The CICCU organises weekly talks, explaining what Christians believe, and discussion groups (Christianity Explored courses). The college groups organise termly events in the colleges where people can come and find out more about Christianity. Every year there is a high-publicity main event, during which events are held in most of the colleges and there are lunchtime and evening talks. CICCU adopts the doctrinal basis of UCCF, to which it is affiliated. The doctrinal basis contains what is perceived as the biblical foundations of Christianity, including:   Attitudes towards homosexuality have been a particular area of controversy, in particular during their 2004 Promise Week event, in which it was alleged that homosexual relations were equated with bestiality. CICCU members deny that their organisation is anti-gay, stressing "equality in the sight of God", and point out that they love homosexual and heterosexual friends equally, as does God.. Recent comment on the CICCU has been more ambivalent – surprised by the intense focus on sharing rather than simply maintaining their faith, but impressed by the warmth of their welcome, and the depth of their conviction.
