As we don’t discuss religion or politics in lodge I don’t see it being valuable to attend church or parlent for that matter with my brothers from a faith perspective.
That said having speakers of faith visit lodge would be a different thing, becoming educated on the religions of the world from an academic standpoint would be fantastic.
Me, I've learned a lot about Hinduism and Islam from my friends and Brothers - in a much better format - over dinner, coffee, beer, wine and phone..
I've attended different Churches for Weddings, Funerals and Christenings - community events in support of my close Brothers - never been to a GL organised Church or Synagogue visit - never felt the need - but if a close Brother passes, or one of his family does, I'd been in any place of worship he wanted me to be to support him.
I would oppose a discussion of religion in lodge - unless academic and comparative, but even then, I still don't think Lodge is the right place to do it - I can tell you I've sat through lectures on history where politics and religion have come up and I've had to practice that wonderful masonic virtue - silence. The best example I can think of is a WASP (not using that acronym in a derogative way - but as short hand) extolling the virtues of Oliver Cromwell - he went on and on and on - Irish Catholics have a very different view of the man who is seen as overseeing massacres and destruction... while on another level we simply had a military dictator and religious zealot - but we need to let go of the emotion in such history, hanging onto it is a great way to move away from a state of peace.
