Daemoniac

one "possessed with a devil." In the days of our Lord and his
apostles, evil spirits, "daemons," were mysteriously permitted
by God to exercise an influence both over the souls and bodies
of men, inflicting dumbness (Matt. 9:32), blindness (12:22),
epilepsy (Mark 9:17-27), insanity (Matt. 8:28; Mark 5:1-5).
Daemoniacs are frequently distinguished from those who are
afflicted with ordinary bodily maladies (Mark 1:32; 16:17, 18;
Luke 6:17, 18). The daemons speak in their own persons (Matt.
8:29; Mark 1:23, 24; 5:7). This influence is clearly
distinguished from the ordinary power of corruption and of
temptation over men. In the daemoniac his personality seems to
be destroyed, and his actions, words, and even thoughts to be
overborne by the evil spirit (Mark, l.c.; Acts 19:15).
