To the liturgy of the Reformed Churches belongs the Form For Excommunicating impenitent persons from the church of our Lord Jesus Christ. This form may be found in the back of our Psalters, along with our other Confessions. It may be divided into four main parts. The first part contains an informative section, in which the congregation is made aware of the sin and impenitence of the offender and the necessity of excommunicating him. This is followed by a short paragraph in which the act of excommunication itself is described.
