John also saw. Revelation. 13-
1- And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
 7 heads are the Christian denominations, who slander the good name of Christ and the Church.
Their 10 horns with diadems are now the antichrists, the substitutes of Christ (intermediary between God and men). 
In Rev. 13 and 17- speaks of the beast of 2 horns (The woman riding the beast), that starts back there in the past and finishes at the end, as in Rev.17:
9- And here [is] the mind which hath wisdom. The seven heads are seven mountains, on which the woman sitteth. (Woman, Catholic Church, mother and daughters). 
The seven mounts are all high places in earth; you only have to look in every city or place there is one or more luxurious temple of the beast, a cathedral, with two towers as a symbol of the domain of the two horn beast, or one, of the Pope, who prevailed until the arrival of the antichrist of the end, who

speaks in Rev. 17:
10- And there are seven kings: five are fallen, and one is, [and] (o Papa), the other is not yet come; and when he cometh, he must continue a short space. (The great leader of all, the antichrist of the end)
11- And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition.    The Pope, father of all the other horns, Who commands priests, bishops, pastors and leaders who turned sons of the Devil, Who create and lead the thousands (of heads) of denominations of Christian religion.
In Revelation 13, speaks that the dragon passed his glory of the kingdom of the beast.
2- (...) and the dragon gave him his power, and his seat, and great authority.
4- And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who [is] like unto the beast? who is able to make war with him?
5- And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty [and] two months. (1 day is = 1 year = 1260 years).
