The new Missal, finally, contains propers for the Vigil of Epiphany. The readings (including the psalm) are the same for the Vigil and the Day. The collects, offertory prayer and communion prayer are different. So, too, the spoken entrance and communion antiphons (which would be used for those unusual weekend Masses without music). Whose celebrants know this? If you were the parish liturgist, would you proactively advise the parish priests?
Does this feast need its own Vigil readings? What gospel would possible work for this? John 1:10-13? What about the other readings? Baruch 5:5-9? Psalm 2?
