What's in a name?

The significance of Pope Leo XII provides us with a clue. See here.

On the Feast of the Apparition of Saint Michael:

St. Michael the Archangel, 

defend us in battle. 

Be our defense against the wickedness and snares of the Devil. 

May God rebuke him, we humbly pray, 

and do thou, 

O Prince of the heavenly hosts, 

by the power of God, 

thrust into hell Satan, 

and all the evil spirits, 

who prowl about the world 

seeking the ruin of souls. Amen. .

O glorious prince St. Michael, 

chief and commander of the heavenly hosts, 

guardian of souls, vanquisher of rebel spirits, 

servant in the house of the Divine King

and our admirable conductor, 

you who shine with excellence

and superhuman virtue deliver us from all evil,

who turn to you with confidence

and enable us by your gracious protection

to serve God more and more faithfully every day.

"Satan will appear without the Cross, as the Great Philanthropist and Social Reformer.."

In his Life of Christ (Image Books, 1977, p. 10), Archbishop Fulton John Sheen wrote, "We do know that at the end of time, when the great conflict between the forces of good and evil takes place, Satan will appear without the Cross, as the Great Philanthropist and Social Reformer to become the final temptation of mankind." Indeed, Paul Henri-Spaak, who served as Belgian Prime Minister and gained international prominence in 1945 when he was elected chairman of the first session of the General Assembly of the United Nations, had called for such a "Great Philanthropist and Social Reformer":

"We do not want another committee, we have too many already. What we want is a man of sufficient stature to hold the allegiance of all people, and to lift us out of the economic morass in which we are sinking. Send us such a man* and be he God or the Devil, we will receive him."

It would seem that the world is ready to receive such a man. Read this article and watch the commercials which have appeared on CNN.

* St. John of the Cleft Rock (14th century): "It is said that twenty centuries after the Incarnation of the Word, the Beast in its turn shall become man. About the year 2000 A.D., Antichrist will reveal himself to the world."
