They often sponsor dinners or shows or outings for the school. In freshman year we have what is called a Personal Development course for non-catholics instead of Religion. Often it is similar, but more emphasis is placed on the traditions of the students. This was begun by John Browning way back in the 70's. It seems fine.
Different moderators have exchange programs with German, Italian, and Spanish students.
Our prayer service included readings from Hebrew Scriptures, Koran, etc. Students of that religious tradition then reflected on that and what their religion means to them. This has turned out to be very positive. We also have a multi-cultural club that tries to help others appreciate the religious traditions. We had a fine forum last year chaired by David Patel.
