One of the strongest-sounding arguments from replacement (or “fulfillment”) theology says the church has always been Israel—so how can the ekklesia replace the ekklesia? Dr. Michael Brown walks through Septuagint examples where kahal becomes ekklesia, then shows why Acts 7:38 doesn’t settle the debate. You’ll see how New Testament usage specializes the word for followers of Jesus—and why saying the ekklesia has always been the ekklesia is still replacement theology by another name.
