Church membership does not save.

[Scoop140]

The Church has been described throughout the New Testament scriptures and throughout its history as individual believers with Christ as their Head. Pieper writes that this dissuades sinful man from imagining that his mere membership in a church organization or denomination is what guarantees his salvation. Christ's kingdom is not of this world; it is righteousness of heart and is a gift of the Holy Spirit (Pieper, Francis, 1953).
