From Luther’s Table Talk #189

We cannot vex the devil more than by teaching, preaching, singing and talking of Jesus. Therefore I like it well, when with sounding voice we sing in the church: Et homo factus est; et verbum caro factum est. The devil cannot endure these words, and flies away, for he well feels what is contained therein. Oh, how happy a thing were it, did we find as much joy in these words as the devil is affrighted at them. But the world condemns God’s words and works, because they are delivered to them in a plain and simple manner. Well, the good and godly are not offended therewith, for they have regard to the everlasting celestial treasure and wealth which therein lies hid, and which is so precious and glorious, that the angels delight in beholding it. Some there are who take offence, that now, and then in the pulpits we say: Christ was a carpenter’s son, and as a blasphemer and rebel, he was put on the cross, and hanged between two malefactors.

But seeing we preach continually of this article, and in our children’s creed, say: That our Saviour Christ suffered under Pontius Pilate, was crucified, dead, and buried, etc., for our sins, why, then, should be not say Christ was a carpenter’s son? especially seeing that he is clearly so named in the gospel, when the people wondered at his doctrine and wisdom, and said: “How cometh this to pass? Is not this the carpenter, the son of Mary?” (Mark, vi.)

Et verbum caro factum est. The Word became Flesh. Nothing in scripture is more amazing than this.
