I personally find myself wondering why one has an interfaith gathering entitled as such in the first place. If there is a goal for such a meeting it seems like that should be how you frame it. By framing a conversation as religious perspective you are going to get religious statements which (at least from my perspective) are dogmatic and come from a point of view that there is one truth.

If you approach a discussion as "we are all parties who are interested in this topic" and allow your beliefs to inform your opinions on how to address the topic you might be able to skirt the problem of dogma, but as long as your opinions are defined by a belief that you are certain is "truth" it is hard to see how compromise could be reached on areas of disagreement. Of course if your purpose is to just find areas of common ground and not persuade anyone to your point of view than you may also be able to have productive discourse.
