He frequently transforms the earth into a barren wasteland, causing those who depart from the Church to foster hostility against it. The Evangelist John notes: ‘They went out from us, but they were not of us; for if they had been of us, they would have continued with us’ (1 John 2:19). The cities of Judea are left desolate while the gatherings of heretics thrive. Thus, if an individual proves to be the champion and instigator of false teachings, it can rightfully be proclaimed: the lion has emerged from his den, and the plunderer of nations has arisen, and so on.
