18. So we have made our reply to the folly of our violent opponents, merely to prove the emptiness of their falsehoods and so prevent them from misleading the unwary by the error of their vain and foolish statements. But the faith of the Gospel did not of necessity require our answer. The Lord prayed on our behalf for our union with God, but God keeps His own unity and abides in it. It is not through any mysterious appointment of God that they are one, but through a birth of nature, for God loses nothing in begetting Him from Himself. They are one, for the things which are not plucked out of His hand are not plucked out of the hand of the Father401 St. John x. 28, 29., for, when He is known, the Father is known, for, when He is seen, the Father is seen, for what He speaks the Father speaks as abiding in Him, for in His works the Father works, for He is in the Father and the Father in Him402 Ib. xiv. 7, 9, 10, 12.. This proceeds from no creation but from birth; it is not brought about by will but by power; it is no agreement of mind that speaks, it is nature; because to be created and to be born are not one and the same, any more than to will and to be able; neither is it the same thing to agree and to abide.
18. Unitas Filii et Patris diserte in Scripturis asserta.---Responsum igitur a nobis est stultitiae furentium, ad demonstrationem tantum inanis mendacii: ne imperitos fallerent vanae ac ridiculae assertionis errore. Caeterum fides evangelica responsionis nostrae necessitate non eguit. Unitatem nostram 0249C ad Deum Dominus pro nobis precatus est: suam vero 226 obtinet ille, et in ea manet. Nec per sacramentum dispensationis unum sunt, sed per naturae nativitatem, dum nihil in eo ex se Deus eum gignendo degenerat. Unum sunt, dum quae de manu ejus non rapiuntur, non rapiuntur de manu Patris (Joan. X, 28); dum eo cognito Pater cognitus est; dum eo viso Pater visus est; dum quae loquitur, manens in se Pater loquitur; dum in operante se operatur Pater; dum ipse in Patre est, et in eo Pater est (Joan. XIV, 0250A 7, 9, 10, 12). Hoc non praestat creatura, sed nativitas; non efficit voluntas, sed potestas; non loquitur unanimitas, sed natura: quia non unum est creari, et nasci; neque velle id ipsum est, quod et posse; neque concordare idem est, quod manere.
