Is it something that has yet to come? And who gets anything put on their forehead? Might it be a bandana? Very strange. Here are a couple of verses from Revelations that discusses the "mark of the beast".
Revelation 13:16-17
And he causes all, the small and the great, and the rich and the poor, and the free men and the slaves, to be given a mark on their right hand or on their forehead, and he provides that no one will be able to buy or to sell, except the one who has the mark, either the name of the beast or the number of his name.
Revelation 14:9-10
Then another angel, a third one, followed them, saying with a loud voice, “If anyone worships the beast and his image, and receives a mark on his forehead or on his hand, he also will drink of the wine of the wrath of God, which is mixed in full strength in the cup of His anger; and he will be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb.

The entire book of Revelation speaks in terms of imagery.
This is deliberate because imagery can carry multiple meanings and associations. No study of Revelation can be complete without a parallel study of the book of Daniel. Daniel provides a template or pattern for understanding the textual imagery used by God's Word. If you learn from Danial you can understand Revelation.
One of the principles of interpretation for Daniel and Revelation suggests that use of a human-animal hybrid is a reference to Systems, Nations or Religions.
The book of Revelation makes numerous references to two beasts. One rises from the sea and the other inhabits land. The sea beast is defined as the Roman Catholic church. It is not a man because it is a religion that arises from all the people of the world (Rev 17:15). It sits upon seven hills (Rome) and it utters blaspheme (claims to be God) and seeks to change dates and times. (Daniel 7:25)
"
The Pope and God are the same, so he has all power in heaven and earth."
Barclay Cap. XXVII, p. 218. Cities Petrus Bertrandus, Pius V.
We observe Sunday instead of Saturday because the Catholic Church transferred the solemnity from Saturday to Sunday.” -Rev. Peter Geiermann C.SS.R., The Convert’s Catechism of Catholic Doctrine, p. 50
The mark of the [religious] beast is seen on the hand and forehead. It isn't a tattoo and it isn't a computer chip. A mark on the head signifies ALLEGIANCE to the beast, to the religion. A mark on the hand, signifies ACTION taken in support of the beast, of the religion. This interpretation was understood to mean the RCC by the fathers of the Protestant Reformation, but at the end of the 16th century the RCC published a response (doctrines of demons) that has been accepted by the Protestant church without question or hesitancy.
It was originally called FUTURISM by its author Francisco Ribera, a Roman Catholic Jesuit priest. In the mid-19th century it was revived and given the new name DISPENSATIONALISM by John Nelson Darby. The post Civil War American protestant population embraced it and adopted it as gospel. Ultimately the dogma has clouded and misdirected believers ever since. Basically the doctrine suggests that the End Times would not happen until some distant point in the future and definitely would not involve the Catholic Church.
However, Revelation 13 predicts the death of a Pope and the subsequent restoration of the Vatican in Rome itself.
------History---------------[look this up]------------
Head wound - death of a Pope
(a horn or horns on a human-animal hybrid can be interpreted as a leader or succession of leaders)
In 1796, during the French Revolutionary Wars, French troops under Napoleon Bonaparte invaded Rome and captured Pope Pius VI, taking him as a prisoner to Valence France, where he died in 1799.
Healing the wound.....
The Lateran Treaty, also called Lateran Pact of 1929, treaty (effective June 7, 1929, to June 3, 1985)
The Lateran Pacts signed by Mussolini on 11 February 1929, had three parts: a political treaty (giving the Vatican its own micro-state), a financial convention (giving the Vatican reparations) and a concordat (giving privileges within Italy, for instance by letting the Church influence public education).
Recent history proves the book of Revelation focuses upon the RCC as the anti-Christ religion, which will be betrayed and destroyed by the same people it deluded.
The mark of the [religious] beast is therefore ALLEGIANCE to it and ACTION to support it.
that's me, hollering from the choir loft....
