This week's heresy gets into some dispensationalism/Messianic Jewish ideas.
Anglo-Israelism (also known as British Israelism) is a 19th-21st century protestant heresy that forms the basis of the Christian Identity Movement and purports that the English (in specific) and white people (in general) are descendants of the Ten Lost Tribes of Israel. They subscribe to something called the “Two House Theology”, meaning all Jews are Israelites, but not all Israelites are Jews. They believe that the Jews descended only from the tribes of Judah and Benjamin. There is documentation to show that even the British Monarchy believes itself descendants of King David. While the Catholic Church has no official stance on this heresy, many sects and denominations have rejected Anglo-Israelism.
