"Surely the aim of the whole operation must be the planting and perfecting of new colonies of heaven, new congregations of beautiful people... Missionary work has to be church-centred if it is to be effective... It needs to be strongly emphasied.. that the criterion for the success of an interdenominational group is the extent to which it contributes towards the building up of the church. Take a university Christian Union, for example. The test of its effectiveness is not the number of students who belong to it, or even the proportion of the membership who have been converted through its ministry... The test is long term, and is in the extent to which its former members are now integrated into and playing a part in the leadership of the local church.... they must be judged by the criterion of the benefits which they bring to the churches." *That's the kind of ministry I want to see through the Christian Unions of the South West of England.
