If you really read the Jeremiah passage carefully, in Old Testament context, and to line up with the rest of the Bible, you will find that "The Great Speckled Bird" really represents the Children of Israel, NOT "the great Church of God." It's ridiculous when people call their group "Israel" when the Bible is, in fact, literally talking about ISRAEL when it is talking about Israel. It should be obvious now, with the reestablishing of the nation of Israel, that the biblical concept of this nation is not obsolete and there is no need that any "church" replaces Israel. Israel and the Church are two entirely different concepts.
