3. We will offer later an explanation of these texts in the words of the Gospels and Epistles themselves. But first we hold it right to remind the members of our common faith, that the knowledge of the Eternal is presented in the same confession which gives eternal life463    Alluding to St. John xvii. 3, quoted in c. 2.. He does not, he cannot know his own life, who is ignorant that Christ Jesus was very God, as He was very man. It is equally perilous, whether we deny that Christ Jesus was God the Spirit, or that He was flesh of our body: Every one therefore who shall confess Me before men, him will I also confess before My Father which is in Heaven. But whosoever shall deny Me before men, him will I also deny before My Father which is in heaven464    St. Matt. x. 32, 33.. So said the Word made flesh; so taught the man Jesus Christ, the Lord of majesty, constituted Mediator in His own person for the salvation of the Church, and being in that very mystery of Mediatorship between men and God, Himself one Person, both man and God. For He, being of two natures united for that Mediatorship, is the full reality of each nature; while abiding in each, He is wanting in neither; He does not cease to be God because He becomes man, nor fail to be man because He remains for ever God. This is the true faith for human blessedness, to preach at once the Godhead and the manhood, to confess the Word and the flesh, neither forgetting the God, because He is man, nor ignoring the flesh, because He is the Word.

3. Christus et Deus est et homo. Attendant Nestorius et Eutyches.---Atque horum quidem superius memoratorum rationem ex ipsis vel evangelicis vel apostolicis professionibus praestituri, admonendos esse omnes communis fidei existimamus: ut in qua confessione aeternitas vitae est, in eadem sit intelligentia aeternitatis . Nescit plane vitam suam, nescit, qui Christum Jesum ut verum Deum ita et verum hominem ignorat. Et ejusdem periculi res est, Christum Jesum vel Spiritum Deum, vel carnem nostri corporis denegare. Omnis ergo qui confitebitur me coram hominibus, confitebor et ego eum coram 0282C patre meo, qui est in coelis. Qui autem negaverit 0283A me coram hominibus, negabo et ego eum coram patre meo, qui est in coelis. Haec Verbum caro factum loquebatur, et homo Jesus Christus Dominus majestatis docebat: Mediator ipse in se ad salutem Ecclesiae constitutus, et 260 illo ipso inter Deum et homines mediatoris sacramento utrumque unus exsistens, dum ipse ex unitis in idipsum naturis, naturae utriusque res eadem est; ita tamen, ut neutro careret in utroque, ne forte Deus esse homo nascendo desineret, et homo rursum Deus manendo non esset. Haec itaque humanae beatitudinis fides vera est, Deum et hominem praedicare, Verbum et carnem confiteri: neque Deum nescire quod homo sit, neque carnem ignorare quod Verbum sit.
