Derived probably from the Greek kuriakon (i.e., "the Lord's house"), which was used by ancient authors for the place of worship.
In the New Testament it is the translation of the Greek word ecclesia, which is synonymous with the Hebrew _kahal_ of the Old Testament, both words meaning simply an assembly, the character of which can only be known from the connection in which the word is found. There is no clear instance of its being used for a place of meeting or of worship, although in post-apostolic times it early received this meaning. Nor is this word ever used to denote the inhabitants of a country united in the same profession, as when we say the "Church of England," the "Church of Scotland," etc.
(4.) All the Christians in a particular city, whether they assembled together in one place or in several places for religious worship, were an ecclesia. Thus all the disciples in Antioch, forming several congregations, were one church (Acts 13:1); so also we read of the "church of God at Corinth" (1 Cor. 1:2), "the church at Jerusalem" (Acts 8:1), "the church of Ephesus" (Rev. 2:1), etc.
The church visible "consists of all those throughout the world that profess the true religion, together with their children." It is called "visible" because its members are known and its assemblies are public. Here there is a mixture of "wheat and chaff," of saints and sinners. "God has commanded his people to organize themselves into distinct visible ecclesiastical communities, with constitutions, laws, and officers, badges, ordinances, and discipline, for the great purpose of giving visibility to his kingdom, of making known the gospel of that kingdom, and of gathering in all its elect subjects. Each one of these distinct organized communities which is faithful to the great King is an integral part of the visible church, and all together constitute the catholic or universal visible church." A credible profession of the true religion constitutes a person a member of this church. This is "the kingdom of heaven," whose character and progress are set forth in the parables recorded in Matt. 13.
The children of all who thus profess the true religion are members of the visible church along with their parents. Children are included in every covenant God ever made with man. They go along with their parents (Gen. 9:9-17; 12:1-3; 17:7; Ex. 20:5; Deut. 29:10-13). Peter, on the day of Pentecost, at the beginning of the New Testament dispensation, announces the same great principle. "The promise [just as to Abraham and his seed the promises were made] is unto you, and to your children" (Acts 2:38, 39). The children of believing parents are "holy", i.e., are "saints", a title which designates the members of the Christian church (1 Cor. 7:14). (See BAPTISM.)
