If the thing is creditable, why is it left to mountebanks? What, do you make yourself a mountebank, and yet art not ashamed? Why is it ye permit not your gentlewomen to do so? Is it not that you set it down as a mark of an immodest, and not of a discreet character? Great are the evils that dwell in a soul given to jesting; great is the ruin and desolation. Its consistency is broken, the building is decayed, fear is banished, reverence is gone. A tongue you have, not that you may ridicule another man, but that you may give thanks unto God. Look at your merriment-makers, as they are called, those buffoons. These are your jesters. Banish from your souls, I entreat you, this graceless accomplishment. It is the business of parasites, of mountebanks, of dancers, of harlots; far be it from a generous, far be it from a highborn soul, aye, far too even from slaves. If there be any one who has lost respect, if there be any vile person, that man is also a jester. To many indeed the thing appears to be even a virtue, and this truly calls for our sorrow. Just as lust little by little drives headlong into fornication, so also does a turn for jesting. It seems to have a grace about it, yet there is nothing more graceless than this. For hear the Scripture which says, “Before the thunder goes lightning, and before a shamefaced man shall go favor.” Now there is nothing more shameless than the jester; so that his mouth is not full of favor, but of pain. Let us banish this custom from our tables. Yet are there some who teach it even to the poor! O monstrous! They make men in affliction play the jester. Why, where shall not this pest be found next? Already has it been brought into the Church itself. Already has it laid hold of the very Scriptures. Need I say anything to prove the enormity of the evil? I am ashamed indeed, but still nevertheless I will speak; for I am desirous to show to what a length the mischief has advanced, that I may not appear to be trifling, or to be discoursing to you on some trifling subject; that even thus I may be enabled to withdraw you from this delusion. And let no one think that I am fabricating, but I will tell you what I have really heard. A certain person happened to be in company with one of those who pride themselves highly on their knowledge (now I know I shall excite a smile, but still I will say it notwithstanding); and when the platter was set before him, he said, “Take and eat, children, lest your belly be angry!” And again, others say, “Woe unto you, Mammon, and to him that has you not;” and many like enormities has jesting introduced; as when they say, “Now is there no nativity.” And this I say to show the enormity of this base temper; for these are the expressions of a soul destitute of all reverence. And are not these things enough to call down thunderbolts? And one might find many other such things which have been said by these men.
Wherefore, I entreat you, let us banish the custom universally, and speak those things which become us. Let not holy mouths utter the words of dishonorable and base men. “For what fellowship have righteousness and iniquity, or what communion has light with darkness?” Happy will it be for us, if, having kept ourselves aloof from all such foul things, we be thus able to attain to the promised blessings; far indeed from dragging such a train after us, and sullying the purity of our minds by so many. For the man who will play the jester will soon go on to be a railer, and the railer will go on to heap ten thousand other mischiefs on himself. When then we shall have disciplined these two faculties of the soul, anger and desire (vid. Plat. Phædr. cc. 25, 34), and have put them like well-broken horses under the yoke of reason, then let us set over them the mind as charioteer, that we may “gain the prize of our high calling”; which God grant that we may all attain, through Jesus Christ our Lord, with Whom, together with the Holy Ghost, be unto the Father, glory, might, and honor, now, and ever, and throughout all ages. Amen.
