Unity: the Real and the Counterfeit
There is only one Church of Jesus Christ, his Body and his Bride. In the upper room before his death he prayed that the Father would glorify him (John 17:1-5), that the Father would sanctify his Apostles in the Truth (John 17:6-19) and that his Church may be one, so that the world may believe (John 17:20-26).
All three requests were answered through his death, his resurrection, his ascension and in the gift of the Holy Spirit. The prayer sees the foundation of a church one, holy, catholic and apostolic. In particular it is one.
That is why the Apostle Paul can say in these glorious words, “There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female, for you are all one in Christ Jesus” (Galatians 3:28).
