Two recent articles inRecusant Historyhave drawn attention to the Protestation Returns, and used them as evidence for the size and strength of the Catholic community in the seventeenth century, as well as for evidence for the existence or non-existence of ‘Church Papists’. The purpose of this article is to move the discussion on towards an examination of the reliability of the Protestation Returns themselves as giving an accurate picture of the size of the Catholic community, and, in particular, to examine the evidence in the case of the parish of Midhurst in West Sussex, a well-known centre of recusancy.
