4. Maria credendo concepit sine viro. Christus nostri gratia natus est in carne. Credimus ergo in Jesum Christum Dominum nostrum, natum de Spiritu sancto ex virgine Maria. Nam et ipsa beata Maria, quem credendo peperit, credendo concepit. Cum enim promisso sibi filio, quaesisset quemadmodum fieret, quoniam virum non cognosceret; utique solus ei modus cognoscendi atque pariendi notus erat, quem quidem ipsa experta non fuerat, sed ex aliis feminis natura frequentante didicerat, ex viro scilicet et femina hominem nasci: responsum ab Angelo accepit, Spiritus sanctus superveniet in te, et virtus Altissimi obumbrabit tibi; propterea quod nascetur ex te Sanctum, vocabitur Filius Dei. Quae cum dixisset Angelus, illa fide plena, et Christum prius mente quam ventre concipiens, Ecce, inquit, ancilla Domini, fiat mihi secundum verbum tuum (Luc. I, 34-38). Fiat, inquit, sine virili semine conceptus in virgine; nascatur de Spiritu sancto et integra femina, in quo renascatur de Spiritu sancto integra Ecclesia. Sanctum quod nascetur de homine matre sine homine patre, vocetur Dei Filius; quoniam qui natus est de Deo Patre sine ulla matre, mirabiliter oportuit ut fieret hominis filius; in ea carne natus, ut per clausa viscera parvus exiret, in qua resuscitatus per clausa ostia magnus intraret. Mira sunt haec, quia divina sunt; ineffabilia, quia et inscrutabilia: non sufficit explicando os hominis, quia nec investigando cor hominis. Credidit Maria, et in ea quod credidit factum est. Credamus et nos, ut et nobis possit prodesse quod factum est. Quamvis ergo mirabilis sit etiam ista nativitas: tamen cogita, o homo, quid pro te Deus tuus, Creator pro creatura susceperit; ut Deus in Deo manens, aeternus cum aeterno vivens, aequalis Filius Patri, pro reis et pro peccatoribus servis formam servi non dedignaretur induere. Neque enim hoc meritis humanis est exhibitum. Nam pro iniquitatibus nostris poenas potius merebamur: sed si iniquitates observasset, quis sustinuisset? Pro impiis ergo et pro peccatoribus servis Dominus factus est homo, de Spiritu sancto et virgine Maria nasci dignatus est.
4. Mary by believing conceived without a man. Christ for our sake was born in the flesh. We believe, therefore, in Jesus Christ our Lord, born of the Holy Spirit from the Virgin Mary. For the blessed Mary herself conceived by believing Him Whom she bore by believing. For when a son had been promised her and she had asked how this would come about, since she did not know a man (for of course the only manner of conceiving and giving birth known to her was one which she herself had not experienced, but had learned from other women, nature repeating it, namely that a human being is born of a man and a woman), she received the answer from the Angel: The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the Holy One that will be born of you will be called the Son of God. When the Angel had said this, she, full of faith, and conceiving Christ in her mind before her womb, said: Behold the handmaid of the Lord; be it done to me according to your word (Luke 1:34–38). Let it be done, she says: a conception in a virgin without a man's seed; let Him be born of the Holy Spirit and of an untouched woman, in Whom the untouched Church may be reborn of the Holy Spirit. Let the Holy One Who will be born of a human mother without a human father be called the Son of God; for it was fitting that He Who was born of God the Father without any mother should wondrously become the son of a human being; born in that flesh, so that as a little one He might come forth through a closed womb, in which, raised again, He might as a great one enter through closed doors. These things are wonderful, because they are divine; unspeakable, because also unsearchable: the mouth of man does not suffice to explain them, because neither does the heart of man suffice to search them out. Mary believed, and in her what she believed was done. Let us too believe, so that what was done may also be of profit to us. Although, then, this birth too is wonderful, yet consider, O man, what your God took upon Himself for you, the Creator for the creature: that God, abiding in God, the eternal living with the eternal, the Son equal to the Father, did not disdain to put on the form of a servant for guilty and sinful servants. For this was not bestowed on human merits. For on account of our iniquities we rather deserved punishments: but if He had observed iniquities, who would have endured? For the ungodly, therefore, and for sinful servants the Lord was made man, and deigned to be born of the Holy Spirit and the Virgin Mary.
5. Pro nobis mortuus. Crux non erubescenda. Parum hoc forsitan videatur, quod pro hominibus Deus, pro peccatoribus justus, pro reis innocens, pro captivis rex, pro servis Dominus carne humanitatis indutus advenit, in terris visus est et cum hominibus conversatus est: crucifixus insuper, mortuus et sepultus est. Non credis? Dicis forte: Quando hoc factum est? Audi quo tempore: sub Pontio Pilato. In significatione tibi etiam nomen judicis positum est, ne vel de tempore dubitares. Crede ergo Filium Dei crucifixum sub Pontio Pilato et sepultum. Majorem autem hac charitatem nemo habet, ut animam suam ponat quis pro amicis suis (Joan. XV, 13). Putas, nemo? Omnino nemo. Verum est, Christus hoc dixit. Interrogemus Apostolum, etiam respondeat nobis.
5. He died for us. The cross not to be blushed at. This may perhaps seem little: that God for men, the just for sinners, the innocent for the guilty, the king for captives, the Lord for servants came clothed in the flesh of humanity, was seen on earth and conversed with men; moreover He was crucified, died and was buried. You do not believe? Perhaps you say: When was this done? Hear at what time: under Pontius Pilate. For a sign to you even the name of the judge has been set down, so that you should not doubt even about the time. Believe, therefore, that the Son of God was crucified under Pontius Pilate and buried. But greater love than this no one has, that one lay down his life for his friends (John 15:13). Do you think: no one? No one at all. It is true; Christ said this. Let us question the Apostle; let him too answer us.
