First Friday Adoration of the Blessed Sacrament begins 6:30 p.m. and ends prior to the 5:30 p.m. Mass every Friday Friday. Sign-up sheets are available in the Cathedral Center. Please consider signing up for Eucharistic Adoration. All empty time slots need to be filled prior to opening Adoration of the Blessed Sacrament. Otherwise, we will have to alter the Adoration hours. Holy Hour for Vocations is held immediately following the 6:00 a.m. Mass at the beginning of Adoration. This is a time for public and private prayer. Adoration is held in the Cathedral Center (St. Michael Hall) during the renovation of the Cathedral.
