'Church of God' in the Bible

Take heed therefore to yourselves, and to all the flock, over which the Holy Ghost hath made you bishops, to feed as shepherds the church of God, which he purchased with his own blood.

to the church of God which is at Corinth, sanctified in Christ Jesus, to the called saints, with all those who invoke the name of our Lord Jesus Christ in every place, both their's and our's:

Give no occasion of stumbling either to the Jews or the Gentiles, or the church of God:

What! have ye not houses to eat in and to drink? or despise ye the church of God, and make those ashamed who have none? What shall I say unto you? shall I praise you in this? I praise you not.

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

PAUL an apostle of Jesus Christ by the will of God, and Timothy a brother, to the church of God which is at Corinth, with all the saints which are in all Achaia:

For ye have heard of my former manner of life, when I professed Judaism, that in the most outrageous manner I persecuted the church of God, and wasted it:

for if a man knoweth not how to order his own family, how shall he take proper care of the church of God?
