Who has the WT organization taught is the "antichrist"?
SS2 The Time Is At Hand
We need not look long to find a character fitting all the requirements perfectly; one whose record, written by secular historians as well as by its own deluded servants, we shall see agrees exactly with the prophetic delineations of Antichrist. But when we state that the one and only system whose history fits these prophecies is Papacy, let no one misunderstand us to mean that every Roman Catholic is a man of sin; nor that the priests, nor even the popes of the Church of Rome, are, or have been, the Antichrist. No man is " the Antichrist," "the Man of Sin," described in prophecy. Popes, bishops and others are at most only parts or members of the Antichrist system, even as all of the Royal Priests are only members of the true Christ, under Jesus their head, and in the same manner that these in their present condition are together the antitypical Elijah, though no one of them is the Elijah or the Christ foretold. Notice, further, that the Church of Rome as an ecclesiastical system only is not the " Man of Sin," and is never presented under any figure of a man . On the contrary, a woman is always the symbol used for a church separate from its head and lord. The true Church is symbolized by a "chaste virgin," while the apostate church, which has fallen away from primitive purity and fidelity to the Lord, is symbolically called "a harlot." As the true "virgin" Church continues to be such to the end of the age, when she is to be united to her Lord and take his name--Christ--so the apostate church was not the Antichrist, or Man of Sin, until she united with her lord and head, the pope, the claimed vicegerent of Christ, and became a religious empire , falsely styled Christendom--which signifies Christ's Kingdom.

The fact is that, while Papacy holds all her old errors of doctrine and is, therefore, as much as ever the Antichrist* of Scripture, she has been forced to more civilized methods during the past century.
SS6 The New Creation
It was not long after the apostles fell asleep, we may be sure, until the spirit of rivalry under the guidance of the Adversary led step by step to the ultimate organization of the great Antichrist system--Papacy.

Identification. Although there has been much effort in the past to identify "the antichrist" with an individual, such as Pompey, Nero, or Muhammad (this latter person being suggested by Pope Innocent III in 1213 C.E.), or with a specific organization, as in the Protestant view of "the antichrist" as applying to the papacy, John’s inspired statements show the term to be broad in its application, embracing all those who deny that "Jesus is the Christ," and who deny that Jesus is the Son of God who came "in the flesh."—1Jo 2:22; 4:2, 3; 2Jo 7, NE,NIV; compare Joh 8:42, 48, 49; 9:22.
