62.  But when the student of the Holy Scriptures, prepared in the way I have indicated, shall enter upon his investigations, let him constantly meditate upon that saying of the apostle’s, “Knowledge puffeth up, but charity edifieth.”118    1 Cor. viii. 1.  For so he will feel that, whatever may be the riches he brings with him out of Egypt, yet unless he has kept the passover, he cannot be safe.  Now Christ is our passover sacrificed for us,119    1 Cor. v. 7. and there is nothing the sacrifice of Christ more clearly teaches us than the call which He himself addresses to those whom He sees toiling in Egypt under Pharaoh:  “Come unto me, all ye that labor and are heavy laden, and I will give you rest.  Take my yoke upon you, and learn of me; for I am meek and lowly in heart:  and ye shall find rest unto your souls.  For my yoke is easy, and my burden is light.”120    Matt. xi. 28–30.  To whom is it light but to the meek and lowly in heart, whom knowledge doth not puff up, but charity edifieth?  Let them remember, then, that those who celebrated the passover at that time in type and shadow, when they were ordered to mark their door-posts with the blood of the lamb, used hyssop to mark them with.121    Ex. xii. 22.  Now this is a meek and lowly herb, and yet nothing is stronger and more penetrating than its roots; that being rooted and grounded in love, we may be able to comprehend with all saints what is the breadth, and length, and depth, and height,122    Eph. iii. 17, 18.—that is, to comprehend the cross of our Lord, the breadth of which is indicated by the transverse wood on which the hands are stretched, its length by the part from the ground up to the cross-bar on which the whole body from the head downwards is fixed, its height by the part from the crossbar to the top on which the head lies, and its depth by the part which is hidden, being fixed in the earth.  And by this sign of the cross all Christian action is symbolized, viz., to do good works in Christ, to cling with constancy to Him, to hope for heaven, and not to desecrate the sacraments.  And purified by this Christian action, we shall be able to know even “the love of Christ which passeth knowledge,” who is equal to the Father, by whom all things, were made, “that we may be filled with all the fullness of God.”123    Eph. iii. 19.  There is besides in hyssop a purgative virtue, that the breast may not be swollen with that knowledge which puffeth up, nor boast vainly of the riches brought out from Egypt.  “Purge me with hyssop,” the psalmist says,124    Ps. li. 7, 8. “and I shall be clean; wash me, and I shall be whiter than snow.  Make me to hear joy and gladness.”  Then he immediately adds, to show that it is purifying from pride that is indicated by hyssop, “that the bones which Thou hast broken125    Ossa humiliata, Vulgate. may rejoice.”

62. Sed hoc modo instructus divinarum Scripturarum studiosus, cum ad eas perscrutandas accedere coeperit, illud apostolicum cogitare non cesset: Scientia inflat, charitas aedificat (I Cor. VIII, 1). Ita enim sentiet, quamvis de Aegypto dives exeat, tamen nisi Pascha egerit, salvum se esse non posse. Pascha autem nostrum immolatus est Christus (Id. V, 7), nihilque magis immolatio Christi nos docet, quam illud quod ipse clamat, tanquam ad eos quos in Aegypto sub Pharaone videt laborare: Venite ad me, qui laboratis et onerati estis, et ego reficiam vos. Tollite jugum meum super vos, et discite a me quia mitis sum et humilis corde; et invenietis requiem animabus vestris. Jugum enim meum lene est, et sarcina mea levis est (Matth. XI, 28-30): quibus, nisi mitibus et humilibus corde, quos non inflat scientia, sed charitas aedificat? Meminerint ergo eorum qui Pascha illo tempore per umbrarum imaginaria celebrabant , cum signari postes sanguine agni juberentur, hyssopo fuisse signatos (Exod. XII, 22). Herba haec mitis et humilis est, et nihil fortius et penetrabilius ejus radicibus: ut in charitate radicati et fundati possimus comprehendere cum omnibus sanctis, quae sit latitudo, et longitudo, et altitudo, et profundum, id est, crucem Domini: cujus latitudo dicitur in transverso ligno, quo extenduntur manus; longitudo, a terra usque ad ipsam latitudinem, quo a manibus et infra totum corpus affigitur; altitudo, a latitudine sursum usque ad summum, cui adhaeret caput ; profundum vero, quod terrae infixum absconditur. Quo signo crucis, omnis actio christiana describitur, bene operari in Christo, et ei perseveranter inhaerere, sperare coelestia, sacramenta non profanare . Per hanc actionem purgati valebimus cognoscere etiam supereminentem scientiae charitatem Christi , qua aequalis est Patri, per quem facta sunt omnia, ut impleamur in omnem plenitudinem Dei (Ephes. III, 17-19). Est etiam in hyssopo vis purgatoria, ne inflante scientia de divitiis ab Aegypto ablatis, superbe aliquid pulmo tumidis anhelet: Asperges me, inquit, hyssopo et mundabor; lavabis me, et super nivem dealbabor. Auditui meo dabis exsultationem et laetitiam. Deinde consequenter annectit ut ostendat purgationem a superbia significari hyssopo, Et exsultabunt ossa humiliata (Psal. L, 9, 10).
