After their ejection from the Church of England, it is said that the English Presbyterians split into two factions. The ‘Dons’, led by Richard Baxter, pursued comprehension and reunion with the national Church, whilst the ‘Ducklings’ petitioned for an indulgence of their separation. In this article, it is argued that this twofold distinction is largely false. Rather, all English Presbyterians sought unity; their divergence in terms of practical policy stemmed from subtly different conceptions of catholicity. Thus, paradoxically, indulgence came to be seen as a pathway towards comprehension. Conventicle preaching, meanwhile, became a curious form of curacy, operating in tandem with the parish ministry.
