The Son Took Flesh and Bone to His Person

Anselm on the person of Christ ("On the Incarnation of the Word" in Anselm of Canterbury: The Major Works; Oxford: Oxford University Press, 1998):

For one who correctly understands the Son's incarnation believes that the Son assumed a human being into the unity of his person and not into the unity of his substance. And my adversary foolishly thinks that the Son assumed a human being into the unity of his substance rather than into the unity of his person (p. 249).

The glorious doctrine of the person of Christ is worth celebrating with all the might: and so it also one of those doctrines worth fighting over when it is under attack.
