Context: Isidore explains Christ's command to be wise as serpents and innocent as doves.
On the text, "Be wise as serpents and innocent as doves" [Matthew 10:16]. The Lord commands us to be wise like the serpent, preserving our head — that is, our faith — in every trial. For no matter how many dangers and blows the serpent endures, it keeps its head unharmed. And again, by a kind of cunning it sheds its old skin by squeezing through a narrow passage, casting off its age. The Lord wants us likewise, through the narrow way, to strip off the old self and put on the new. But he also commands the innocence of the dove — because cunning without innocence is mere deceit, and innocence without cunning is mere foolishness. The two must go together: sharp enough to see through evil, simple enough never to practice it.
