6.22. Yes, let no one be lost, but let us all abide in one spirit, with one mind striving side by side for the faith of the gospel, being in full accord and of one mind armed with the shield of faith, loins girded about with truth, acknowledging one war alone, that against he Devil and his minions, fearing not those who can kill the body but cannot take the soul, but fearing the Lord of both soul and body: guarding the truth that we have received from our fathers, reverencing the Father and Son and Holy Spirit, in which names we have been baptized, in which we believe, and under which we have been enlisted, dividing them before combining them, and not regarding the three as a single individual (for they are not without individual reality nor do the compromise a single reality, as though our treasure lay in names and not in actual fact), but rather believing the three to be a single entity. For they are a single entity not in individual reality but in divinity, a unity worshipped in Trinity and a Trinity summed up in unity, venerable as one whole, as one whole royal, sharing the same throne, sharing the same glory, above space, above time, uncreated, invisible, impalpable, uncircumscribed, its internal ordering known only to itself, but for us equally the object of reverence and adoration,, and alone taking possession of the Holiest of Holies and excluding all of creation, part by the first veil, and part by the second. The first veil separates the heavenly and angelic realm from the Godhead, and the second, our world from that of the heavens. These things, my brothers, let us do, and such let our devotion be; and as for those who disagree, let us regard them as a plague against the truth and make every effort to help them and heal them; but if they are not receptive to cure let us turn away from them less they infect us with their affliction before we give them of our own health. And the God of peace, which passes all understanding, will be with us in Jesus Christ our Lord. Amen.
32.21 If you have the word of understanding, answer, says Scripture, and no one will hold you back; if not, put a curb on your lips. How much more this applies to those prepared to impart instruction! In proper time, teach; if not, hold your tongue and open your ears. Seek to meditate on things divine, but stay within the proper bounds; to speak out the things of the Spirit and, if possible, nothing else; and to speak out with every breath you take, if not more, but in the consciousness of what has been assigned to you, for it is an inspiring and ennobling things to have the thought of matters divine act as a goad ever urging you to God. Try not to trouble yourself over the precise nature of Father, the existence of his only-begotten Son, the glory and power of the Spirit, the single divinity and splendour in the Three, the indivisible nature as well as confession, glory, and hope of those who truly believe. Try to keep to the words that you have known from your childhood; leave sophisticated language to the more advanced. It is enough for you to have the foundation; leave it to the craftsmen to build on it. It is enough to strengthen your heart with simple bread; leave the rich dishes to the rich. No reasonable person can condemn you for not providing a lavish feast, only for failing to offer some bread and a drink of water, whether to a disciple of Christ or anyone else, if you possibly can. Do not be hasty in your words. Wisdom bids you. If thou art poor, measure not thyself with a rich man, nor seek to be wiser than the wise. Self-knowledge also is wisdom, but not a high opinion of oneself; that would be like the affliction that affects the vocal chords: they give out completely when strained to excess. It is better to be wise and yield graciously than to be ignorant and let arrogance lead one out of one’s depth. Be quick to respond only whenever you are asked for your confession; beyond that, hesitate: in the first case, it is slowness to act that carries the risk; in the second, haste.
