New Pastor at Church

I was attending a church service in a church that was unfamiliar to me.  The seats were arraigned so that the made circles and each circle got smaller and higher leading the top where the pastor sat.  The pastor said he was going to step down because of political reasons within the church and announced me as the new pastor.  I was quite surprised but went up and gave a small talk.  The pastor left with a bunch of men to discuss the political problems and they told me I could not attend the meeting.  I was a little upset about it but was more upset that I would have to give a sermon each week and lead the prayers.
