Introduction

This hymn of devotion to the Blessed Trinity is the official prayer of the Order of the Blessed Trinity, otherwise known as the Trinitarians. This devotion has been recited by them and their affiliates for centuries in praise of the Trinity.

In nomine Patris et Filii et Spiritus Sancti. Amen. 

V. Domine, labia mea aperies. 

R. Et os meum annuntiabit laudem tuam.

V. Deus in adiutorium meum intende. 

R. Domine, ad adiuvandum me festina.

V. Gloria Patri et Filio et Spiritui Sancto, 

R. Sicut erat in principio, et nunc, et semper, et in saecula saeculorum. Amen.
