lumen istud divinitatis aestimari, comprehendi et definiri non posse, ideo praemoneo ut tantum de unitate substantiae spiritualiter credatis, et Filium verum de vero Patre cognoscatis. De qualitate autem rei requirere non debetis: quia Deus credi se voluit, non dijudicari, nec examinari; quia qualis aut quantus sit, sciri non potest. Hoc enim Prophetae, hoc Apostoli praedicaverunt. Denique pro captu, pro viribus, pro fide nostra intueamur, Deus quid sit: et videamus an ei possit aliquid comparari. Certe hoc est Deus, quod et cum dicitur non potest dici, cum aestimatur non potest aestimari, cum comparatur non potest comparari, cum definitur ipsa definitione crescit: qui coelum manu sua cooperit, pugno omnem mundi ambitum claudit; quem totum omnia nesciunt, et metuendo sciunt; cujus nomini et virtuti famulatur hic orbis, et ipsa sibi elementorum succedentium momentanea vicissitudo serviendum testatur.
that this light of the divinity cannot be assessed, comprehended and defined, I therefore forewarn you that you should simply believe spiritually concerning the unity of substance, and recognize the true Son from the true Father. But into the quality of the matter you ought not to enquire: for God willed to be believed, not to be judged, nor examined; for of what kind or how great He is cannot be known. For this the Prophets, this the Apostles preached. Then, according to our capacity, according to our strength, according to our faith, let us look at what God is: and let us see whether anything can be compared to Him. Certainly God is this: that which, even when it is spoken, cannot be spoken; when it is assessed, cannot be assessed; when it is compared, cannot be compared; when it is defined, grows by the very definition: He who covers heaven with His hand, encloses the whole circuit of the world in His fist; Whom all things do not know in His entirety, and yet know by fearing Him; to Whose name and power this world is in service, and the very momentary alternation of the elements succeeding one another bears witness to itself that it must serve.
2. Filii diversa nomina. Singulorum rationes. Videte ergo, si potest aliquid esse, cui possit Pater et Filius comparari, quia talis est Filius qualis et Pater. Non enim ipse cum Patre unum se diceret, nisi talem se de Patre, qualis est Pater, sciret. Ratio quaedam, quae apud Graecos λόγος nuncupatur, quae inter Patrem et Filium personas vel vocabula distinguit, quia et ipse Filius ratio dicitur: quae tamen ratio multis nominibus appellatur, modo verbum, modo virtus, modo sapientia, modo dextera, modo brachium, modo margarita, modo thesaurus, modo retia, modo aratrum, modo fons, modo petra, modo lapis angularis, modo homo, modo agnus, modo vitulus, modo aquila, modo leo, modo via, veritas et vita, cum sit Deus omnia in omnibus: ut per haec vocabula divinarum dispositionum mysteria cognoscantur, non ut ipsa majestas Filii Dei proprie definita monstretur. Hoc enim Filius Dei, quod Pater est, non aliud, id est, per quem omnia facta sunt. Nam et hoc Verbum nuncupatur; quia semper in Patre, et de Patre, et nihil Pater sine eo jussit aut fecit. Virtus dicitur, quia proprie de Deo est, et omnis potestas in ipso consistit. Sapientia appellatur, quia non aliunde quam de Patre veniens, credentibus arcana coelestia reseravit. Dextera nuncupatur, quia per eum omnia divina opera perfecta sunt. Brachium dicitur, quia ab ipso omnia continentur. Margarita appellatur, ut nihil eo pretiosius habeatur. Thesaurus dicitur, quia in ipso omnes opes, divitiae coelestium regnorum reconditae cognoscuntur. Retia dicitur, quia per ipsum et in ipso de mari saeculi diversarum gentium multitudo, more piscium, per Baptismum in Ecclesia congregatur, ubi bonorum malorumque discrimen agnoscitur. Aratrum nuncupatur, quia signo crucis ejus dura pectora subjugantur, ut necessario semini praeparentur. Fons aquae vivae appellatur, quia ex eo sitientia corda coelestis aquae gratia irrigantur. Petra dicitur, quia credentibus fortitudinem, incredulis duritiam praestat. Lapis angularis dicitur, quia utrosque parietes Novi et Veteris Testamenti ipse unus et mediator in semetipso continens, copulavit. Agnus appellatur, ut innocentia et passio Christi demonstretur. Homo dicitur, quia secundum carnem propter nos homines nasci dignatus est. Vitulus dicitur, quia propter nostram salutem immolari sustinuit. Aquila dicitur, quia post venerabilem resurrectionem ad Patris sui revolavit sedem. Leo est dictus, quia ipse est rex regum, quia mortem ac diabolum virtutis suae potestate comminuit. Via est, quia per ipsum ad Patrem accessus est. Veritas est, quia mendacium nescit. Vita est, quia dat vitam. Ipse universa significat.
2. The diverse names of the Son. The reasons for each. See therefore whether there can be anything to which the Father and the Son can be compared, since the Son is such as the Father also is. For He would not say that He is one with the Father, unless He knew Himself to be, from the Father, such as the Father is. A certain Reason, which among the Greeks is called λόγος, which distinguishes the persons or names between Father and Son, since the Son Himself too is called Reason: yet this Reason is called by many names, now Word, now Power, now Wisdom, now right hand, now arm, now pearl, now treasure, now nets, now plough, now fountain, now rock, now cornerstone, now man, now lamb, now calf, now eagle, now lion, now way, truth and life, since God is all in all: so that through these names the mysteries of the divine dispensations may be known, not so that the very majesty of the Son of God may be shown properly defined. For the Son of God is this, what the Father is, nothing else, that is, He through Whom all things were made. For He is also called Word because He is always in the Father, and from the Father, and the Father commanded or made nothing without Him. He is called Power, because He is properly from God, and all might consists in Him. He is called Wisdom, because, coming from nowhere else than from the Father, He has unlocked heavenly secrets to believers. He is named the right hand, because through Him all divine works have been accomplished. He is called the arm, because all things are held together by Him. He is called a pearl, so that nothing may be held more precious than He. He is called treasure, because in Him all wealth, the riches of the heavenly kingdoms, are known to be stored up. He is called nets, because through Him and in Him the multitude of diverse nations is gathered out of the sea of the world, after the manner of fish, through Baptism into the Church, where the distinction between good and bad is recognized. He is named a plough, because by the sign of His cross hard hearts are brought under the yoke, so that they may be made ready for the necessary seed. He is called a fountain of living water, because from Him thirsting hearts are watered by the grace of heavenly water. He is called a rock, because He provides strength to believers, hardness to unbelievers. He is called the cornerstone, because, Himself one and the mediator, holding together in Himself both walls, of the New and of the Old Testament, He joined them. He is called a lamb, so that the innocence and passion of Christ may be shown. He is called man, because according to the flesh He deigned to be born for us men. He is called a calf, because for our salvation He endured to be sacrificed. He is called an eagle, because after His venerable resurrection He flew back to the seat of His Father. He is said to be a lion, because He is King of kings, because He crushed death and the devil by the might of His power. He is the way, because through Him there is access to the Father. He is the truth, because He knows no lie. He is the life, because He gives life. He signifies all things.
