Presbyterians admit the authority of the Presbytery or Synod over all worship services in order to ensure that the worship of God, Father Son and Holy Spirit, is carried on properly and regularly in each congregation within the 'bounds' (area of jurisdiction). This is done by the appointment of Ministers by the Presbytery, who can also dismiss (depose) the Ministers should their conduct of regular worship be unsatisfactory. In modern times an effective presbytery is a forum for discussing and disseminating approaches to worship, always recognizing the supreme authority of the Word of God (Old and New Testaments of the Bible).
