On November 21, Catholics of Rome honor their bishop and pontiff Gelasius I.

The Catholic Encyclopedia says the following about him:

Pope Gelasius I (died 19 November 496) was Pope from 1 March 492 to his death in 496…

Despite all the efforts of the otherwise orthodox patriarch, Euphemius of Constantinople, and the threats and wiles by which the Emperor Anastasius tried to obtain recognition from the Apostolic See, Gelasius, though hard-pressed by difficulties at home, would make no peace that compromised in the slightest degree the rights and honor of the Chair of Peter. The constancy with which he combated the pretensions, lay and ecclesiastical, of the New Rome; the resoluteness with which he refused to allow the civil or temporal pre-eminence of a city to determine its ecclesiastical rank; the unfailing courage with which he defended the rights of the “second” and the “third” sees, Alexandria and Antioch, are some of the most striking features of his pontificate. It has been well said that nowhere at this period can be found stronger arguments for the primacy of Peter’s See than in the works and writings of Gelasius…

As a writer Gelasius takes high rank for his period. His style is vigorous and elegant, though occasionally, obscure. Comparatively little of his literary work has come down to us, though he is said to have been the most prolific writer of all the pontiffs of the first five centuries. There are extant forty-two letters and fragments of forty-nine others, besides six treatises, of which three are concerned with the Acacian schism, one with the heresy of the Pelagians, another with the errors of Nestorius and Eutyches, while the sixth is directed against the senator Andromachus and the advocates of the Lupercalia. The best edition is that of Thiel.
The feast of St. Gelasius is kept on 21 Nov., the anniversary of his interment, though many writers give this as the day of his death. (Murphy, J.F.X. (1909). Pope St. Gelasius I. In The Catholic Encyclopedia. New York: Robert Appleton Company. Retrieved April 21, 2014 from New Advent: http://www.newadvent.org/cathen/06406a.htm)

The reason I reported about him is because he is believed to have been the first pontiff to be referred to as the “vicar of Christ” (Park H. The Roman Catholic Church – A Critical Appraisal. Xulon Press, 2008, pp. 37-38). not because someone with my last name wrote the best edition about some heresy. However, I personally did write about early catholism in a documented way others have not (see Beliefs of the Original Catholic Church: Could a remnant group have continuing apostolic succession?).

That said, the word vicar comes from a Latin term:

vicar (n.)

early 14c., from Anglo-French vicare, Old French vicaire “deputy, second in command,” also in the ecclesiastical sense (12c.), from Latin vicarius “a substitute, deputy, proxy,” noun use of adjective vicarius “substituted, delegated,” from vicis “change, interchange, succession; a place, position” (see vicarious). The original notion is of “earthly representative of God or Christ;” but also used in sense of “person acting as parish priest in place of a real parson” (early 14c.). (http://www.etymonline.com/index.php?term=vicar viewed 0421/14)

So “Vicar of Christ” means In Substitute of Christ or Instead of Christ.

So what does the expression “anti-Christ” mean?

In English, the word Anti-Christ clearly means one who is opposed or against Christ. And that is consistent with the meaning in the Greek.

But the Greek allows for another definition that seems to be applicable.

The Greek term translated as anti, such as in antichrist in 1 John 2:18, is Strong’s word 473.

NT:473 άντί
anti (an-tee’); a primary particle; opposite, i.e. instead or because of (rarely in addition to):
(Biblesoft’s New Exhaustive Strong’s Numbers and Concordance with Expanded Greek-Hebrew Dictionary. Copyright Â© 1994, 2003, 2006 Biblesoft, Inc. and International Bible Translators, Inc.)

The Greek word for Christ, Strong’s word 5547, Christos, means Christ or Messiah.

So, the term Antichrist can mean Opposite of Christ or Instead of Christ.

After Emperor Constantine issued his Edict Against Heretics in 331 A.D., it began to become clearer to those associated with the true Church that perhaps a church proclaiming Christianity and tied into the Roman Empire should be identified with antichrist.

Notice what the Roman Catholic Cardinal Newman wrote about it in the 19th century:

Now, one of the first questions which it is natural to ask on entering upon the subject is, whereas the Pope is said to be Antichrist, sometimes from the fourth, sometimes from the seventh century, when was he first detected and denounced, and by whom?
On this point Dr. Todd supplies us with much information, from which it appears that the belief that the Pope was Antichrist was the conclusion gradually formed and matured out of the belief that the Church of Rome was Babylon, by three heretical bodies, between the eleventh and sixteenth centuries, in consequence of their being submitted to persecution for their opinions:
“In the middle of the eleventh century, numerous emigrants from Thrace and the East had established themselves in the north of Italy, and especially in the neighbourhood of Milan; and some, despising a fixed habitation, or unable to obtain one, itinerated throughout various parts of France and Germany. The doctrines of these sects exhibit various shades of extravagance and error, and appear to have had a close affinity with the Oriental Manichees or Paulicians, from whom they are historically descended…they despised all external religion, ridiculed the office and powers of the priesthood, the efficacy of the Sacraments, and especially the use of baptism.”—Pp. 28-30.
These were the Albigenses, the first of the three independent families of heresy above mentioned…It would appear from these that the Albigenses founded their opposition to the Church on a Manichæan principle, viz., that, as there was an evil deity, and he the author of the visible world, so was he author also of the visible Church, which in consequence was “the devil’s basilica and synagogue of Satan,” and, in the language of the Apocalypse, “the mother of fornications.” (Newman JH. The Protestant Idea of Antichrist. [British Critic, Oct. 1840]. Newman Reader — Works of John Henry Newman. Copyright © 2004 by The National Institute for Newman Studies. http://www.newmanreader.org/works/essays/volume2/antichrist1.html viewed 12/03/07).

What the Cardinal seems to be teaching is that beginning in the fourth-seventh centuries one or two groups apparently began to feel that the Pontifex Maximus was an antichrist and that one who calls himself Pontifex Maximus may be the final antichrist. The Roman bishops did not refer to themselves by the pagan title of Pontifex Maximus (literally meaning the “greatest bridge-builder” between mortals and the gods) until the late 4th century.

It is likely no coincidence that after bishops of Rome took the title Pontifex Maximus in the late 4th century and “vicar of Christ” in the 5th century that more started to believe that the Bishop of Rome represented the final Antichrist.

Many Greco-Roman Catholic prophecies suggest that it will be a pope, or more precisely an antipope, that will arise and perhaps be the final Antichrist:

Oba Prophecy. “It will come when the Church authorities issue directives to support a new cult, when priests are forbidden to celebrate in any other, when the highest positions in the Church are given to perjurers and hypocrites, when only the renegades are admitted to occupy those positions (Dupont Yves. Catholic Prophecy: The Coming Chastisement. TAN Books, Rockford (IL), p. 115).
Anna-Katarina Emmerick (19th century). “I saw again a new and odd-looking Church which they were trying to build. There was nothing holy about it…(Dupont, p. 116).
Yves Dupont (writer interpreting A. Emmerick), “They wanted to make a new Church, a Church of human manufacture, but God had other designs…An anti-pope shall be set up in Rome” (Dupont, p. 116).
The Prophecy of Premol (5th century) “…And I see the King of Rome and his Cross and his tiara, shaking the dust off of his shoes, and hastening his flight to other shores. Thy Church, O Lord, is torn apart by her own children. One camp is faithful to the fleeing Pontiff, the other is subject to the new government of Rome which has broken the tiara. But Almighty God will, in His mercy, put an end to this confusion and a new age will begin. Then, said the Spirit, this is the beginning of the End of Time.”
Comment: From this prophecy, it is clear that the true Church will be faithful to the Pope in exile; whereas the new Pope in Rome will be, in fact, an anti-pope…a large number of Catholics will be misled into accepting the leadership of the anti-pope. (Dupont, pp. 72-73). {Note the comment is from Dupont personally}.
Jeanne le Royer (d. 1978) I see that when the Second Coming of Christ approaches a bad priest will do much harm to the Church (Culligan, E. The Last World War and the End of Time. The book was blessed by Pope Paul VI, 1966. TAN Books, Rockford (IL), p. 128).
Yves Dupont {reader and collector of Catholic prophecies} “prophecies are quite explicit about the election of an anti-pope…Many prophecies predict an anti-pope and a schism” (Dupont, pp. 34,60-61).
Catholic priest and writer R. Gerald Culleton: “A schism of short duration is destined to break out…An antipope, of German origin, is to be set up, and finally Rome itself will be destroyed” (Culleton, R. Gerald. The Prophets and Our Times. Nihil Obstat: L. Arvin. Imprimatur: Philip G. Scher, Bishop of Monterey-Fresno, November 15, 1941. Reprint 1974, TAN Books, Rockford (IL), p. 42).
Cardinal John Henry Newman (died 1890): The defenders of the Papal-Antichrist theory… cite St. Bernard as identifying the Beast of the Apocalypse with the Pope, though St. Bernard speaks in the passage of the Antipope; they appeal to the Abbot Joachim as believing that Antichrist will be elevated to the Apostolic See, while the Abbot really believes that Antichrist will overthrow the Pope and usurp his See … Antichrist must have some similarity to the Pope… (Cited in Mass A.J. Antichrist. The Catholic Encyclopedia, Volume I. Copyright © 1907 by Robert Appleton Company. Online Edition Copyright © 2003 by K. Knight. Nihil Obstat, March 1, 1907. Remy Lafort, S.T.D., Censor. Imprimatur. +John Cardinal Farley, Archbishop of New York).
Priest S. Berry (20th Century): Then the earth whence comes the second beast is a symbol of the Gentile nations in revolt against the Church. The two horns denote a twofold authority — spiritual and temporal….the prophet will probably set himself up in Rome as a sort of anti-pope…(From Interpretation of the Apocalypse, quoted in Culleton R. Gerald. The Reign of Antichrist, Reprint TAN Books, Rockford, IL, 1974, 199-200).

Frederick William Faber (died 1863)…Antichrist…Many believe in a demonical incarnation–this will not be so–but he will be utterly possessed…His doctrine as apparent contradiction of no religion, yet a new religion…He has an attending pontiff, so separating regal and prophetic office (Connor, Edward. Prophecy for Today. Imprimatur + A.J. Willinger, Bishop of Monterey-Fresno; Reprint: Tan Books and Publishers, Rockford (IL), 1984, p. 87).
Blessed Joachim (died 1202): “Towards the end of the world Antichrist will overthrow the Pope and usurp his See” (Connor, p. 76).
Merlin (7th century) “There will come a German Anti-Pope. Italy and Germany will be sorely troubled. A French King will restore the true Pope” (Culleton, p. 132).
St. Francis of Assisi (d. 1226) “There will be an uncanonically elected pope who will cause a great Schism, there will be divers thoughts preached which will cause many, even those in the different orders, to doubt, yea even agree with those heretics which will cause My order to divide, then will there be such universal dissentions and persecutions that if these days were not shortened even the elect would be lost” (Culleton, p. 130).
Catholic writer and priest P. Huchedé (19th century): “…the false prophet…will not be a king, nor a general of an army, but a clever apostate, fallen from episcopal dignity. From being an apostle of the Gospel he will become the first preacher of the false messiah…” (Huchedé, P. Translated by JBD. History of Antichrist. Imprimatur Edward Charles Fabre, Bishop of Montreal. English edition 1884, Reprint 1976. TAN Books, Rockford (IL), p. 24).
St. Gregory the Great, Pope (d. 604): In those days, near the end … an army of priest and two-thirds of the Christians will join the Schism (Culleton, R. Gerald. The Reign of Antichrist, p. 122)
Priest Herman Kramer This false prophet possibly at the behest of Antichrist usurps the papal supremacy…His assumed spiritual authority and supremacy over the Church would make him resemble the Bishop of Rome…He would be Pontifex Maximus, a title of pagan emperors, having spiritual and temporal authority. Assuming authority without having it makes him the False Prophet…Though he poses as a lamb, his doctrines betray him (Kramer H.B. L. The Book of Destiny. Nihil Obstat: J.S. Considine, O.P., Censor Deputatus. Imprimatur: +Joseph M. Mueller, Bishop of Sioux City, Iowa, January 26, 1956. Reprint TAN Books, Rockford (IL), p. 319).

Note: I want to make it clear that consistent with biblical and Greco-Roman Catholic prophecies, I believe that the final Antichrist will pretend to be a Roman Catholic and betray that church (cf. Revelation 17:15-18).

That being said, I do not believe that terms such as reverend (cf. Psalm 111:9, KJV), pontifex maximus (an old pagan title meaning bridge builder), or “vicar of Christ” should be used of leaders who claim to be Christian.
