"The church is the assembly or fellowship of the people of God, constituted by the call of God, a people formed for himself to show forth his praise and to bear witness to him in the performance of prescribed functions, Matt. 16:18; 18:17," wrote John Murray in his Collected Writings, (Vol. I, page 232f). In criticizing the use of the word, "invisible" to describe the church, Murray said that "according to Scripture we should speak of 'the church' and conceive of it as that visible entity that exists and functions in accord with the institution of Christ as its Head, the church that is the body of Christ indwelt and directed by the Holy Spirit, consisting of those sanctified in Christ Jesus and called to be saints, manifested in the congregations of the faithful, and finally the church glorious, holy and without blemish." (pg. 236)
