State: No Religion, False Religion, Christian
A State may either have 1) no religion, be that of a 2) false religion, or be 3) Christian. It would seem that Christians would advocate for the State to be Christian. (Note that there may be a further disagreement about which Christian religion is true, versus false Christian claimants: Catholicism versus Orthodoxy versus Protestantism, etc.)
Abortion Example
Consider the example of abortion: if there is 1) no religion, the people may be "free" to have abortions. Christians would not support this. Likewise, a 2) false religion might assert a right to abortions. Hence a Christian would not support a false religion in doing this. Therefore there would be a tendency of Christians to want the State to reflect Christian values, or to be 3) Christian.
Israel: No Religion or Christian?
There are some who identify as Christian who advocate for there to be 1) no state religion. Assume for the sake of argument that this is an acceptable position to take: then, they would advocate for Israel to not be a religiously Jewish state. If they 3) advocate for Israel to be Christian, then they also wouldn't advocate for Israel to be a religiously Jewish state, and it would seem irrational for a Christian to advocate for a state to be 2) religiously Jewish (considered to be a false religion from the Christian perspective) rather than 3) Christian.
Hence those who identify as Christian would only advocate for Israel to be 3) Christian, or 1) to have no religion; in neither case would they advocate for 2) Israel to be religiously Jewish (which is considered to be a false religion, from the Christian viewpont).
Conclusion
Therefore, is it not impossible for Christians to be Zionists, or to want the state of Israel to be religiously Jewish?
