Perhaps it is proof of the supernatural truth of Christianity that heresy tends to snowball into things that have vast consequences.
I believe in God the Father Almighty,Maker of heaven and earth:And in Jesus Christ his only Son our Lord, Who was conceived by the Holy Ghost, born of the Virgin Mary, suffered under Pontius Pilate,was crucified, dead, and buried: He descended into hell; the third day he rose again from the dead; He ascended into heaven, and sitteth on the right hand of God the Father Almighty; from thence he shall come to judge the quick and the dead.I believe in the Holy Ghost; the holy catholic Church; the Communion of Saints; the Forgiveness of sins; the Resurrection of the body, and the Life everlasting. Amen.
Look at what happened when people began denying the one communion of saints. Finding that the Church was not named by name in the Hebrew Bible, some folks imagined that the Jews might have some kind of eschatological fate separate from the Church.
This break in the unity of the communion of saints led to further breaches in unity. No more single Second Coming; the Church gets a separate second coming and the Jews get a third coming. No more single Last Judgment; they too come in a series of multiple judgments. The Bible is shattered, treated like a jigsaw puzzle that believers must piece together.
Eventually this heresy led to a floridly psychotic interpretation of history. Omens of the End Times were seen in current events. The foundation of the Jewish state in Palestine was invested with cosmic significance. Because we have been blessed through Israel, the heretics transfer this blessing to the current Israeli government and all its oppressive works, which, though not the worst that's ever been, are nothing we should smile on. Because war is found in prophecy, the heretics turned their back on Jesus blessing the peacemakers. Instead, they teach us to look forward to wars, especially Middle Eastern wars, for they are omens that Christ's return is imminent. Peace is the language of the Antichrist, according to the heretics. The Antichrist is a single person, a satanic Messiah, and he might be the talking head on the TV, or the King of Spain, or the prime minister of Vanuatu, or your next door neighbor.
When Jesus does return, these people will appear before Him and say, "Look at what we brought you! War, tyranny, and paranoia! Aren't You proud of us?"
Astounding that such a small matter of apparently arcane theology started a snowball rolling that led to the construction of an entire belief system that Christians ought to regard with disgust and dismay and that it has deceived many believers.
