Scriptural References
Alphaeus is named in the New Testament chiefly through his children. He appears in the lists of the Twelve, where James is identified as the son of Alphaeus (Matthew 10:3, Mark 3:18, Luke 6:15, Acts 1:13), and in Mark 2:14, where Levi—identified in tradition with the Evangelist Matthew—is likewise called the son of Alphaeus.
These references are the basis for the Eastern tradition that James and Matthew were brothers, sons of one father. The Western tradition has sometimes proposed two distinct men named Alphaeus to account for the two apostles separately, and some early writers connected the name with Clopas; the figure named in the lists of the Seventy is, in Orthodox usage, the single father from Capernaum.
