It's disgusting but I am not particularly surprised as university Christian Unions, especially the UCCF affiliated ones (which I think Bristol is) are notorious for con-evo ridiculousness. The one at my own university wasn't quite this bad but they did all kinds of idiotic nonsense.
It's important to note that university Christian Unions usually by no means represent the majority of Christian students in an institution. They almost always have doctrinal statements that are designed to exclude Orthodox, RCs, High Anglicans and liberal Anglicans and Methodists from their leadership. They are anything but concerned with Christian unity, but they monopolise the term 'Christian' on campuses.
