Trinity Sunday



A hymn to the Blessed Trinity from the old Carmelite Rite:

O Pater sancte, mitis atque pie,
O Iesu Christe, Fili venerande,
Paraclitusque Spiritus o alme,
Deus æterne!

Trinitas sancta, Unitasque firma,
Deitas, vera, bonitas immensa,
Lux Angelorum, salus orphanorum,
Spesque cunctorum!

Serviunt tibi cuncta, quæ creasti:
Te tuæ cunctæ laudant creaturæ:
Nos quoque tibi psallimus devoti,
Tu nos exaudi.

Gloria tibi, omnipotens Deus,
Trinus et unus, magnus et excelsus;
Te decet hymnus, honor, laus et decus
Nunc, et in ævum.
Amen.


The 1962 rite contains the last gasp of the old Quicumque Vult, the Athanasian Creed. It used to be part of the liturgy fairly regularly but by 1962 only made an appearance at Prime on Trinity Sunday. In the Pauline Rite it's not to be found at all. You can find it at several sites on the web, including this one.
