What is ‘The Exsultet‘ or ‘Easter Proclamation’?

"The Time That Pope Francis In St. Peter’s Square At The Vatican Declared To The Entire World That Lucifer Is The God Of The Catholic Church

What was so special about this ceremony to go to all that expense and trouble? What was it that the pope needed the entire world to watch? As it turns out, Pope Francis was about to declare that Lucifer is the Morning Star, a title that the Bible gives to Jesus Christ alone. The pope was telling all the world that Lucifer is God! The highlight of the ceremony was the singing of a Catholic prayer known as ‘The Exsultet‘, or ‘Easter Proclamation’."

"Pope Francis and the Vatican has introduced the world to their god they’ve been worshipping all along, Lucifer. According to Pope Francis and the Catholic Church, The Morning Star is the creator of the world and the father of Christ. He brought "light" to the human race."

Vatican Openly Declares Lucifer As God At Catholic Mass?

"Some have claimed that “the pope’s deacon” invoked Lucifer and described Jesus as the devil’s Son.

This claim is based on translating part of the Easter Vigil liturgy this way:

Flaming Lucifer who finds mankind;
I say O Lucifer, who will never be defeated.
Christ is your Son, who came back from Hell;
shed his peaceful light and is alive and reigns in the world without end.

What’s the real story?

The pope does not have a personal deacon, though deacons can sing the part of the Easter Vigil liturgy known as the Exsultet, Easter Proclamation, or Paschal Proclamation. (Exsultet is its first word in Latin: “Let them exult!”)"
