'Church of God' in the Bible

to the Church of God at Corinth, to those who are sanctified in Christ Jesus, called to be saints, together with all, wherever they are, who call upon the name of the Lord Jesus.

Do not be a cause of stumbling either to Jews of to Gentiles, or to the church of God.

What! Have you no houses in which to eat or drink? or do you wish to show your contempt for the church of God, and to shame those who have no homes to eat in? What shall I say to you? Shall I praise you? In this I certainly do not praise you.

For I am the least of the apostles, I who am not worthy to be called an apostle, because I persecuted the church of God.
