Martin LLoyd-Jones on homogenous churches

"…is there not a tendency in our work always to reproduce the same type? Do not our people always tend to be drawn from one particular type or class? If they are, there is something seriously wrong. Psychological methods and movements always tend to reproduce the same type, whereas it has always been the glory of the Christian faith that it has won its converts from all classes and all kinds of people. Our suspicions should be aroused at once if we find that we are tending to produce a people that are like peas in a pod, or like rows of postage stamps. That savours of the psychological, rather than of the spiritual." (Martyn Lloyd-Jones, Knowing the Times. Carlisle: Banner of Truth, repr. 2001. p. 85 - cited in Reformation 21)
