The true Church, built upon the Foundation of Jesus Christ (1 Corinthians 3:11; Ephesians 2:20), is the Body of our Lord (Romans 12:5; 1 Corinthians 12:27); Christ being the Head (Ephesians 1:22, 23; Colossians 1:18). Its earthly constituents are all true believers, born again of the Spirit (John 3:6) and of the Word (1 Peter 1:23), who are living an overcoming Christian life (Ephesians 5:27; Revelation 21:27). To the Church, through its members, are delegated the various gifts and offices of the Holy Ghost (1 Corinthians 12:7-11, 27, 28) which are necessary for the successful evangelization of the world and the perfecting of the Body of Christ (1 Corinthians 12:7; Ephesians 4:11, 12). This universal, invisible, sanctified Church is the chaste virgin Bride of Christ (1 Corinthians 1:1, 2; Ephesians 5:25-27; Revelation 21:9b, 27). It is this Bride for whom Jesus Christ will return, just prior to the Great Tribulation, to catch her away and take her to heaven (1 Thessalonians 4:13-18).
