3. Sic ergo munita est castri Dominici fortitudo, ut nihil jam timere oporteat, si tamen fideliter et viriliter agere voluerimus; ut videlicet nec proditores, nec pavidi, nec desides inveniamur. Nam proditores quidem fiunt, quicunque in hoc Domini castrum inimicos ejus introducere moliuntur, quales sunt utique detractores, Deo odibiles, qui discordias seminant, et nutriunt scandala inter fratres. Sicut enim in pace factus est locus Domini; sic in discordia locum diabolo fieri manifestum est. Non miremini, fratres, si durius loqui videor; quia veritas neminem palpat. Omnino proditorem sese noverit, si quis forte, quod absit! vitia quaelibet in hanc domum conatur inducere, et templum Dei speluncam facere daemoniorum. Gratias Deo, non multos hic invenimus hujusmodi. Sed tamen deprehendimus interdum forte nonnullos, qui colloquantur hostibus, et paciscantur foedus cum morte, hoc est, moliantur, quod in eis est, imminuere ordinis disciplinam, intepescere fervorem, turbare pacem, laedere charitatem. Verum nos quidem caveamus ab eis, quantum possumus; sicut scriptum est de quibusdam: Jesus autem non credebat se eis (Joan. II, 24). Dico autem vobis quia, licet portentur modo, sed portabunt cito grave judicium, nisi se citius emendaverint, sicut grave damnum moliuntur inferre. Quid enim, frater? vanitati, aut tepiditati, seu cuilibet alteri vitio fidem servas operibus, et Deo per tonsuram mentiris? Optimum certe castrum tulisti Christo, si inimicis ejus tradideris Claram-Vallem. Optimos inde singulis annis, et pretiosos in oculis suis reditus accipit: et praedam multam, quam hostibus eripit, in hunc munitionis suae locum solet inducere, et habet fiduciam multam in fortitudine ejus. Ecce enim quos redemit de manu inimici, et de regionibus congregavit eos, a solis ortu et occasu, ab aquilone et mari. Quibus ergo proditorem castri hujus, postquam deprehensus et comprehensus fuerit (neque enim latere aut fugere potest), quibus, inquam, putas exponendum esse suppliciis? Non utique communi caeterorum morte damnabitur, sed exquisitis illum necesse est interire tormentis. Sed non modo plus immoror circa ista: credo melius deinceps ab hac tam exsecrabili proditione cavebimus, studentes de caetero majori sollicitudine non attrahere, sed repellere vitia, quaecunque illa sint, seu carnalia, seu etiam saecularia, ne proditorum notam vel poenam incurrere mereamur.
3. So the strength of the Lord's fortress is fortified in such a way that there is no need now to fear anything, provided we are willing to act faithfully and manfully: that is, that we be found neither traitors, nor cowards, nor idlers. For they become traitors, all who strive to bring His enemies into this fortress of the Lord; such indeed are detractors, hateful to God, who sow discord and nourish scandals among the brethren. For as the Lord's place was made in peace, so it is plain that in discord a place is made for the devil. Do not wonder, brethren, if I seem to speak rather harshly; for truth flatters no one. Let anyone know himself to be altogether a traitor if perhaps, which God forbid, he tries to bring any vices into this house and make the temple of God a den of demons. Thanks be to God, we do not find many such here. Yet we do sometimes catch a few, perhaps, who parley with the enemy and strike a covenant with death, that is, who strive, so far as in them lies, to lessen the discipline of the order, to let fervour cool, to disturb peace, to wound charity. Let us at any rate beware of them as far as we can; as it is written of certain men: But Jesus did not trust Himself to them (John 2:24). And I tell you that, although they are borne with now, they will soon bear a heavy judgement unless they amend themselves quickly, as heavy as the harm they strive to inflict. For what, brother? Do you keep faith in your works with vanity, or lukewarmness, or any other vice, and lie to God by your tonsure? A fine fortress indeed you have taken from Christ, if you hand Clairvaux over to His enemies. From it He receives every year the finest revenues, precious in His eyes; and the great spoil He snatches from the enemy He is wont to bring into this place of His fortification, and He has great confidence in its strength. For see, those whom He redeemed from the hand of the enemy He gathered out of the lands, from the rising and the setting of the sun, from the north and from the sea. To what punishments, then, do you think the traitor of this fortress must be given over, once he has been caught and seized (for he can neither hide nor flee): to what punishments, I say? He will surely not be condemned to the common death of the rest; he must perish by exquisite torments. But I will not dwell on these things any longer now: I believe we shall henceforth be better on our guard against so execrable a treachery, striving from now on with greater care not to draw vices in but to drive them out, whatever they may be, whether carnal or worldly, lest we deserve to incur the brand or the punishment of traitors.
4, Secundo loco etiam illud cavendum, ne quis forte, pusillanimitate dejectus, fugiat a munitione, ibi trepidans timore ubi non est timor; ubi vero summum periculum est, insana temeritate securus. Hostilibus enim manibus, hostilibus gladiis se exponit quicunque est ille qui fugit, ac si ignoret quoniam hostes illi omnino carent misericordia, crudeles quidem in alienos, sed multo crudeliores in suos, quippe crudelissimi in se ipsos.
4. In the second place we must also beware lest anyone, cast down perhaps by faint-heartedness, flee from the fortification, trembling with fear where there is no fear, but, where the danger is greatest, secure in mad rashness. For whoever flees exposes himself to hostile hands and hostile swords, as if he did not know that those enemies are utterly without mercy: cruel indeed to strangers, but much crueller to their own, being, of course, cruellest of all to themselves.
