The second stage in the growth of the Church was its spread throughout
Judea and Samaria, as recorded in Acts 8.
Antioch, in Syria, then became the head of the Gentile Church (Acts 13:1), as Jerusalem was the head of the Jewish Church (Acts 15); Paul representing the Church at Antioch, and Peter and James at Jerusalem. The assembly at Antioch was called "the church" just as truly as was the assembly at Jerusalem (11:22; 13:1).
Because of the missionary activities of the apostles, especially
Paul, churches sprang up in different cities, especially in Asia
Minor, e.g., Corinth, Galatia, Ephesus, and Philippi.
In view of all this the term "church" came to be used of the Church universal, that is, the complete body of Christ as existing in every place (1 Cor. 15:9; Gal. 1:2, 13; Matt. 16:18); of local churches in any one place (Col. 4:16; Phil. 4:15; 1 Cor. 1:2, etc.); of single meetings, even where two or three met together (Matt. 18:19; Col. 4:15; Phil. 1:2; Rom. 16:5).
It is evident, then, from what has here been said, that by the term "church" is included all that is meant from the Church Universal to the meeting of the church in the house. Wherever God's people meet in the name of Christ to worship, there you have the Church.
3. DISTINCTIONS:
a) The Church and the Kingdom.
The Church (which is the mystery) and the Kingdom in mystery are now contemporary. The Kingdom will be fully manifested at the coming of Christ. The Church is within the Kingdom; probably the regenerate are "the children of the kingdom." The Kingdom is comprised of both good and bad (Matt. 13); the Church, of real saints only. The Jews rejected the Kingdom under Christ and the apostles. That Kingdom, now rejected, will be set up again when the Messiah comes. This conception will help us to understand the parables of Matthew 13, as well as the Sermon on the Mount. The tares are sown not in the Church, but in the field, which is the world. The Church may be looked upon as part of the Kingdom of God, just as Illinois is part of the United States. The Kingdom is present, in a sense, just as the King is present in the hearts of his own people. There is a difference between the Church and Christendom, just as there is a difference between possessing and professing Christians. Baptized Christendom is one thing, and the Church of Christ is another.
b) The Church Visible and Invisible: Actual and Ideal.
The Church Visible is composed of all those whose names are enrolled upon its roster; Invisible, of those whose names are written in the Lamb's book of life; Actual, people imperfect, yet aiming after perfection, alive here on the earth; Ideal, departed saints who are now triumphant in heaven (Heb. 12:23). There is a Church in heaven just as there is one upon the earth; indeed, it is but a part of the one Church; called the Church militant while upon the earth, and the Church triumphant in heaven.
