He understands that all the blasphemers, and atheists, and free-thinkers, and so on that ever assailed the bastions of the church of God could not do one tenth as much mischief to her as those who pretend to be followers of the bleeding Lamb, and in secret are crucifying the Lord afresh, and putting him to an open shame.1
