Critics of Christian Zionism usually dismiss it for one or more of three reasons: (1) They say it makes mincemeat of the New Testament, where (it is alleged) the Old Testament focus on a particular land is replaced by the vision of a whole world; (2) They think it is the exclusive concern of premillennial dispensationalists, whose theology supposedly uses Jews to advance its own role in presumptuous schedules of End Time events; (3) It is said to be more political than theological, attached to right-wing American and Israeli political parties that wrongly identify the current Israeli state with the eschaton.
But there are now emerging fresh approaches to these three problems.
