According to the early church’s own self-narration in the book of Acts it would seem so. In Acts 2 clearly it is the pentecostal coming of the Holy Spirit which initiates the new messianic reality through the apostles. But, the logic of the Spirit’s movement is not Pentecost-Church-Mission, but Pentecost-Mission-Church. The Spirit descends upon the apostles (2:2-4) who then proceed to proclaim the gospel (2:14ff). Only after the proclamation, the enactment in the Spirit of their missional vocation, do the apostles baptize those who are caught up into the gospel’s truth. Only after the missional proclamation of the truth about Jesus does the rudiments of a common missional life, the life of the ekklesia, begin to emerge (2:42-46).
The church, then is a response to the pentecostal mission of the Spirit through the apostolic proclamation of the truth about Jesus. And this response is one of being given over to the form of radical love displayed in Christ’s own revelation of Israel’s God. It is a movement of fellowship, solidarity, service, and mutual dispossession (v. 45).
Thus, the logic of mission and church is something like the following: the messianic mission of Christ calls forth the pentecostal mission of the Holy Spirit which brings about the aposolic mission of proclamation in word and deed of the radical love of Jesus. This apostolic mission takes shape in the ekklesia, a movement of communal cruciform love and service to the world.
