 Although not mentioned by name, Joanna is most likely counted as one of the women who joined the disciples and Mary, the mother of the Lord, in the upper room in prayer.She was among the group of 120 who chose Matthias to fill the vacancy that was left by Judas, as well as being present on the Day of Pentecost.Both Richard J. Bauckham and Ben Witherington III conclude that the disciple Joanna is the same woman as the Christian Junia mentioned by Paul in his "Epistle to the Romans" ().
