Yes, ONE chapter out of 260ish chapters in the New Testament. So relatively speaking, it IS an excerpt, considering the overwhelming majority of the New Testament which strongly advocates for replacement theology/supersessionism. You can close your eyes and flip to almost anywhere in the NT and land on a passage that either directly or indirectly points to Jesus as THE Way, faith over works, the first shall be last (and vice versa), and so on. For most of the history of Christianity, Catholicism, Orthodox and early Protestantism all preached supersessionism. It wasn't until the fraudster/criminal Scofield and his cohorts in the late 19th century that dispensationalism was invented along with Christian Zionism and Jewish exceptionalism.
Conveniently this was the same time that Britain began eyeing Palestine and the modern Zionist movement began. Rothschild and other Jews began identifying "philanthropic" opportunities to move Jews there as a new Western colony in a critical geostrategic zone: the nexus of Europe, Africa, and Asia. Plus Germany and Russia was challenging UK primacy in the area by making inroads through the Balkans to the coveted Middle East as oil began to replace coal. So the new Evangelical movements in Britain and America, along with their Christian Zionist obsession, dovetailed nicely with Anglo-American foreign policy priorities leading up to WW1: break up and "balkanize" all the axial powers (e.g. the German, Austro-Hungarian, and Ottoman Empires) to protect UK, French, and later US access to precious oil, pipelines, and trade routes. Ever since WW1, the objective of the West, as the dominant maritime power (and later air power), has been to keep strategic land powers balkanized and fractious with their neighbors, lest they unify and resist intervention by outside and remote powers.
This quick summary brings us back to why we're discussing this in a thread about Israel vs Iran. Israel, or you might say the West via Israel, or you might say Israel via the West (it's hard to know who is doing the wagging), has relied on this theological innovation to keep a critical number of Westerners supportive or at least tolerant of what would otherwise be an unpopular war in remote lands with nothing but increased debt, taxes, and security threats offered in return to Western taxpayers. So much for blessing those who bless Israel. Endless wars continue to destroy our way of life, our institutions, the nuclear family, the birth rates, etc. Let me know when we can expect to receive our blessings for being the largest benefactor to Israel in history. I'm guessing we'll be waiting for as long as we've been waiting for the messiah to return.
