"And if it is a mystery, then we, too, had the right to preac..." — Fyodor Dostoyevsky quote meaning

And if it is a mystery, then we, too, had the right to preach mystery and to teach them that it is not the free choice of the heart that matters, and not love, but the mystery, which they must blindly obey, even setting aside their own conscience. And so we did. We corrected your deed and based it on miracle, mystery, and authority. And mankind rejoiced that they were once more led like sheep, and that at last such a terrible gift, which had brought them so much suffering, had been taken from their hearts.
