159:1
In Christo Deus et homo, non alter, sed ipse: non duo ex diversis, sed unus ex utroque mediator. Gemina quidem substantia, sed una persona est. Quam soliditatem si quis scindere dualitate præsumat, primum est quod publice contra Apostoli sententiam profitetur, dicentem: Unus mediator Dei et hominum Christus Jesus ( I Tim. II, 5). Deinde eligat necesse est de duobus, id est divina humanaque, quam naturam mediationis hujus velit mysteria suscepisse. Si solus Deus mediator, non est alius apud quem intercedat: si solus homo, non est qui reconciliare prævaleat. Junge porro ut sit (II Cor. v, 19) Deus in Christo, et est mundum reconcilians sihi.
In Christ, God and man, not another but Himself: not two out of diverse things, but one Mediator out of both. The substance indeed is twofold, but the person is one. And if anyone should presume to sever this solidity by a duality, first there is the fact that he publicly professes against the sentence of the Apostle, who says: «One Mediator of God and men, Christ Jesus» (1 Tim. 2:5). Then he must needs choose, out of the two, that is, the divine and the human, which nature he would have this mediation to have undertaken its mysteries. If God alone is the Mediator, there is no other with whom He intercedes: if man alone, there is none who can prevail to reconcile. Join them, moreover, that there may be (2 Cor. 5:19) «God in Christ,» and it is «reconciling the world to Himself.»
在基督裡，神與人，不是另一位，乃是祂自己：不是由不同之物而成的兩者，乃是由二者合成的一位中保。本體固然是雙重的，但位格卻是同一個。若有人膽敢用二元性割裂這穩固合一，首先，他就是公然背離使徒的判語而作宣認，因使徒說：「在神和人中間，只有一位中保，乃是……基督耶穌」（提前二5）。其次，他勢必要從二者中，即神性與人性中，選定他要這中保的奧祕是由哪一種性所承擔的。若惟獨神是中保，就沒有另一位可供祂代求：若惟獨人是中保，就沒有一位能有力使人與神和好。反之，將二者聯合，使有（林後五19）「神在基督裡」，這便是「叫世人與自己和好」。
159:2
Ipse videlicet penes quem agendum est, ipse qui agat: sic idem missus, et idem regressus; sicut ipse judicatus, et ipse judicaturus.
He, namely, in whose presence the matter must be transacted, is Himself the one who transacts it: thus the same is sent, and the same returns; even as He Himself is judged, and He Himself shall judge.
祂，即那在其面前必須處理此事的一位，自己就是那處理此事者：如此，被差遣的是同一位，回歸的也是同一位；正如祂自己受審判，祂自己也將要施行審判。
