For a recent argument, by a Roman Catholic New Testament scholar, that this is the most probable implication of the New Testament evidence, see John P. Meier, A Marginal Jew: Rethinking the Historical Jesus, 2 vols. (New York: Doubleday, 1991–1994), vol. 1, pp. 316–332, and “The Brothers and Sisters of Jesus in Ecumenical Perspective,” Catholic Biblical Quarterly 54 (1992), pp. 1–28. For a critique of Meier’s arguments, see Richard Bauckham, “The Brothers and Sisters of Jesus: An Epiphanian Response to John P. Meier,” Catholic Biblical Quarterly 56 (1994), pp. 686–700.
