“Behold, I send you out as sheep in the midst of wolves. Therefore be wise as serpents and harmless as doves.” Matthew 10:16
Let us then be ashamed, who do the contrary, who set like wolves upon our enemies. For so long as we are sheep, we conquer: though ten thousand wolves prowl around, we overcome and prevail. But if we become wolves, we are worsted, for the help of our Shepherd departs from us: for He feeds not wolves, but sheep: and He forsakes thee, and retires, for neither dost thou allow His might to be shown. Because, as He accounts the whole triumph His own, if thou being ill used, show forth gentleness; so if thou follow it up and give blows, thou obscurest His victory.
Homily on Matthew 10:16
I somehow have a sense that this has something to say about Christians and the internet./THB
