Christ Has But One Bride
But I want you to understand that the head of every man is Christ, the head of a wife is her husband, and the head of Christ is God. Every man who prays or prophesies with his head covered dishonors his head, but every wife who prays or prophesies with her head uncovered dishonors her head, since it is the same as if her head were shaven. For if a wife will not cover her head, then she should cut her hair short. But since it is disgraceful for a wife to cut off her hair or shave her head, let her cover her head. For a man ought not to cover his head, since he is the image and glory of God, but woman is the glory of man. For man was not made from woman, but woman from man.
— 1 Corinthians 11:3–8 (ESV)
Christ is the Head of the Church. Marriage and the relationship of Christ to His Church are typologically linked. Those who serve in positions of authority in the Church must be husbands of one wife, for they are typological representations of Christ, Who is Head of one Church. As Christ has but one mystical, spiritual body — His Church —, so the man who represents Christ in His Church must have one body — his wife — of which he is the head.
Pastors and overseers may not practice polygyny, for Christ is true to His one bride. Any doctrine that would make of Christ a spiritual polygynist is false on its face. Any dogma that would attribute to Christ a mystical body other than His Church is blasphemous. Zionism attributes to Christ a second body, for it contends that He is the (spiritual) head of ethnic Israel.
Christ is not the head of ethnic Israel. For a time, in the Old Testament, God, more or less, directly ruled ethnic Israel. Before they were given a king, God Himself ruled Old Testament Israel through His prophets (e.g., Moses) and His judges (e.g., Samson). This, along with the subsequent reign of (certain of) the Old Testament kings, was a temporal and typological fulfillment of God's promises to Abraham — promises that have their ultimate fulfillment in Christ, in the Church, and in the Eschaton. But does this mean that ethnic Israel was a mystical body of Christ, was the Church? No.
The Church is the congregation of saints, in which the Gospel is rightly taught and the Sacraments are rightly administered. Now, in this life, hypocrites and wicked men are mingled with the visible Church and outwardly may appear to be in fellowship with the saints, but the Church is not only the fellowship of outward objects and rites, but is truly a fellowship of faith and of the Holy Ghost in the hearts of saints. The mystical body of Christ, that is to say His Church, is comprised of the Elect from every language, tribe, and nation, from Adam and righteous Abel up to the last man to stand before the Throne with nothing but the blood of Christ to enter as his plea. As the wicked, indeed, are not a holy Church, so the wicked are not properly part of Christ's body.
Ethnic Israel was — and is — a wicked nation that rejected — and still rejects — God. God was true to His promises that the Messiah would be born of man (Adam) from the line of Shem through Abraham and his son David, but that was all fulfilled two thousand years ago, and God made clear His displeasure and the current standing of ethnic Israel in AD 70 when he committed them, their cities, and the Temple to utter destruction at Roman hands.
The true Church, the spiritual Israel, the Israel of God is comprised of the Elect — and no others. Those who will die impenitent and unbelieving are not part of Christ, and so are not part of the Church — the true Israel. Ethnic Israel declared its allegiance in Pilate's courtyard:
So when Pilate saw that he was gaining nothing, but rather that a riot was beginning, he took water and washed his hands before the crowd, saying, “I am innocent of this man’s blood; see to it yourselves.” And all the people answered, “His blood be on us and on our children!” Then he released for them Barabbas, and having scourged Jesus, delivered him to be crucified.
— Matthew 27:24–26
God has granted them their desire.
Christians are not Zionists and Zionists are not Christian. Geopolitical Israel is an aberration and has no more to do with Scripture or prophecy than Madagascar or Uganda, and ethnic Israel is willfully apostate, pagan, and impenitent. Christians are explicitly told not to associate with such persons. Those who willfully associate themselves with Zionism or Zionists are in danger of rejecting God in favor of false doctrine, false dogma, and wickedness.
God is perfect light — in Him there is no darkness at all. So, too, in the body of Christ there are only spotless saints, who have been washed clean in the blood of the Lamb. Yes, in this life, we are yet tainted by sin that clings to our fallen flesh and our fallen nature, we feebly struggle against temptation and sin, but the saints in glory shine and we will one day — soon — join them. Ultimately, in the new Heavens and the new Earth, there will be no sinners, for only those who are in Christ will remain. Those who are apostate, impenitent will never see the new Heavens and the new Earth, for they are not in Christ. The Zionist is not in Christ, for he has chosen another god. A tree is known by its fruits, and ethnic Israel does not produce good fruit.
Christ is the typological husband of one typological wife — His Church. Ethnic Israel is a street harlot who pretends to the place of faithful wife — she is a liar, a murderess, and a whore. Zionism is the election of the harlot over the faithful wife; those who follow the harlot will share in her end, where there will be weeping and gnashing of teeth.
Christians are not Zionists.
Christians are anti-Zionist.
