Demote Christ? You are mistaken. The text said:
The exorcist confirmed that Satan's great foe is the Virgin Mary.Mo> I replied:
Actually it is Jesus Christ.
Mary is not greater than Christ. Catholics believe that as well. I respect what the exorcist is doing, but there is no way anyone is going to tell me Satan fears Mary more than God.
Genesis chapter 3. Protestant version with explanation.
14 And the Lord God said to the serpent: Because thou hast done this thing, thou art cursed among all cattle, and beasts of the earth: upon thy breast shalt thou go, and earth shalt thou eat all the days of thy life. 15 I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel.
15 “She shall crush”... Ipsa, the woman; so divers of the fathers read this place, conformably to the Latin: others read it ipsum, viz., the seed. The sense is the same: for it is by her seed, Jesus Christ, that the woman crushes the serpent’s head.
