The book of Acts presents an informative view of the Church, as well as an informative view of the way in which the Church read the Scriptures. As they saw that all things spoke of Jesus Christ, they also went on to apply those things to themselves. They lived the life of Christ.
This can be seen in Acts 4. Peter and John get in trouble for healing a lame man and preaching on the resurrection at Solomon’s portico, and so they are hauled before the Sanhedrin. When they return to the fellowship of the believers and relay their story, the group begins to pray Psalm 2 (vs. 23-31). They explicitly connect the characters in Psalm 2 to the characters at Jesus’ crucifixion. Jesus is the Annointed. Herod, Pontius Pilate, the Jews, and the Gentiles are the heathens, nations, and kings and rulers. This much is clear.
What is often missed, however, is that the actual application of this Psalm is not simply to the death of Christ, but to the events that just occurred. The ones gathered against were Peter and John. The “threats” which the Church calls for the Lord to look on in vs. 29 are those threats of vs. 21.
Thus it is quite appropriate for this incident to be followed with the description of the believers holding all things in common. They are of one heart and one soul precisely because they are the one Body of Christ. The giving of the land is the inheritance of the nations, and that they are laid at the apostles’ feet is Christological imagery (Gen. 3:15, Psalm 110).
So the anointed who was conspired against by the rulers and the nations was indeed Jesus, but it is also the Church. We, as the baptized, are all anointed ones, and as we dwell together, we are the one Body of Christ. Our life is Christ’s life, and what is done to us, and in turn what we do to one another, is done to Jesus.
