it was on Mt. Carmel that Elijah battled the prophets of the false god Baal (1 Kings 18). They spent hours calling on their idol to consume the sacrifice they had prepared, but to no avail. Elijah prepared his own sacrifice, prayed to God, and was rewarded by having fire come from heaven to consume the sacrifice. The Israelites were inspired by this to return to the Lord.
Carmel’s history as a place of spiritual battle also reveals something to us about Mary: namely, that she is willing to fight for the salvation of her children, as manifested in her promise to St. Simon Stock: whatever the manner of vice and sin that someone mires himself in, Mary will aid him in breaking free from it.
