When the LORD first spoke through Hosea, the LORD said to Hosea, “Go, take to yourself a wife of harlotry and have children of harlotry, for the land commits great harlotry by forsaking the LORD.” So he went and took Gomer the daughter of Diblaim, and she conceived and bore him a son. And the LORD said to him, “Call his name Jezreel; for yet a little while, and I will punish the house of Jehu for the blood of Jezreel, and I will put an end to the kingdom of the house of Israel. And on that day, I will break the bow of Israel in the valley of Jezreel.” She conceived again and bore a daughter. And the LORD said to him, “Call her name Not pitied, for I will no more have pity on the house of Israel, to forgive them at all. … When she had weaned Not pitied, she conceived and bore a son. And the LORD said, “Call his name Not my people, for you are not my people and I am not your God.” — Hosea the Prophet
But when he saw many of the Pharisees and Sadducees coming for baptism, he said to them, “You brood of vipers! Who warned you to flee from the wrath to come? Bear fruit that befits repentance, and do not presume to say to yourselves, `We have Abraham as our father’; for I tell you, God is able from these stones to raise up children to Abraham. Even now the axe is laid to the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire. — John the Baptist
Biblically speaking, it isn’t semen and egg which make one a child of God, a citizen of the kingdom of heaven; it is faith. Hence semen and egg grant no particular privilege, even according to the Prophets of the Old Testament. To say such a truth isn’t antisemitism, it’s sound theology.
So for that reason all claims that Israel, a modern secular state whose inhabitants, by virtue of connection to semen and egg traced back to an ancestor millenia ago, has a special claim on God or a special relationship to God which others do not is both theologically bankrupt and ideologically driven.
Christian Zionism is a heresy because it misrepresents divine revelation. Christian Zionists are heretics not because they are bad people, but because they contort the truth of revelation to their own political (and it is nothing other than a political) agenda.
Their last refuge is the slur of antisemitism. When biblical exegesis and theological understanding abandon them (as they must), their only recourse is a historically villainous slander which, as a straw man, they hope will distract attention away from the truth of their theological ineptitude and incompetent exegesis. But what they don’t even have the good sense to recognize is that the biblical authors lambasted Israel’s unbelievers more soundly than any modern antisemite could imagine.
So, when you stand on the side of equality and fairness for all peoples of the Middle East (and everywhere) and a Christian Zionist assaults you with the slander of antisemitism, calmly open the Bible and point them to Hosea and John the Baptist and see what they say next. It will, I promise you, be amusing, inappropriate, and a complete evasion of the biblical witness.
