25 years ago, New Zealander Viv Grigg made a case for identifying Protestant missionary movements with Catholic religious orders. The comparison was based on missionary statesman Ralph Winter’s own article, published the previous decade. On this description, South Africa is flooded with monastics! Seriously, though, the self-understanding of the Moravian church (see Steve Hayes’ comment below), for example, may support this thesis.
Before we entertain such a diversion, what about conventional orders of Protestant monks or nuns? The only community I’m aware of in this country is the Anglican ‘Order of the Holy Cross,’ Mariya uMama weThemba Monastery in Grahamstown. Are there other Protestant intentional communities?
