5 [If the fault be a point of faith, let the document be pointed out to me. Again, let a fair and impartial inquiry be appointed. Let the accusation be read; let it be brought to the test, whether it does not arise from ignorance in the accuser, not from blame in the matter of the writing. For right things often do not seem such to those who are deficient in accurate judgment. Equal weights seem unequal when the arms of the balance are of different sizes.] Men whose sense of taste is destroyed by sickness, sometimes think honey sour. A diseased eye does not see many things which do exist, and notes many things which do not exist. The same thing frequently takes place with regard to the force of words, when the critic is inferior to the writer. The critic ought really to set out with much the same training and equipment as the author. A man ignorant of agriculture is quite incapable of criticising husbandry, and the distinctions between harmony and discord can only be adequately judged by a trained musician. But any one who chooses will set up for a literary critic, though he cannot tell us where he went to school, or how much time was spent in his education, and knows nothing about letters at all. I see clearly that, even in the case of the words of the Holy Spirit, the investigation of the terms is to be attempted not by every one, but by him who has the spirit of discernment, as the Apostle has taught us, in the differences of gifts;— “For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit; to another faith by the same Spirit; to another the gift of healing by the same Spirit; to another the working of miracles; to another prophecy; to another discerning of spirits.” If, therefore, my gifts are spiritual, he who wishes to judge them must show proof of his own possession of the gift of “discerning of spirits.” If, on the contrary, as he calumniously contends, my gifts are of the wisdom of this world, let him show that he is an adept in this world's wisdom, and I will submit myself to his verdict. And [let no one suppose that I am making excuses to evade the charge. I put it into your hands, dearest brethren, to investigate for yourselves the points alleged against me. Are you so slow of intelligence as to be wholly dependent upon advocates for the discovery of the truth? If the points in question seem to you to be quite plain of themselves, persuade the jesters to drop the dispute. [If there be anything you do not understand, put questions to me, through appointed persons who will do justice to me; or ask of me explanations in writing. And take all kinds of pains that nothing may be left unsifted.
6. What clearer evidence can there be of my faith, than that I was brought up by my grandmother, blessed woman, who came from you? I mean the celebrated Macrina who taught me the words of the blessed Gregory; which, as far as memory had preserved down to her day, she cherished herself, while she fashioned and formed me, while yet a child, upon the doctrines of piety. And when I gained the capacity of thought, my reason being matured by full age, I travelled over much sea and land, and whomsoever I found walking in the rule of godliness delivered, those I set down as fathers,] and made them my soul's guides in my journey to God. And up to this day, by the grace of Him who has called me in His holy calling to the knowledge of Himself, I know of no doctrine opposed to the sound teaching having sunk into my heart; nor was my soul ever polluted by the ill-famed blasphemy of Arius. If I have ever received into communion any who have come from that teacher, hiding their unsoundness deep within them, or speaking words of piety, or, at any rate, not opposing what has been said by me, it is on these terms that I have admitted them; and I have not allowed my judgment concerning them to rest wholly with myself, but have followed the decisions given about them by our Fathers. For after receiving the letter of the very blessed Father Athanasius, bishop of Alexandria, which I hold in my hand, and show to any one who asks, wherein he has distinctly declared that any one expressing a wish to come over from the heresy of the Arians and accepting the Nicene Creed, is to be received without hesitation and difficulty, citing in support of his opinion the unanimous assent of the bishops of Macedonia and of Asia; I, considering myself bound to follow the high authority of such a man and of those who made the rule, and with every desire on my own part to win the reward promised to peacemakers, did enroll in the lists of communicants all who accepted that creed.
7. [The fair thing would be to judge of me, not from one or two who do not walk uprightly in the truth, but from the multitude of bishops throughout the world, connected with me by the grace of the Lord. Make enquiries of Pisidians, Lycaonians, Isaurians, Phrygians of both provinces, Armenians your neighbours, Macedonians, Achæans, Illyrians, Gauls, Spaniards, the whole of Italy, Sicilians, Africans, the healthy part of Egypt, whatever is left of Syria; all of whom send letters to me, and in turn receive them from me.] From these letters, alike from all which are dispatched from them. and from all which go out from us to them, you may learn that we are all of one mind, and of one opinion. [Whoso shuns communion with me, it cannot escape your accuracy, cuts himself off from the whole Church. Look round about, brethren, with whom do you hold communion? If you will not receive it from me, who remains to acknowledge you? Do not reduce me to the necessity of counselling anything unpleasant concerning a Church so dear to me.] There are things now which I hide in the bottom of my heart, in secret groaning over and bewailing the evil days in which we live, in that the greatest Churches which have long been united to one another in brotherly love, now, without any reason, are in mutual opposition. Do not, oh! Do not, drive me to complain of these things to all who are in communion with me. Do not force me to give utterance to words which hitherto I have kept in check by reflection and have hidden in my heart. Better were it for me to be removed and the Churches to be at one, than that God's people should suffer such evil through our childish ill-will. [Ask your fathers, and they will tell you that though our districts were divided in position, yet in mind they were one, and were governed by one sentiment. Intercourse of the people was frequent; frequent the visits of the clergy; the pastors, too, had such mutual affection, that each used the other as teacher and guide in things pertaining to the Lord.]
