St. Benedict in his Rule wrote concerning prayer, “ ‘Seven times in the day,’ says the Prophet [psalmist], ‘I have rendered praise to you.’ Now that sacred number of seven will be fulfilled by us if we perform the offices of our service at the time of the morning office, of prime, of terce, of sext, of none, of vespers and of compline, since it was of these day hours that he said, ‘Seven times in the day I have rendered praise to you.’ For as to the night office the same Prophet says, ‘In the middle of the night I arose to glorify you.’ ” 

Today priests, bishops, religious, and a surprising number of lay Christians pray through the day using the Daily Office. Msgr. Daniel Seiker, Wyoming Catholic College's Latin chaplain, explains what it means to pray the office and why it's important.
