Recently spotted that a local church had arranged for some Buddhist monks to visit, and they subsequently performed a ritual inside the church building, which they then went out from and offered to people's homes. It also happened a couple of years ago when it ruffled a few feathers.
I know I wouldn't have done the same in their vicar's shoes, but I have been trying to work out why not. Here's a bit of thinking aloud as a work in progress. I'd be really interested to see what other people think.
There is the obvious inconvenience of getting hassle from the "turn or burn" version of Christianity which would see other faith activity as potentially if not actually evil. However, I suspect I am going to upset people from that school of thought anyway at some point, so that's not a good enough reason in itself.
The more interesting questions are about the nature of sacred space, and also the integrity of Christian identity. here on campus, the policy is quite clear that the chapel is for Christian worship and is also used for music and arts performances which are appropriate for the context. Most members of other faith communities wouldn't want to worship in chapel anyway, and a multifaith prayer room is available, or other rooms can be used if more space is required.
This particular Buddhist group clearly didn't have any issue with using a church for their ritual. However, I do have a problem with a Christian building being used to effectively propagate another faith viewpoint. (The monks took sand from their ritual out to places in the community) That seems to be moving from hospitality to endorsement, which is different. The problem is that once you start suggesting boundaries, it's very easy to seem narrow-minded.
I suspect the issue behind this is the methodology for relating between faiths. Is it multifaith - trying to find common denominators and rituals and practise which are a compromise, or is it inter-faith, where no-one has to compromise their own identity, but learn to listen and have a dialogue with others who are different. Can't quite join up the conceptual dots, but I think that's it.
