The Rorate Caeli Mass is uniquely beautiful, being candlelit and just before the crack of dawn. What an appropriate way to prepare for the coming of the Son of God.

Rorate, caeli, desuper, et nubes pluant justum, aperiatur terra, et germinet Salvatorem.

Drop down dew, ye heavens, from above, and let the clouds rain the just: let the earth be opened and bud forth a Savior.
