This has been brought up here recently. Junia is spoken of in Romans 16:7 as an "apostle". Just a couple of things here: 1. "Apostle" simply means "sent one". A missionary could be called an "apostle" by strict definition. It does not have to be an office. 2. The Lord hand picked twelve "apostles" who had certain authority. There are only twelve of these. They are all now dead. Now, on what grounds would you say that Junia is a man or woman?
