“The Church is the community of all true believers for all time”. The term “church” is also used to reference the community of true believers in distinction to Israel. While the Church is comprised of a visible congregation of believers, the visible congregation is not solely comprised of true believers. Thus, the church may also be said to be invisible: “The invisible church is the church as God sees it.”
The church is universal, in that it comprises all believers and local in that it comprises local congregation of believers, “the community of God’s people considered at any level can rightly be called a church.”
Christ is the head, and the church is the body (Col. 2:19).
