Whose church is it?

Cousin,

I just noticed that Acts 20:28 makes mention of "the church of God." This is a common term in the New Testament.

To the church of God in Corinth, to those sanctified in Christ Jesus and called to be holy, together with all those everywhere who call on the name of our Lord Jesus Christ—their Lord and ours:(1 Corinthians 1:2)

Do not cause anyone to stumble, whether Jews, Greeks or the church of God— (1 Corinthians 10:32)

If anyone wants to be contentious about this, we have no other practice—nor do the churches of God. (1 Corinthians 11:16)

Don't you have homes to eat and drink in? Or do you despise the church of God and humiliate those who have nothing? What shall I say to you? Shall I praise you for this? Certainly not! (1 Corinthians 11:22)

For I am the least of the apostles and do not even deserve to be called an apostle, because I persecuted the church of God. (1 Corinthians 15:9)

Paul, an apostle of Christ Jesus by the will of God, and Timothy our brother, To the church of God in Corinth, together with all the saints throughout Achaia: (2 Corinthians 1:1)

For you have heard of my previous way of life in Judaism, how intensely I persecuted the church of God and tried to destroy it. (Galatians 1:13)

Yet, Romans 16:16 reads:

"Greet one another with a holy kiss. All the churches of Christ send greetings."

We see the words "God" and "Christ" used interchangeably.

Furthermore, the church of God is sometimes referred to as "the body of Christ" in Scripture (1 Corinthians 12:27, Ephesians 4:12).

This is another "clue" regarding Jesus' identity.
