My blog’s headline, “One Body, One Faith, One Baptism,” comes from the book of Ephesians 4:4-6.
“There is one body and one Spirit—just as you were called to the one hope that belongs to your call— one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all.”Ephesians 4:4-6
Paul is talking about unity in these passages. He wants all Christians in Ephesus, even Christians today, to be “eager to maintain the unity of the Spirit in the bond of peace” (v. 3).
A recent article from Lausanne Movement points out how that unity is achieved. Henri Blocher says, “…the unification of all believers belongs to the real mission of the Holy Spirit. ‘One body’ first depends on ‘one Spirit.’ He goes not to say this is the main point of Jesus’ prayer in John 17:21. There Jesus prays, “…for those who believe through me… may all be one… so that the world may believe that you have sent me.”
In John 13-17 we get much of our insight into the person and the work of the Holy Spirit. In this context Jesus tells his disciples to love one another (13:34). Then Jesus says he will send a Helper (14:16) in order to help us follow his commandments to love one another, and to love Jesus and the Father. He will teach us all things and bring to remembrance all that Jesus taught (14:26). He will speak all truth and glorify Jesus in his people (16:12ff). Then Jesus prays that those who believe in him will be one in the same love that flows between the Father and the Son (17:20-21).
The fulfillment of Jesus’ promise came 10 days after his Ascension. While the disciples were in the upper room the Holy Spirit came upon them like a rushing wind and fire. The Holy Spirit indwells every believer unifying them in a unique way not seen outside the Church. Blocher says, “This order of events [in John 13-17 and then Acts 2] invites us to understand that the unification which will follow the fulfillment of the word of Christ and the coming of the Spirit are one single event.”
Jesus prays for unity among his people. And then he sent the Holy Spirit in order to answer his own prayer. The empowerment of the Holy Spirit in our lives is the key to unity among the churches.
