A plenary indulgence is granted to the faithful under the usual conditions who devoutly assist at the singing or recition of:
The Te Deum on the lst day of the year to give thanks to God for benefits received during the past year.
The Veni Creator on 1 January to implore divine help during the coming year.
As ever, do see my post Plenary Indulgences not impossible if you are worried about the conditions
In my parish, we have a Vigil from 11pm tonight. The Blessed Sacrament is exposed; we say the Glorious Mysteries of the Rosary and then the Office of Readings (in English) from the Liturgia Horarum, concluding with the Te Deum sung in Latin.
Tomorrow, we will sing the Veni Creator in Latin after Mass.
May I take this opportunity to wish you all a very Happy New Year.
