After Mass, we begin Eucharistic Adoration. While the priest places Jesus on the altar, some kneel, some stand. When the priest begins singing “Holy God, We Praise Thy Name,” some of those kneeling stand, others stay kneeling, because at this point, the priest has come down from the altar and is facing the Monstrance and the acolyte is behind him with the crucifix. When he finishes the song, they turn around and walk out. When then song ends and they turn around, many of those who were kneeling, stand up. Others have been standing all along.
What are the correct rubrics please???
