Answer to: "...Does anyone here know what type of Christian churches support Israel..."
Yes.
Almost all of the non-mainstream churches (often referred to as the "low" churches by Christians) do support the Jewish claim to all the land of Israel.
Pentecostals, Assemblies of G-d, the large number of "Evangelicals" are the most prominent among them.
Essentially, these are Christian congregations which literally believe the Jewish Scriptures and the Prophecies as they are written.
They are centered on faith; as opposed to viewing their church as a business corporation which must adjust to modern secular pressures.
Today, the Episcopals, Catholics, Methodists, Presbyterians, Lutherans, and some Baptists, have been quite literally bought and sold by the Saudis, the feminists,and the homosexuals.
Make no mistake about it; the Conservative as well as Reform branches of Judaism would have long ago accepted Saudi money, if only the Arabs would have given them any.
This being the case, all but the true Orthodox Sects of Judaism have already announced their "sell-out" to first the feminist agenda, and just recently joined the homosexual agenda.
As a general rule:
"If the secular Jews, the media, and the so-called "liberals" knock them, ridicule them, and fear them; then more likely than not they should be considered as current or potential allies of the Jewish people."
