The Christian Union or CU in St Andrew's College is a welcome-to-all club where students meet, discuss and learn about Christian topics. The CU is run and organised by the senior members of the group and supervised by the Religious Education Department of the school.   It is a friendly, relaxed place to come, to eat, to listen and to participate in the Christian faith.   Guest speakers come in and talk, fun activities occur and a weekend away is organised in November every year.
