The church is the people of God who have been saved through repentance and faith in Jesus Christ and have been incorporated into his body through baptism with the Holy Spirit.
John Calvin
Wherever we find the Word of God surely preached and heard, and the sacraments administered according to the institution of Christ, there, it is not to be doubted, is a church of God.
Thabiti Anyabwile
The church is that assembly of people who belong to the Lord, who are gathered together for him.
Mark Dever
The Church is not a growing number of people, but a number of people growing.
E.M. Bounds
The church is the only society in the world that never loses any of its members, even by death.
Dietrich Bonhoeffer
The church is not a religious community of worshippers of Christ but is Christ himself who has taken form among people.
