I was a little confused by this, too? I thought a vigil mass precedes the day itself?
[post=12238554]They do[/post].
I question the faulty reasoning: *
, there is a proper vigil mass*.
The five solemnities of the Nativity of Our Lord, Easter, the Nativity of John the Baptist, SS Peter and Paul, and the day in question, the Assumption of the BVM retain proper vigil Masses (on the day preceding the feast).
But (unless something was recently promulgated) the 12* solemnities of Mary the Mother of God, Epiphany, St Joseph the husband of Mary, the Annunciation, the Ascension, Pentecost, the Most Holy Trinity, the Body and Blood of Christ, the Sacred Heart of Jesus, All Saints, Christ the King, and the Immaculate Conception of the BVM do
not retain proper vigil Masses.
(* 19 if you count the days in the Octave of Easter)
