36. Again, they are concerned with our original constitution, and final restoration, the types of the truth, the covenants, the first and second coming of Christ, His incarnation, sufferings and dissolution, [2625] with the resurrection, the last day, the judgment and recompense, whether sad or glorious; I, to crown all, with what we are to think of the original [2626] and blessed Trinity. Now this involves a very great risk to those who are charged with the illumination [2627] of others, if they are to avoid contracting [2628] their doctrine to a single Person, from fear of polytheism, and so leave us empty terms, if we suppose the Father and the Son and the Holy Spirit to be one and the same Person only: or, on the other hand, severing It into three, either foreign and diverse, or disordered and unprincipled, and, so to say, opposed divinities, thus falling from the opposite side into an equally dangerous error: like some distorted plant if bent far back in the opposite direction.
37. For, amid the three infirmities in regard to theology, atheism, Judaism, and polytheism, one of which is patronised by Sabellius the Libyan, another by Arius of Alexandria, and the third by some of the ultra-orthodox among us, what is my position, can I avoid whatever in these three is noxious, and remain within the limits of piety; neither being led astray by the new analysis and synthesis into the atheism [2629] of Sabellius, to assert not so much that all are one as that each is nothing, for things which are transferred and pass into each other cease to be that which each one of them is, of that we have an unnaturally compound deity, like those mythical creatures, the subject of a picturesque imagination: nor again, by alleging a plurality of severed natures, according to the well named madness [2630] of Arius, becoming involved in a Jewish poverty, and introducing envy into the divine nature, by limiting the Godhead to the Unbegotten One alone, as if afraid that our God would perish, if He were the Father of a real God of equal nature: nor again, by arraying three principles in opposition to, or in alliance with, each other, introducing the Gentile plurality of principles from which we have escaped?
38. It is necessary neither to be so devoted to the Father, as to rob Him of His Fatherhood, for whose Father would He be, if the Son were separated and estranged from Him, by being ranked with the creation, (for an alien being, or one which is combined and confounded with his father, and, for the sense is the same, throws him into confusion, is not a son); nor to be so devoted to Christ, as to neglect to preserve both His Sonship, (for whose son would He be, if His origin were not referred to the Father?) and the rank of the Father as origin, inasmuch as He is the Father and Generator; for He would be the origin of petty and unworthy beings, or rather the term would be used in a petty and unworthy sense, if He were not the origin of Godhead and goodness, which are contemplated in the Son and the Spirit: the former being the Son and the Word, the latter the proceeding and indissoluble Spirit. For both the Unity of the Godhead must be preserved, and the Trinity of Persons confessed, each with His own property.
39. A suitable and worthy comprehension and exposition of this subject demands a discussion of greater length than the present occasion, or even our life, as I suppose, allows, and, what is more, both now and at all times, the aid of the Spirit, by Whom alone we are able to perceive, to expound, or to embrace, the truth in regard to God. For the pure alone can grasp Him Who is pure and of the same disposition as himself; and I have now briefly dwelt upon the subject, to show how difficult it is to discuss such important questions, especially before a large audience, composed of every age and condition, and needing like an instrument of many strings, to be played upon in various ways; or to find any form of words able to edify them all, and illuminate them with the light of knowledge. For it is not only that there are three sources from which danger springs, understanding, speech, and hearing, so that failure in one, if not in all, is infallibly certain; for either the mind is not illuminated, or the language is feeble, or the hearing, not having been cleansed, fails to comprehend, and accordingly, in one or all respects, the truth must be maimed: but further, what makes the instruction of those who profess to teach any other subject so easy and acceptable--viz. the piety [2631] of the audience--on this subject involves difficulty and danger.
40. For having undertaken to contend on behalf of God, the Supreme Being, and of salvation, and of the primary hope [2632] of us all, the more fervent they are in the faith, the more hostile are they to what is said, supposing that a submissive spirit indicates, not piety, but treason to the truth, and therefore they would sacrifice anything rather than their private convictions, and the accustomed doctrines in which they have been educated. I am now referring to those who are moderate and not utterly depraved in disposition, who, if they have erred in regard to the truth, have erred from piety, who have zeal, though not according to knowledge, [2633] who will possibly be of the number of those not excessively condemned, and not beaten with many stripes, [2634] because it is not through vice or depravity that they have failed to do the will of their Lord; and these perchance would be persuaded and forsake the pious opinion which is the cause of their hostility, if some reason either from their own minds, or from others, were to take hold of them, and at a critical moment, like iron from flint, strike fire from a mind which is pregnant and worthy of the light, for thus a little spark would quickly kindle the torch of truth within it.
41. But what is to be said of those who, from vain glory or arrogance, speak unrighteousness against the most High, [2635] arming themselves with the insolence of Jannes and Jambres, [2636] not against Moses, but against the truth, and rising in opposition to sound doctrine? Or of the third class, who through ignorance and, its consequence, temerity, rush headlong against every form of doctrine in swinish fashion, and trample under foot the fair pearls [2637] of the truth?
42. What again of those who come with no private idea, or form of words, better or worse, in regard to God, but listen to all kinds of doctrines and teachers, with the intention of selecting from all what is best and safest, in reliance upon no better judges of the truth than themselves? They are, in consequence, borne and turned about hither and thither by one plausible idea after another, and, after being deluged and trodden down by all kinds of doctrine, [2638] and having rung the changes on a long succession of teachers and formulæ, which they throw to the winds as readily as dust, their ears and minds at last are wearied out, and, O what folly! they become equally disgusted with all forms of doctrine, and assume the wretched character of deriding and despising our faith as unstable and unsound; passing in their ignorance from the teachers to the doctrine: as if anyone whose eyes were diseased, or whose ears had been injured, were to complain of the sun for being dim and not shining, or of sounds for being inharmonious and feeble.
43. Accordingly, to impress the truth upon a soul when it is still fresh, like wax not yet subjected to the seal, is an easier task than inscribing pious doctrine on the top of inscriptions--I mean wrong doctrines and dogmas [2639] --with the result that the former are confused and thrown into disorder by the latter. It is better indeed to tread a road which is smooth and well trodden than one which is untrodden and rough, or to plough land which has often been cleft and broken up by the plough: but a soul to be written upon should be free from the inscription of harmful doctrines, or the deeply cut marks of vice: otherwise the pious inscriber would have a twofold task, the erasure of the former impressions and the substitution of others which are more excellent, and more worthy to abide. So numerous are they whose wickedness is shown, not only by yielding to their passions, but even by their utterances, and so numerous the forms and characters of wickedness, and so considerable the task of one who has been intrusted with this office of educating and taking charge of souls. Indeed I have omitted the majority of the details, lest my speech should be unnecessarily burdensome.
44. If anyone were to undertake to tame and train an animal of many forms and shapes, compounded of many animals of various sizes and degrees of tameness and wildness, his principal task, involving a considerable struggle, would be the government of so extraordinary and heterogeneous a nature, since each of the animals of which it is compounded would, according to its nature or habit, be differently affected with joy, pleasure or dislike, by the same words, or food, or stroking with the hand, or whistling, or other modes of treatment. And what must the master of such an animal do, but show himself manifold and various in his knowledge, and apply to each a treatment suitable for it, so as successfully to lead and preserve the beast? And since the common body of the church is composed of many different characters and minds, like a single animal compounded of discordant parts, it is absolutely necessary that its ruler should be at once simple in his uprightness in all respects, and as far as possible manifold and varied in his treatment of individuals, and in dealing with all in an appropriate and suitable manner.
45. For some need to be fed with the milk [2640] of the most simple and elementary doctrines, viz., those who are in habit babes and, so to say, new-made, and unable to bear the manly food of the word: nay, if it were presented to them beyond their strength, they would probably be overwhelmed and oppressed, owing to the inability of their mind, as is the case with our material bodies, [2641] to digest and appropriate what is offered to it, and so would lose even their original power. Others require the wisdom which is spoken among the perfect, [2642] and the higher and more solid food, since their senses have been sufficiently exercised to discern [2643] truth and falsehood, and if they were made to drink milk, and fed on the vegetable diet of invalids, [2644] they would be annoyed. And with good reason, for they would not be strengthened [2645] according to Christ, nor make that laudable increase, which the Word produces in one who is rightly fed, by making him a perfect man, and bringing him to the measure of spiritual stature. [2646]
46. And who is sufficient for these things? For we are not as the many, able to corrupt [2647] the word of truth, and mix the wine, [2648] which maketh glad the heart of man, [2649] with water, mix, that is, our doctrine with what is common and cheap, and debased, and stale, and tasteless, in order to turn the adulteration to our profit, and accommodate ourselves to those who meet us, and curry favor with everyone, becoming ventriloquists [2650] and chatterers, who serve their own pleasures by words uttered from the earth, and sinking into the earth, and, to gain the special good will of the multitude, injuring in the highest degree, nay, ruining ourselves, and shedding the innocent blood of simpler souls, which will be required at our hands. [2651]
47. Besides, we are aware that it is better to offer our own reins to others more skilful than ourselves, than, while inexperienced, to guide the course of others, and rather to give a kindly hearing than stir an untrained tongue; and after a discussion of these points with advisers who are, I fancy, of no mean worth, and, at any rate, wish us well, we preferred to learn those canons of speech and action which we did not know, rather than undertake to teach them in our ignorance. For it is delightful to have the reasoning [2652] of the aged come to one even until the depth of old age, able, as it is, to aid a soul new to piety. Accordingly, to undertake the training of others before being sufficiently trained oneself, and to learn, as men say, the potter's art on a wine-jar, that is, to practise ourselves in piety at the expense of others' souls seems to me to be excessive folly or excessive rashness--folly, if we are not even aware of our own ignorance; rashness, if in spite of this knowledge we venture on the task.
