"I do believe that the concept of the Universal Church is a fantasy."
Not seeking discussion, just info. Most that believe in universal church see it as all church saints, dead and alive. Why do you not believe in it when you seem to realize it exits when you say. "God has always had a witness on this earth. "The gates of hell shall not prevail against it" you know."
One must ask, for what purpose does the Universal Church exist? It does nothing. It does not assemble, does not worship together, does not have a teaching function, sends no missionaries, gives no money, prints no Bibles, distributes no Bibles. When was the last time the Universal Church observed the Lord's Supper"
Then, we must example the Greek word translated "church."
Ecclesia has as its original meaning a "gathering of citizens called out from their homes to a public place (Thayer's Lexicon). The simple meaning is "assembly." When it is used in the New Testament, that's what it means.
The problem comes when people confuse the church and the Kingdom.
Thomas Paul Simmons, in his book
A Systematic Study of Bible Doctrine (1935) makes the following points:
(1) The church is an assembly; the kingdom is the domain of the King.
(2) The church as an assembly is necessarily local; the kingdom is universal.
(3) The church is spoken of as that which was to be built (Matt. 16:18); the kingdom is never thus spoken of.
(4) Christ said: "Tell it to the church" (Matt. 18: 17); no such command is ever given concerning the kingdom.
(5) The church is called a body (Eph. 1:22,23; Col. 1: 18; 1 Cor. 12:27); the kingdom is never thus spoken of.
(6) The church is a democracy under the headship of Christ..... the kingdom is a monarchy.
(7) Therefore the church has organic character, being visible and having officers (1 Cor. 12:28); the kingdom is neither organic or visible (Luke 17:20).
(8) Church membership is subject to the democratic action of the body (Rom. 14:1; Acts 9:26; 1 Cor. 5:5; 2 Cor. 2:6); while God, purely independent of church action, puts men in His kingdom by the new birth (John 3:5; Col. 1:13).
(9) The kingdom was preached and, at one time, was announced as at hand (Acts 20:25; 28:31; Mark 1:15); but such language is never used with reference to the church.
(10) We read of the gospel of the kingdom (Mark 1: 14; Matt. 4:23; 9:35; 24:14); but never of the gospel of the church.
On occasion we will find
ecclesia used in the abstract institutional or generic sense, in the same way we use terms such as home, marriage, family, man.
For instance, I Corinthians 12:28:
And God hath set some in the church......
Another: Ephesians 5:25
Husbands, love your wives, just as Christ also loved the church and gave Himself for her,
Individual husbands love real, concrete, individual wives, not some generic wife or universal wife.
There is a prospective sense, as well. Hebrews 12:23
To the general assembly and church of the firstborn which are written in heaven, and to God the Judge of all, and to the spirits ofT the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect,
This is an obvious reference to heaven, since it refers to an assembly. This assembly of all believers can take place in only one place. It has never been true on earth. So this is used prospectively.
I know this has been long, but wanted to do justice to a sincere question.
