St. John of Damascus concurred. As would have every single Christian, Anglicans included, before the present PC, feel-good, braindead, "nice" century.
I was ordained with a godly and insightful young man who has gone on to be ordained as a priest. Like all well-meaning Anglicans who want to "Welcome Refugees", he recently opined that the risk of letting so many more Muslims into the West is "worth it." He and I had some interesting exchanges in the wake of that comment, and I truly do believe he is rethinking his opinion.
All we have to do is look at Christian history, and then consider more reflectively what we are now seeing in order to come to another conclusion: it is most certainly not "worth it."
