Joanna, whom Luke is the only Evangelist to mention by name, was surely his special channel of information that only he, among the Evangelists, seems to have had [about Jesus’ trial before Herod Antipas]. Married to a well-placed political figure in the Galilean court, Joanna was apparently a lady of some means, who used her resources to provide for the traveling ministry of Jesus and the apostles. Acting in this capacity, she must have been very well-known among the earliest Christians. Only Luke, however, speaks of her by name, a fact that seems to indicate that he had interviewed her in the composition of his gospel. We can guess that Joanna’s adherence to Jesus was not without its difficulties for her domestic life. Here she was, the wife of a high political official, providing support for someone who would die as a political criminal. Her loyalty was supremely rewarded, however, because the risen Lord saw fit to number Joanna among the holy myrrh-bearers, those surprised women who “came to the tomb bringing the spices which they had prepared,” found the stone rolled away from the tomb, then prostrated before the two herald angels of the Pascha, and subsequently “told these things to the apostles” (Luke 24:1, 5–7, 10). One suspects that Joanna also had a thing or two to tell her husband, Chuza, later that day.
