I'm saying there is no difference. If you are a Christian, regardless of denominational ties; ie. baptist, methodist, etc., if you consider yourself a Christian, you should be Apostolic. Apostolic does not mean
Acts 2:38: the early Apostles built on Jesus Christ and Him crucified.
The term in and of itself is misleading. To say you are Apostolic just because you believe God requires three steps to salvation is a fallacy.
The disciples merely preached Jesus. That's all. They had no agenda, no personal ambitions, they gave their lives for Jesus and His gospel.
I know many who consider themselves Apostolic, (because of their standards) but completely ignore Christian ethics. They gossip, lie, cheat, backbite, hate their brothers, consider everybody else lost, consumed by jealousy, bitterness, etc.
Either you are a Christian or you are not saved.
