ABSTRACT
This chapter looks at the evidence for levels of church going and what scope clergy and others saw for growth in the medieval church. It considers the medieval sources that explicitly discuss church growth. The chapter discusses concerning church growth theory, and the reality of church growth, in medieval European Christendom. Accurate statistics for church membership and attendance in the medieval past are notoriously absent, but the chapter considers what historical sources can be brought to bear on questions of church attendance and church growth. It explores the medieval sources that explicitly discuss church growth. The contemporary debate about the relative importance of numbers and depth is of course just as applicable in the medieval period as it is now and we will return to questions of depth of Christian commitment and spirituality at the end of the chapter.
