'Church of God' in the Bible

[it is being sent] to the church of God at Corinth. [You people are] set apart in [the fellowship of] Christ Jesus and called [by God] to be saints [i.e., His holy people], along with all [others] everywhere who call on our Lord Jesus Christ [i.e., in prayer]. He is their Lord and ours [as well].

Do not [do what could] cause Jews, Greeks [i.e., Gentiles] or the church of God to fall [away from God].

Do you not have houses to eat and drink in? Or, do you despise the church of God and put to shame those people who do not have anything [to eat]? What should I say to you? Should I commend you for doing this? Certainly not!

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