Your feed is at http://imergentchurch.com/feed/podcast/
The latest episode in it is called 'The hour has come' and this appears in the Store and when subscribing, so everything is fully up to date.
You are in the habit of posting a number of episodes on the same day, in some cases only minutes apart. This is liable to lead to some subscribers missing automatically downloading an episode if more than one has appeared between the times iTunes checks the feed. (They will see the episodes, but will have to manually download any which haven't been automatically downloaded.)
When you have a query please always post the feed URL: and it's better to start your own thread rather than tack onto someone else's - as you can see, yours turns out to be an unrelated question; and doing so can cause interleaved answers in a thread which can get rather messy and confusing, particularly for the person who started it.
Edit: In fact I now see that you also started a new thread. Please don't post a question in more than one place. The result of this is that I've taken the time to research and answer your question only to find out that Robert Walch has already done that and answered it. I don't appreciate this.
