because the church was the gateway to heaven, and Ben isn't allowed in heaven.
and why was he not allowed to go to heaven?
well i'm not exactly sure. My theory is that he killed Jacob, or he just killed a lot of people in general and he was a jerk. or maybe he has another purpose in life, probably not though
Because he still had things unresolved and things he needed to forgive himself for. He didn't feel ready to 'let go' and move on.

He was only at the church to see everyone off, not to go with them
I think Ben didn't want to go into the church because he still wanted to linger in a world where he could continue to play father figure to Alex. Similarly, Eloise Hawking/Widmore didn't want to "rock the boat" if it meant losing time with her son Daniel. Presumably, once Alex and Daniel are "ready", Ben and Eloise will move on with them.
I'll accept that. Its an interesting way of seeing the end of one's life.
Ben seemed to have a choice about entering or not - so he was either still making ammends / apologies or waiting for Alex or both.
