In Roman Catholicism there exists a daily pattern of prayer, where specific prayers are linked to particular times of the day, a practice which dates from Medieval times. This cycle of prayer is typically undertaken by those in a monastic order. Some adherents believe that this Divine Office, as it is also called, reflects not just the passage of a single day, but also mirrors the life stages of a person. Here is one interpretation of these correspondences:
Lauds (Dawn Prayer) – (about 5 am) – Infancy – when we rose from night into day into the protection of our mothers.
Prime (Early Morning Prayer) – (about 6 am) – Childhood – when we (e.g. monks and nuns) began to memorize sacred texts and reflect on our service to God
Terce (Mid-Morning Prayer) (about 9 am) – Adolescence – when we received orders (e.g. entered a monastic order)
Sext (Midday Prayer) (around 12 noon) – Youth (e.g. Early to Mid-Adulthood) – when we were chosen as leaders and teachers of the people (i.e. elevated to the position of deacons and priests)
None (Mid-Afternoon Prayer) (approximately 3 pm) – Old Age – when most clergy take on ecclesiastical offices (e.g. bishop, major superior, parish priest, diocesan director of Catholic education etc.)
Vespers (Evening Prayer) (about 6 pm) – Decrepitude (e.g. Dying) – when most clergy will move on to a better place
Compline (Night Prayer) (about 7 pm) – Death – when we reflect upon the end of our lives and hope to be saved by confession and penance.
