A discourse concerning the publick worship of God : Being an enquiry: first, concerning the nature of publick Christian worship; consider'd in both its parts, essential and circumstantial. Secondly, concerning the manner of its performance. Thirdly, concerning the liturgy of the Church of England; wherein is shewn, how well it answers the ends of publick devotions. By Henry Caner, A.M. [Six lines of Scripture texts].
