Gloria Patri

[2] The Trinitarian doxology addressed in parallel fashion to all three Divine Persons of the Trinity, joined by and (καί), as in the form of baptism, Matthew 28:19, became universal in Nicaean Christianity, which was established as the official faith of the Roman Empire with the Edict of Thessalonica in 380.

A variant found in Common Worship has "shall" instead of "will": (In the third person, "shall"—as opposed to "will"—implies a degree of promise on the part of the speaker over and above mere futurity.

In the Roman Rite, the Gloria Patri is frequently chanted or recited in the Liturgy of the Hours principally at the end of psalms and canticles and in the responsories.

The prayer also figures prominently in pious devotions, notably the Rosary, where it is recited at the end of each decade.

Lutherans have historically added the Gloria Patri both after the chanting of the Responsorial Psalm and following the Nunc Dimittis during their Divine Service, as well as during Matins and Vespers in the Canonical hours.
