I said I would look at the idea of calling on the name of the Lord Jesus in order to round off a little flurry of posts on the relation between Jesus and God in the context, particularly, of Luke’s narrative in Acts. The aim is neither to undermine nor defend Trinitarian orthodoxy. It is to try to imagine how the apostles and the early churches located the risen Jesus, not simply in relation to the Father but as part of a story that was being told.
In the minds of the apostles Jesus was the “Son” sent to Israel who had been rejected and killed by the leaders of the people and their Roman overlords, but who had been raised from the dead and elevated—in a more or less literal fashion—to the right hand of God in heaven.
This resurrected Messiah or “Son of God” was revealed to Paul on the road to Damascus, bringing him in line with the Jerusalem apostles (Gal. 1:15-16; 1 Cor. 15:8-9). He was also revealed in more visionary experiences at critical junctures—for example, to Stephen on the point of death, as the Son of Man who had likewise suffered but had been vindicated by God (Acts 7:55-56).
