God has laid down the foundation of the ministry and the calling of the church in his Word. The Bible teaches us the core principles of Church Polity. These principles are also accentuated in a systematic way in the Reformed Confessions namely the Canons of Dordt, the Heidelberg Catechism and the Belgic Confession and are expressed in the Church Order. Reformed Church Polity has to study these principles in view of the Word of God and the Reformed Confessions and provide guidelines for the sound and effective application of the Church Order in the church. The God-given task of the Church cannot be effectuated in a pragmatic way according to modern-day sociological and managerial principles. The church functions in a particular historical and cultural context. Therefore the principles of Church Order also have to be realized in such a way that they address the needs of the day and the situation of the church. Although the principles remain the same, a model of ministry should change in view of time and context. Lack of sound renewal of the church results in a formalized, traditionalistic and irrelevant church, which will be detrimental to the fulfillment of the calling of the church within the framework of the kingdom of God.
