Apologia: The Fullness of Christian Truth

``Where the Bishop is, there let the multitude of believers be;
even as where Jesus is, there is the Catholic Church'' Ignatius of Antioch, 1st c. A.D

The Canonical Hours

The Romans divided the hours of the day and night into two twelve-"hour" periods, with each twelve-"hour" period related to hours of lightness and darkness -- i.e., with one of the periods starting at sunrise, and the other at sunset. Hence, throughout the year, the length of "an hour" would change, for example, being equal during the Equinoxes, but longer at night and shorter during the day in Winter time. 

Sunrise indicated the beginning of the first of the 12 hours, so sunrise would be "the first hour." When the Sun was overhead would be "the sixth hour." Sunset would indicate the beginning of the second set of 12 hours, so sunset would be "the first hour" of night, and midnight would be "the sixth hour." And so forth.

The first hour of each twelve hour period was called "hora prima"; the second "hora secunda," the third "hora tertia," the fourth "hora quarta," the fifth "hora quinta," the sixth "hora sexta," the seventh "hora sexta," the seventh "hora septima," the eighth "hora octava," the ninth "hora nona," the tenth "hora decima," the eleventh "hora undecima," and the twelfth "hora duodecima."

Now, Temple-era Jews devoted certain hours of the day to prayer:
Psalms 54:17
Evening and morning, and at noon I will speak and declare: and he shall hear my voice.

Psalm 119:164
Seven times a day I have given praise to thee, for the judgments of thy justice.

Daniel 6:10
Now, when Daniel knew this, that is to say, that the law was made, he went into his house: and opening the windows in his upper chamber towards Jerusalem, he knelt down three times a day, and adored and gave thanks before his God, as he had been accustomed to do before.

Daniel 9:21
As I was yet speaking in prayer, behold the man, Gabriel, whom I had seen in the vision at the beginning, flying swiftly, touched me at the time of the evening sacrifice.

This Old Testament practice was carried on by the Apostles, as recorded in the New Testament, using Roman timekeeping --

Acts 3:1
Now Peter and John went up into the temple at the ninth hour of prayer.

Acts 10: 3
This man saw in a vision manifestly, about the ninth hour of the day, an angel of God coming in unto him and saying to him: Cornelius.

Acts 10:9
And on the next day, whilst they were going on their journey and drawing nigh to the city, Peter went up to the higher parts of the house to pray, about the sixth hour.

Acts 10:30
And Cornelius said: Four days ago, unto this hour, I was praying in my house, at the ninth hour and behold a man stood before me in white apparel and said:

Acts 16:25
And at midnight, Paul and Silas, praying, praised God. And they that were in prison heard them.

And, of course, these daily prayers spread and were prayed by other of the earliest Christians. These times of official prayer developed into the Church's "canonical hours" or "offices" at which certain prayers (psalms, canticles, antiphons, responsories, etc.) are prayed. These prayers are known as "The Divine Office" (Officium Divinum), the "Liturgical Office," "The Liturgy of the Hours," or "The Breviary" (the latter term also applying to the "book of hours" which contains the prayers). The names of many of the day's prayer times take their names from the Roman words for those hours.

St. Benedict (A.D. 480-543) writes of the canonical hours in the Rule he wrote for his religious Order:

As the Prophet saith: "Seven times a day I have given praise to Thee," this sacred sevenfold number will be fulfilled by us in this wise if we perform the duties of our service at the time of Lauds, Prime, Tierce, Sext, None, Vespers, and Complin; because it was of these day hours that he hath said: "Seven times a day I have given praise to Thee." For the same Prophet saith of the night watches: "At midnight I arose to confess to Thee." At these times, therefore, let us offer praise to our Creator "for the judgments of His justice;" namely, at Lauds, Prime, Tierce, Sext, None, Vespers, and Complin; and let us rise at night to praise Him.

These prayers of the Divine Office are most often said by religious and clergy (in fact, they are obligated), but because they are liturgical in nature -- i.e., they are "the work of the people" -- they should be offered publicly in churches (especially Matins and Vespers). When they are celebrated publicly, there are established norms for postures and such, but these prayers are often said, also, by lay individuals and families, some saying only certain offices as they are comfortable with, have the time for, and as it feeds their souls (usually Matins, Lauds, and Vespers).

The canonical offices are below. I include the Novus Ordo version for informational purposes:

This office originally consisted of four "watches," or "vigils": 6PM-9PM, 9PM-Midnight, Midnight-3 AM, and 3 AM-6 AM.

Later it consisted of three "nocturnes," 9-Midnight, Midnight-3 AM, 3 AM-6 AM.


Originally this office was known as "Vigils" or the "Night Office," but because the next office, Matins, ended up being the closing part of Vigils, often they both began to be called "Matins." Some traditional Orders still keep Vigils separately.

Some of the stricter religious Novus Ordo orders (especially the contemplative ones) might still keep Vigils in some form or another, but most don't


(pronounced "MATT'-inz")

See above and below. Matins, called "Orthros" in the Eastern Churches, includes the three Nocturnes that once belonged to Vigils.

The sunrise office known as "Matins" has been transformed into the "Office of Readings" which can be said at any time of the day.

(pronounced "lawds")

The word means "The Praises." Matins and Lauds were originally one, single office sung at dawn. After Vigils started to be callled "Matins," Matins started to be called "Lauds."

Lauds or "Morning Prayer" or "The Praises"

6:00 AM (the "first hour")



9:00 AM (the "third hour")

(pronounced like "terse")

Called collectively "The Little Hours" or "Prayer through the Day," they are still called individually "terce," "sext," and "none." Only one of these short offices is obligatory for clergy/religious or those wanting to pray the complete Divine Office.

noon (the "sixth hour")


3:00 PM (the "ninth hour")

(rhymes with "bone")



Vespers or "Evening Prayer" or "Evensong"

after sunset, before bed

(pronounced "COMP'-lin")

Compline or "Night Prayer."
