===Byzantine Rite===
In the [[Byzantine Rite]] (used by the [[Eastern Orthodox]] and some [[Eastern Catholic Churches]]), the Gloria is referred to as the ''Doxology'', and there are two forms: the Greater Doxology and the Lesser Doxology. The Greater Doxology is always sung, whereas the Lesser Doxology is read. There are certain textual differences between the two, and the order is somewhat altered in the two forms.

The Greater Doxology is used in the [[Matins|Orthros]] (Matins) on [[Sunday]]s and [[feast day]]s. The Lesser Doxology is used at Matins on simple weekdays and at the [[Compline|Apodeipnon]] (Compline), but not in the  [[Divine Liturgy]].<ref name=CE/>

=== Alexandrine Rite ===
In the [[Alexandrine Rite]] (used by the [[Coptic Orthodox Church]] and some other [[Oriental Orthodox Churches]]), the Gloria is a common congregational prayer, sometime referred to as the "Praise of the Angels". It is recited collectively by the congregation during the Morning Raising of Incense, as well as at the Matins prayer of the [[Agpeya]] (the Alexandrian Canonical [[Book of hours|Book of the Hours]]).<ref name=":0">{{Cite book |url=https://tile.loc.gov/storage-services/service/music/coptic/200155823/200155823.pdf |title=The Divine Liturgies of Saints Basil, Gregory, and Cyril |publisher=St. Mary & St. George Coptic Orthodox Church |year=2001 |location=Tallahassee, Florida, USA |pages=29;210}}</ref><ref>{{Cite book |url=https://ukmidcopts.org/kotob/Agpia.pdf |title=AGPIA |publisher=Coptic Orthodox Publication and Translation |year=2000 |location=Sydney, Australia |pages=24}}</ref> The first verse of the hymn is also recited at the dismissal of the Divine Liturgy before the chanting of the "Concluding Canon".<ref name=":0" /> 

===Roman Rite===
By contrast, in the [[Roman Rite]] this hymn is not included in the [[Liturgy of the Hours]], but is sung or recited at [[Mass (liturgy)|Mass]], after the [[Kyrie]], on Sundays outside of [[Lent]] and [[Advent]], during the [[octave (liturgy)|octaves]] of Easter and Christmas, and on [[solemnity|solemnities]] and feasts.<ref name=ODCC/>

In Masses celebrated in accordance with the 1962 [[Roman Missal]] (authorized as an [[Summorum Pontificum|extraordinary form]] of the Roman Rite), the Gloria is sung much more frequently: the 1960 [[Code of Rubrics]] require it at Mass when in the corresponding Office of the day the [[Te Deum]] is said at [[Matins]]. It is thus used not only on I and II-class feasts (corresponding to solemnities and  feasts in the [[Mass of Paul VI|post-Vatican II Mass]]) but also on III-class feasts (corresponding to [[memorial (liturgy)|memorials]] in the later form). In the 1962 form it is also said on ferias of [[Christmastide]] and [[Paschaltide]] even outside the octaves, but is omitted during the [[Septuagesima]] season, which does not exist in the post-Vatican II liturgy. The Gloria is also sung in both the pre-Vatican II and in the later form of the Roman Rite at the [[Mass of the Lord's Supper]] in the evening of [[Maundy Thursday]] and at the [[Easter Vigil]].<ref>{{cite book|editor-last1=Murphy|editor-first1=Patrick L. |title=The New Rubrics of the Roman Breviary and Missal|date=1960|publisher=Catholic Press Newspaper Co.|location=Surrey Hills, New South Wales, Australia|page=81}}</ref>

A tradition recorded in the [[Liber Pontificalis]] attributes to [[Pope Telesphorus]] (128–139?) the use of the hymn at the Mass of [[Christmas Day]] and to [[Pope Symmachus]] (498–514) its use on Sundays and the feasts of [[martyr]]s, but only by bishops; the right to use it was later extended to priests, at first only at [[Easter]] and on the day of their ordination, but by the end of the 11th century priests, as well as bishops, used it in the Mass on Sundays and feasts outside of Lent and [[Septuagesima|Pre-Lent]]. After the 12th century [[Advent]] began to be considered a penitential period in imitation of [[Lent]], to the exclusion therefore of the {{lang|la|Gloria in excelsis Deo}}.<ref name=CE/>

===Lutheran Rite===
The hymn is used in the [[Mass (liturgy)#Lutheranism|Mass]] ([[Divine Service (Lutheran)|Divine Service]]) of the [[Lutheran Church]]es.<ref>{{Cite web|url=https://lutheranreformation.org/worship/the-gloria-in-excelsis/|title=The Gloria in Excelsis|date=December 24, 2016}}</ref> 

===Anglican use===
In the [[Church of England]]'s [[Book of Common Prayer (1549)|1549 edition]] of the ''[[Book of Common Prayer]]'', it was used in the same position as in the Roman Rite but was later moved to the end of the service, immediately before the concluding blessing.<ref name=ODCC/> Revisions to the Prayer Book produced the [[Book of Common Prayer (1552)|1552 prayer book]] and later the [[Book of Common Prayer (1662)|1662 prayer book]], but this placement was retained by the [[Anglican Communion]] until the 20th century. ''[[Common Worship]]'' provides two Orders, one of which places the hymn in the earlier position.

The 1789 [[Episcopal Church (United States)|Protestant Episcopal Church in the United States of America]] prayer book placed the Gloria at the end of the psalms in Morning Prayer and Evening Prayer as an option to use of the Gloria Patri and also placed the Gloria at the end of the holy Eucharist (like the 1662 prayer book). The 1928 version removed the Gloria from Morning Prayer but retained it in Evening Prayer. This 1928 edition is still the standard in the breakaway [[Continuing Anglican]] churches. The Episcopal Church's 1979 Book moved it to the beginning, after or in place of the ''Kyrie'' in Rite One. In a Rite Two (i.e., contemporary language) service of Holy Eucharist, the Gloria, or another song of praise, is sung or said on all Sundays except those in Advent or Lent. It may also be used at other times as desired excepting Lent and Advent.
