“A convocation is a gathering of people who are convoked together by someone, and a church is a convocation called by God through Christ, and the modern idea of a convocation, there is an internal motive for us, a self-generated, a self-determined gathering, but a congregation should be a convocation, called by an external power by the power of Christ, the Lord. Thus, the church witnesses to the fact that it is a convocation, God’s holy convocation through Christ.”

— R. J. Rushdoony
