"We are to become nothing less than the vanguard display of God's ultimate plan for the whole cosmos! As trans-local ministries ignore denominational boundaries and cross-fertilise diverse congregations they will help break up the lonely, isolated and in some cases fiercely independent ethos of many Christian groups ... it is futile to pray for unity and expanding mission whilst at the same time disparaging the instruments that God uses to effect this".
