This book is a theological and practical treatise on the order of power and authority in the Church, expressed in terms of keys of authority and keys of liberty, and how they relate to each other for the proper functioning of pastors and members in a local church and among several local churches. The author presents and explains the key of authority and governance for elders (pastors), and the keys of liberty for members of the local church; in such a way that the extremes of the lack of authority of officers below the church as a whole are avoided, and also the tyranny of elders or a select group above the participation of the church as such is avoided, in addition to explaining the need and relationship between various churches.
