Church and mission 10/14-The hyphenated teacher

All leaders are usually teachers in some capacity or another. It is in the job description to define reality and to train others. In the five fold ministry passage(Ephesians 4:11-12) there has been debate over whether there were just plain old teachers in the early church. I know some people nowadays who can teach and only teach and I would not say that they were leaders necessarily. It seems to me that in order to lead you would have to be connected to the body in some other people oriented way other than teaching. What do you think?
