Bede, Homilies on the Gospels 1.7 in Arthur A. Just, ed., Luke, Ancient Christian Commentary on Scripture (Downers Grove, IL: InterVarsity Press, 2005), 42:
The shepherds did not keep silent about the hidden mysteries that they had come to know by divine influence. They told whomever they could. Spiritual shepherds in the church are appointed especially for this, that they may proclaim the mysteries of the Word of God and that they may show to their listeners that the marvels which they have learned in the Scriptures are to be marveled at.
