The smallest truly Christian denomination or organization….
If two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven. For where two or three are gathered together in my name, there am I in the midst of them. -
Matthew 18:19-20
Which, in Christianity has resulted in thousands of denomination or organizations.
Candlesticks - Seven church congregations - The seven churches - Revelations 1:20
Stars - Individuals within the congregations, all held in the right hand of Christ
Seals - The seven seals sealed each congregation within the lambs book of life
So I believe the church congregations as seven and Christ walks in the midst of all of us. This forms one church, but there are many differences and denominations among us...
Messianic - The original church
Martyr - Oriental church beginning with Paul
Pergamos - Orthodox church beginning at Constantinople
Thyatira - Catholic church beginning at Rome
Sardis - Protestant church beginning in Germany
Philadelphia - Revived church beginning in England
Laodicean - Materialistic church beginning in America
If I had to pick I would consider Jesus Christ Messianic his time on earth which was still under the first covenant. What marked the end of the first covenant…
10 And I took my staff, even Beauty, and cut it asunder,
that I might break my covenant which I had made with all the people.
11 And it was broken in that day: and so the poor of the flock that waited upon me knew that it was the word of the Lord.
12 And I said unto them, If ye think good, give me my price; and if not, forbear. So they weighed for my price thirty pieces of silver.
13 And the Lord said unto me, Cast it unto the potter: a goodly price that I was prised at of them. And I took the thirty pieces of silver, and cast them to the potter in the house of the Lord.
14 Then I cut asunder mine other staff, even Bands, that I might break the brotherhood between Judah and Israel. - Zechariah 11
Then one of the twelve, called Judas Iscariot, went unto the chief priests, And said unto them, What will ye give me, and I will deliver him unto you? And they covenanted with him for thirty pieces of silver. - Matthew 26:14-15
The church age, the, began in Acts noting there has been many changes and variations since.
