quia non qui caeperit, sed qui perseveraverit, salvus erit; et vos quantum potestis, jugi oratione, et cordis compunctione ignem in vobis divini amoris accendite; ne forte flamma charitatis, quae in vobis fervere fideliter coepit, per aliquam negligentiam refrigescat.
because not the one who has begun, but the one who has persevered, will be saved; and you, as far as you can, by unceasing prayer and by compunction of heart kindle in yourselves the fire of divine love, lest perhaps the flame of charity, which has faithfully begun to glow in you, should grow cold through some negligence.
2. Linguae concinant mores; vocibus consonent affectus pii. Et hoc ante omnia non solum orationibus, sed etiam sanctis cogitationibus studete, ut quod verbis psallitis, orationibus impleatis, et Spiritus sanctus, qui vobis sonat in ore, ipse etiam habitare dignetur in corde. Bonum quidem est et satis acceptabile Deo, quando lingua fideliter psallit; sed tunc est vere bonum, quando linguae concordat etiam vita. Consentiant simul voces et mores; ne forte bonae voces contra malos mores testimonium ferant, et ipsa vos lingua vestra redarguat. Si enim aliud sonat in ore, et aliud apparet in opere; quod lingua videtur aedificare, incipit conversatio mala destruere. Vos vero, fratres, non solum suavitas vocis, sed etiam sensus ipsius lectionis teneat occupatos; ut quomodo sonus vocis delectat in auribus, sic virtus ipsius lectionis dulcescat in cordibus, secundum illud quod scriptum est, Quam dulcia faucibus meis eloquia tua, Domine (Psal. CXVIII, 103)! et iterum, Eloquia Domini desiderabilia super aurum, et lapidem pretiosum multum, et dulciora super mel et favum (Psal. XVIII, 11). Qui enim quando psallit, suavitatem tantummodo vocis et compositionem cujusque soni attendit, et quid in ipsis intelligi debeat non attendit, aures ejus accipiunt transitorium cibum, sed ad animam ejus non pervenit Dei verbum; ac si velut ceram quodam modo quis ruminat, et de mellis dulcedine omnino non gustat.
2. Let conduct sing in harmony with tongues; let devout feelings sound in accord with voices. And above all apply yourselves to this, not only with prayers but also with holy thoughts, that what you sing with words you may fulfil with prayers, and that the Holy Spirit, Who sounds in your mouth, may Himself also deign to dwell in your heart. It is indeed good and quite acceptable to God when the tongue sings psalms faithfully; but it is truly good only when life too agrees with the tongue. Let voices and conduct be in accord together, lest perhaps good voices bear witness against bad conduct, and your own tongue convict you. For if one thing sounds in the mouth and another appears in the deed, what the tongue seems to build up, a bad manner of life begins to destroy. But you, brothers, let not only the sweetness of the voice but also the sense of the reading itself keep occupied, so that, just as the sound of the voice delights in the ears, so the power of the reading itself may grow sweet in the hearts, according to that which is written: How sweet to my palate are Thy words, O Lord (Ps. 118:103)! and again: The words of the Lord are more desirable than gold and very precious stone, and sweeter than honey and the honeycomb (Ps. 18:11). For whoever, when he sings psalms, attends only to the sweetness of the voice and the arrangement of each sound, and does not attend to what ought to be understood in them, his ears receive a passing food, but the word of God does not reach his soul; it is as if someone were in a manner chewing the wax and not tasting the sweetness of the honey at all.
3. Qualiter inter psallendum concipiantur. Vos vero, fratres, sicut jam supra suggessi, ante omnia virtutes Psalmorum intus attendite. Quando quisque vestrum psallit, versiculum Psalmi, ubi ait, Confundantur superbi, quia injuste iniquitatem fecerunt in me (Psal. CXVIII, 78); conetur superbiam fugere, ut aeternam confusionem mereatur evadere. Quando psallimus, Perdes omnes qui fornicantur abs te (Psal. LXXII, 27); omnes malas concupiscentias studeamus evadere. Quando psallimus quod beatus est vir, qui in lege Domini meditabitur die ac nocte (Psal. I, 2); superfluas occupationes et mordaces jocos, otiosos luxuriososque sermones, quasi venenum diaboli respuamus; et lectionem divinam aut ipsi frequentius relegamus; aut si nos ipsi legere non possumus, illos qui legunt libenter et frequenter audire studeamus. Quoties psallimus, Si reddidi retribuentibus mihi mala, decidum merito ab inimicis meis inanis: persequatur inimicus animam meam, et comprehendat et conculc⟨e⟩t in terra vitam meam, et gloriam meam in pulverem reducat (Psal. VII, 5, 6): quando ista et alia dicimus, ne ipsi contra nos tam duram maledictionem proferre videamur, nulli unquam hominum malum pro malo reddamus; ut cum secura conscientia possimus dicere, Dimitte nobis debita nostra, sicut et nos dimittimus debitoribus nostris (Matth. VI, 12). Et quia longum est omnia replicare, quae de istis tribus aut quatuor peccatis, id est, superbia, fornicatione vel odio diximus, hoc de reliquis omnibus vitiis sentiamus. Et quotiescumque in Psalmis peccatores maledicuntur, studeamus peccatum fugere; ne ipsi nos videamur ore proprio maledicere. Quoties in Psalmis justi, misericordes, sobrii, casti vel humiles collaudantur, tales esse cum Dei adjutorio laboremus; ut benedictio quae ad illos dirigitur, etiam ad nos divino munere proferatur. Iterum atque iterum rogo atque supplico, ut quotiescumque psallitis, quid in ipsis Psalmis intrinsecus intelligi vel observari debeat, attentius cogitetis; ut dum lingua vestra Dominum laudat, ad animam vestram benedictio divina perveniat: praestante Domino nostro Jesu Christo, qui vivit et regnat in saecula saeculorum. Amen.
3. How [the Psalms] are to be taken in while singing. But you, brothers, as I have already suggested above, attend above all inwardly to the powers of the Psalms. When any one of you sings the verse of the Psalm where it says, Let the proud be confounded, because they have unjustly done iniquity against me (Ps. 118:78), let him strive to flee pride, so that he may deserve to escape eternal confusion. When we sing, Thou wilt destroy all who commit fornication away from Thee (Ps. 72:27), let us be eager to escape all evil desires. When we sing that blessed is the man who will meditate on the law of the Lord day and night (Ps. 1:2), let us spit out superfluous occupations and biting jests, idle and wanton talk, as the poison of the devil; and let us either read the divine reading over again more frequently ourselves, or, if we ourselves cannot read, let us be eager to listen willingly and frequently to those who read. Whenever we sing, If I have repaid evil to those who repaid me, may I deservedly fall empty before my enemies: let the enemy pursue my soul, and seize it, and trample my life into the ground, and bring my glory down to dust (Ps. 7:5–6): when we say these and other things, lest we ourselves seem to utter so harsh a curse against ourselves, let us never repay any man evil for evil, so that with a secure conscience we may be able to say, Forgive us our debts, as we also forgive our debtors (Matt. 6:12). And since it is long to go over everything, what we have said about these three or four sins, that is, pride, fornication or hatred, let us think the same of all the remaining vices. And whenever sinners are cursed in the Psalms, let us be eager to flee sin, lest we ourselves seem to curse with our own mouth. Whenever the just, the merciful, the sober, the chaste or the humble are praised in the Psalms, let us labour with God's help to be such, so that the blessing which is directed to them may by divine gift be extended to us also. Again and again I ask and beseech that, whenever you sing psalms, you consider more attentively what ought to be understood or observed inwardly in the Psalms themselves, so that while your tongue praises the Lord, the divine blessing may reach your soul: by the grace of our Lord Jesus Christ, Who lives and reigns for ever and ever. Amen.
