The Word through whom all things were made
Augustine is explaining the first article of the creed about God the Father almighty, and now moves to the second article about the Son, the Word through whom all things were made.
Therefore, since we believe in God the Father almighty, we must hold that no creature exists that was not created by the Almighty. And because he created all things through the Word—the Word who is also called the truth and the power and the wisdom of God, and who is commended to our faith under many other names as Jesus Christ our Lord, that is, our liberator and ruler, the Son of God—for that Word through whom all things were made could be begotten by none except the one who made all things through him—we believe also in Jesus Christ, the only Son of God the Father, that is, his unique one, our Lord.
But we must not understand that Word as we understand our own words, which are produced by voice and mouth, strike the air, and pass away, lasting no longer than their sound. That Word remains unchangeably. For it was said of him when Scripture spoke of wisdom: “Remaining in herself, she renews all things” (Wisdom of Solomon 7:27). He is called the Word of the Father because through him the Father becomes known. Just as when we speak true words, we act so that our mind becomes known to the hearer, and whatever secret we carry in our heart is brought to another's knowledge through signs of this kind, so wisdom whom God the Father begot is most fittingly named his Word, because through her the most hidden Father becomes known to worthy souls.

Credentes itaque in deum patrem omnipotentem nullam creaturam esse, quae ab omnipotente non creata sit, existimare debemus. et quia omnia per uerbum creauit, quod uerbum et ueritas dicitur et uirtus et sapientia dei multisque aliis insinuatur uocabulis qui nostrae fidei Iesus Christus dominus commendatur, liberator scilicet noster et rector filius dei — non enim uerbum illud, per quod sunt omnia condita, generare potuit nisi ille, qui per ipsum condidit omnia -
credimus etiam in Iesum Christum filium dei patris unigenitum, id est unicum, dominum nostrum. quod tamen uerbum non sicut uerba nostra debemus accipere, quae uoce atque ore prolata uerberato aere transeunt nec diutius manent quam sonant; manet enim illud uerbum incommutabiliter. nam de ipso dictum est, cum de sapientia diceretur: in se ipsa manens innouat omnia. uerbum enim patris ideo dictum est, quia per ipsum innotescit pater. sicut enim uerbis nostris id agimus, cum uerum loquimur, ut noster animus innotescat audienti et quidquid secretum in corde gerimus per signa huius modi ad cognitionem alterius proferatur: sic illa sapientia, quam deus pater genuit, quoniam per ipsam innotescit dignis animis secretissimus pater, uerbum eius 'conuenientissime nominatur.
