namely, than yea and nay, saith he, is of the devil),518 why dost thou bring this person and that person forward? For not because of the carelessness of thy fellow servants, but from the injunctions of his own laws, will God record his vote against thee. I have commanded, he says, thou oughtest to obey, not to shelter thyself behind such and such a person and concern thyself with other persons’ evil. Since the great David sinned a grievous sin, is it then safe for us to sin? Tell me: on this account then we ought to make sure of this point, and only to emulate the good works of the saints; and if there is carelessness, and transgres- sion of the law anywhere, we ought to flee from it with great care. For our reckoning is not with our fellow-servants, but with our Master, and to him we shall give account for all done in our life. Let us prepare ourselves therefore for this tribunal. For even if he who transgresses this law be beyond everything revered and great, he shall certainly pay the penalty attaching to the transgression. For God is no respecter of persons. How then and in what way is it possible to flee from this sin? For one ought to show not only that the crime is grievous, but to give counsel how we may escape from it. Hast thou a wife, hast thou a servant, children, friends, acquaintance, neighbors? To all these enjoin caution on these matters. Custom is a grievous thing, terrible to supplant, and hard to guard against, and it often attacks us un- willing and unknowing; therefore in so far as thou knowest the power of custom, to such an extent study to be freed from any evil custom, and transfer thyself to any other most useful one. For as that custom is often able to trip thee up, though thou art careful, and guardest thyself, and takest thought, and consideration, so if thou transferrest thyself to the good custom of abstaining from oaths, thou wilt not be able, either involuntarily or carelessly, to fall into the fault of oaths. For custom is really great and has the power of nature. In order then that we do not continually distress ourselves let us transfer ourselves to another custom, and ask thou each one of thy kindred and acquaintance this favor, that he advise thee and exhort thee to flee from oaths, and reprove thee, when detected in them. For the watch over thee which takes place on their part, is to them too counsel and a suggestion to what is right. For he who reproves another for oaths, will not himself easily fall into this pit. For much swearing is no ordinary pit, not only when it is about little matters but about the greatest. And we, whether buying vegetables, or quarrelling over two farthings, or in a rage with our servants and threatening them, always call upon God as our witness. But a freeman, possessed of some barren dignity, thou wouldest not dare to call upon as witness in the market to such things; but even if thou attemptedst it, thou wilt pay the penalty of thine insolence. But the King of Heaven, the Lord of Angels, when disputing both about purchases and money, and what not, thou draggest in for a testimony. And how can these things be borne? whence then should we escape from this evil custom? After setting those guards of which I spoke round us, let us fix on a specified time to ourselves for amendment, and adding thereto 518 Matt. v. 35. 226 First Instruction.
