5.4 The third Pope sells out and allies himself with the Anti-Christ

Lighting in Burgundy will reveal portentous events.
A thing that could never have been done by trickery.
The lame priest will reveal
matters of the Senate to the enemy. (II-76)

This particular pope has his ecclesiastical roots in Burgundy. If he had his preferences, he would prefer to have the Papacy based in France rather than in the Vatican. When the last pope changes his loyalties from the church to the Anti-Christ an explosion of a fantastic, very advanced satellite will be caused. The Vatican could be able to see that the traitor was in its own inner and high ups sources when that horrible accident had already been past. Treachery had come from «Burgundy».
The last pope who is of service to the Anti-Christ voluntarily contributes the inner resources of the information that he, as pope, has access to. Information that the Anti-Christ could not have gotten in a million years just through his spies:

The great star will burn for seven days
and the cloud will make the sun appear double.
The large mastiff will howl all night
when the great pontiff changes his abode. (II-41)

«The great pontiff changing his abode» refers to the last pope who changes his loyalties from the church to the Anti-Christ. «The great star burning for seven days» refers to the explosion of a fantastic, very advanced, satellite which has its ancestry in the present day star wars programs. The satellite will explode and burn for seven days. It will burn so brightly that through the clouds caused by the explosion it will appear to be a second sun. «The mastiff that will howl all night» refers to a secret branch of the priesthood in the Catholic Church that no one knows about except a few high priest members.

This secret branch of the priesthood is like a private army, and the commander-in-chief is the pope. Their job is to fight for the church if the need should arise, similar to the way the Jesuits used to be the soldiers of Christ. The members of this particular order of priesthood will be very finely educated, trained in all of the martial arts and all ways of committing violence.
But when the pope sells out and allies himself with the Anti-Christ, it in effect leaves this army leaderless. What can they do but howl all night and try to figure out a solution? The evening of the same day the members of the select guard of the pope’s personal army, which has been left leaderless, will anxiously try all night to decide what to do.
