I was heavily involved with a religious group during college (a chapter of a mainstream organization, nothing extremist), ending as president. This involved a lot of planning, organizing and running events, figuring out how to get members more involved, making and requesting budgets, etc. -- general "leadership" stuff. It probably took up 75% of my extracurricular activities during college, and I learned a lot about running a long-term group.
When I graduated I was proud to have it on my resume, religious implications and all. However, I have since had a change of faith and would feel awkward if someone assumed I still held those beliefs.
The problem is that I do not have any other significant leadership experience, just a couple of smaller things where I was not the main person in charge - not nearly the same extent or commitment. So I feel that keeping it on my resume would help me be seen as a potential leader in the workplace, which is my goal. (I currently have trouble with that because of my personality type and lack of experiences to discuss, so people just assume I am not the "leader" type.)
Is is possible to write this experience into a "generic" listing for my resume, and avoid/gloss over the personal backstory? (How?) Or is it best to just leave it off altogether and deal with the empty spot in my resume some other way?
