Volume one of this two volume work entitled The Church of Christ deals with the nature and power of the Church, containing a lengthy explanation of the church in relation to the state, which is arguably one of the best treatments on this topic available. From there it deals with matters in regard to which church power is exercised (i.e. in regard to doctrine, ordinances, the instrumentality and time of public worship; with a discussion of holy days and confessions).
Volume two continues where volume one stopped and provides a lengthy section on the sacraments, covering the parties in whom the power to exercise church discipline is vested, examining crucial points concerning Christian liberty and examining and comparing various church forms. Nine appendices deal with a wide range of practical topics including union between churches, church/state relations, ordination, and valuable notes on the literature related to this subject.
