Christianity has been and always will be a gentile religion.
Jesus' statement to "make disciples of all nations" comes from Matthew 28:19, a key part of the Great Commission. He commanded his followers to go and teach people about him, baptizing them and helping them to live according to his teachings. The term "nations" in this context refers to ethno-linguistic groups or people groups, rather than modern political states.
