writing more freely because I did not name the person whose views I assailed, I was too vehement and not sufficiently guarded,and did not consider as I ought to have done the respect which was due by one brother and bishop to the office of another: this I do not defend, but blame; this I condemn rather than excuse, and beg that it may be forgiven. I entreat him to remember our old friendship, and forget my recent offense. Let him do that which he is displeased with me for not having done; let him exhibit in granting pardon the gentleness which I have failed to show in writing that letter. I thus ask, through your kindly mediation, what I had resolved to ask of him in person if I had had an opportunity. I indeed made an effort to obtain an interview with him (a venerable man, worthy of being honoured by us all, writing to request it in my name), but he declined to come, suspecting, I suppose, that, as very often happens among men, some plot was prepared against him. Of my absolute innocence of such guile, I beg you to do your utmost to assure him, which by seeing him personally you can more easily do. State to him with what deep and genuine grief I conversed with you about my having hurt his feelings. Let him know how far I am from slighting him, how much in him I fear God, and am mindful of our Head in whose body we are brethren. My reason for thinking it better not to go to the place in which he resides was, that we might not make ourselves a laughing-stock to those without the pale of the Church, thereby bringing grief to our friends and shame to ourselves. All this may be satisfactorily arranged through the good offices of your Holiness and Charity; nay, rather, the satisfactory issue is in the hands of Him who, by the faith which is His gift, dwells in your heart, whom I am confident that our brother does not refuse to honour in you, since he knows Christ experimentally as dwelling in himself.
