THE OFFICIAL NAME: CHURCH OF GOD

Catholics say, the church has no official name, thus their privilege of inventing a name for their church. But clearly, God gave an official proper name for the church as it say:

Ephesians 3:14-15

[14]For this cause I bow my knees unto the Father of our Lord Jesus Christ,

[15] ek (after) whom the whole family in heaven and earth is named…

As you can see, the family of god–the church–is named after God, so as corroborative to what god declared before:

Dan 9:19 

Thy people are called by thy name..

So the people of god, his family, the church is called by god’s name as how Israel was called by god: my people, indirectly saying, people of god. Its calling them by god’s name: god. Likewise, they were called the city of YHWH, that is calling them by god’s name YHWH. 

And god saying, his family is named after him and then we see the church called as church of god implies the church was named as official name, the church of god.

Why is it an official name?

Bec God said, the church is named after him. Is it a title name or proper name?

Whatever. But obviously, God officiated and declared an official name for the church.

If god said, your name is after me? Does it mean, that is not an official name when god confirmed its name? And saying, thy people is called by thy name? Does it not suggest that when the church was named after god it is naming the church after god’s name thus when the church is called church of god, being called by god’s name and after god, makes church of god an official name and god as god’s  name, the church being called in his name, God, as suggested: “thy people is called by thy name” & “the family of god is named after god“?
Logically?

The logic entailed in this contextual reality would make church of god as an official name and god by itself, a name of god! Read and understand: 

Ephesians 3:14-15

[14]For this cause I bow my knees unto the Father of our Lord Jesus Christ,

[15] ek (after) whom the whole family in heaven and earth is named…

As you can see, the family of god–the church–is named after God, so as corroborative to what god declared before:

Dan 9:19 

Thy people are called by thy name..

To God be the glory
