56% of the Supreme Court is Roman Catholic - http://www.adherents.com/adh_sc.html

“And upon her forehead a name written, Mystery, Babylon the Great”—She is a mystery, and yet this mystery is written on her forehead for everyone to read. This implies that whoever has an eye can perceive the meaning of this mystery.

God recognized Jerusalem as the center of worship (religious) as well as the center of earthly dominion (political). The error of the Roman Church is to presume that God has established her in lieu of Jerusalem, thus making herself both a religious and political center. What Jerusalem is rightfully to be in the millennial kingdom is what the Roman Church has today already assumed.

“The mother of the harlots”—Being herself the great harlot, all that come out of this woman are harlots. These are the state churches, since their institutional systems are similar to that of Rome. Any church group that is united with the world is a small harlot. (For example, membership is not based on regeneration, but is granted to any who pledge to give support financially; also, the qualification for taking communion or the Lord’s Supper is membership instead of salvation; and so forth).

“Mother . . . of the abominations of the earth”—Abominations in Old Testament times always pointed to idols (see Deut. 7.25,26). The Roman Church is known for her idol-worshiping. She worships Mary, angels, apostles, saints, and so forth. Her split with Constantinople was over this matter of her idol-worshiping.

Rome was not only politically a city, it was also a center of religion. In the city of Rome were to be found many Christians, yet Rome hated Christians the most. Not until the fourth century after Christ did Constantine the Great accept Christianity and encourage his people to do the same. With the result that Christianity became the official religion of Rome. At the same time, though, the center of politics shifted from Rome to Constantinople. Rome itself became subject to the rule of Constantinople and remained that way until the sixth century. At the time of Leo a general council was held at Constantinople wherein idol-worship was condemned as heretical and illegal. Rome opposed this, and she broke with Constantinople. Thus were formed the Eastern Roman Church (the Greek Orthodox Church) and the Western Roman Church (the Roman Catholic Church). The influence of the Eastern Roman Church began to wane, but that of the Western Roman Church increased steadily. A great number of Christians suffered death at the hands of the Roman Catholic Church.

According to Revelation 17 and 18 the Roman Catholic Church will experience tremendous growth in the future, far exceeding that of the past. Her influence will be enormous. But when Antichrist shall arise and set up his image as an object of worship, he with his ten subordinate kings shall destroy the Roman Church. Nevertheless, with the passing of Rome religious, Rome political will still continue. She will make the Mediterranean Sea a center of her influence. Three and a half years later, God will destroy Rome political.

The Catholic Church has major problems and God promises she will be destroyed when He returns. Why does God call this woman a harlot? (Revelation 17). Because she communicates and commingles with the world. She has so broadened the communion of the saints as to hold inter course with the world. What she gains is worldly pleasure and earthly glory. She has become savorless salt. A harlot is one who commits fornication without the due process of marriage. An adulteress is a woman who commits fornication after being married. God therefore calls her a harlot, since a harlot is a woman who commits fornication before marriage; thus signifying that God has never recognized the relationship between the Roman Church and Christ. Like a harlot, the Roman Church has not kept her virginity for Christ.

This woman is called a “great harlot”: Had the Roman Catholic Church observed Matthew 5-7, she could not be great—she could only develop into a “little flock” (Luke 12.32). Her testimony would simply be that the world is rebellious and that Christ shall come again to judge it. Her being “great” is exactly what the Lord predicted in Matthew 13.32. In this connection we need to read Genesis 1 which states that “the earth brought forth grass, herbs yielding seed after their kind, and trees bearing fruit, wherein is the seed thereof, after their kind” (v.12). Yet Matthew 13 records the Lord Jesus as saying this: “When it is grown, it is greater than the herbs, and becometh a tree” (v.32). Hence the greatness here described in Revelation is the greatness of a harlot. Please observe that the Romish pope is greater than an emperor. An emperor can only control a man’s body, but a pope can control a man’s soul, yes, even that of the emperor’s. Now such a situation is not at all normal for the church on earth.

“With whom the kings of the earth committed fornication” (Rev. 17.2)—By way of explanation please consider the following:
(1) In order to please the kings of the earth, the Roman Church was willing to baptize them as long as they wished to be baptized. Thus, she auctioned away the principles of Christ and the word of God.

(2) She made the church co-extensive with the state. Christianity became the state religion of Rome. Anyone who was born a Roman could be a Christian. Normally the church was smaller than the state, but now she became equally as big.

(3) The Church joined to herself the political powers of kings and rulers. The foremost sin of fornication she can commit is to force Christianity on the people by means of the powers of kings and emperors. This was done not only by Rome but also by many other nations. The result was to make merely nominal Christians out of people.

To commit fornication with the kings of the earth is said to be, interpretively speaking, the Roman Church’s direct relationship with them. But the verse, “and they that dwell in the earth were made drunken with the wine of her fornication”, speaks of her indirect relationship with the people on earth. Wine here signifies heresies. The Romish Church has caused people on earth to lose their self-determination and to become foolish through heretical doctrines. On the one hand she has taught that by giving a little money and by making confession to a priest a person’s sin may be forgiven, but on the other hand she has failed to instruct people how they ought to live a holy life. She allows them to indulge in worldly pleasures. Indeed, this wine of her fornication has made the whole world drunk. It is quite true that without religion no one could live on earth. For this reason, the Roman Church is most palatable to the taste of the world. She disregards spiritual reality on the one hand, yet on the other uses all sorts of religious rituals to create emotional comforts as well as glowing expectation within the hearts of the people.

So has been the Church of Rome, and so shall she be revived in the future. Furthermore, once a Roman Catholic, one dies a Roman Catholic. Several big denominations in the United States had no increase during one year, whereas the Roman Catholics added several millions to their record.
