Jesus told the Samaritan woman that one day people would worship neither in Jerusalem nor on the mountain in Samaria, but that “the hour is coming, and is now here, when the true worshipers will worship the Father in spirit and truth, for the Father is seeking such people to worship him.” If then the church does not consist in a place of worship, nor in outward forms, but in spirit and in truth, then we may truly speak of an ‘invisible church.
However, this Spirit is active; it is this Spirit which obeys the Word to create. This Truth is also incarnate, for he hung on the cross and rose from the dead to give life. So if the Church visible wants to excuse its divisions and its lack of faith in actions of love by saying that it is only the ‘invisible church’ dwelling within the visible church that matters, then it has unwittingly confessed its estrangement from the true church of Christ. If one is truly a part of the invisible, spiritual church, then one will seek to bring about the visible unity of that church. For the Father is seeking such people to worship him.
