'Church of God' in the Bible

to the church of God which is in Corinth, to those who are sanctified in Christ Jesus, called out with all those in every place who call on the name of Jesus Christ our Lord, both theirs and ours.

Give no offense, either to the Jews, or to the Greeks or to the church of God;

For do you not have houses in which to eat and drink? Or do you despise the church of God, and shame those who do not have? What shall I say to you? Shall I praise you for this? I do not praise you!

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