Is it permissible to have nocturnal adoration from the night of Holy Thursday into the morning of Good Friday?
After the Mass of the Lord’s Supper [on Holy Thursday], the faithful should be encouraged to spend a suitable period of time during the night in the church in adoration before the Blessed Sacrament that has been solemnly reserved. . . . From midnight onward, however, the adoration should be made without external solemnity, for the day of the Lord’s Passion has begun (Paschale Solemnitatis 56).While prolonged eucharistic adoration of the reserved—not exposed—Blessed Sacrament into the early morning hours of Good Friday is permitted, after midnight it should be silent adoration. When the adoration should end is not clearly defined by the document, but the wording of the rubric appears to indicate that the adoration should take place during nighttime hours.
