year. TWU's president at the time, Robert Kuhn (2014–19), said in a statement that the change was so that the university could be "inclusive of all students wishing to learn from a Christian viewpoint and underlying philosophy." Professors of the university sign a statement of faith annually. This policy has caused some controversy within academic circles, and was most recently covered in Maclean's. Professors come from varying faith backgrounds. As in line with the students, a mixture of Christian traditions are represented. Orthodox and Hebrew professors are also on staff. Approximately 80% of undergraduates enrolled self-identify as Christian. There are many Christian clubs, organizations, and ministries on campus. There is no compulsory participation in any religious liturgies. Students and clubs of other religious denominations are welcomed and supported. Nearly every resident hall has a Chaplain in residence. In the morning on every weekday there is Chapel, at which attendance is voluntary, and communion is offered on one Friday each month. Within the university Core, students are required four terms of Religious Studies. One term is allotted to a Survey of the Old Testament, and one to a Survey of the New Testament. Another term must be a class in Religious and Cultural studies. Catholic Pacific College, formerly Redeemer Pacific College, is the university's constituent Catholic college. CPC's Glover Road Campus is adjacent to TWU. CPC is administered separately of the university, offers classes in Catholic studies and a liberal arts curriculum is taught by a Catholic faculty. Mass is also offered four times weekly. Student groups Trinity Western's nearly 100 student organizations and clubs cover a wide range of interests. In 2011, the university hosted 11 academic groups, four cultural groups, five "issue-oriented" groups, eight performing groups, six pre-professional groups, three publications, and 13 recreational groups. Greek life is not sponsored by the university. Each year, the Foreign Affairs Society hosts a Model United Nations conference for high school students. The Trinity Western University Students Association is the elected government of the student body, and works as an aid and mediator between individual students and university administration, in addition to sponsoring several events throughout the academic year. Members of the university's chamber choirs are often invited to guest perform with the Vancouver Symphony Orchestra, performances which have been broadcast on a number of occasions on CBC Radio; as well, Trinity Western's choirs have performed frequently with the CBC Radio Orchestra,
