The mystery of the blessed Trinity, which was taught us by the mission of the Son of God into this world, and by the promise of the speedy sending of the holy Spirit, is announced to men by these solemn words, uttered by Jesus just before His ascension into heaven.

He had said: “He that shall believe, and shall be baptized, shall be saved”; but He adds, that Baptism is to be given in the name of the Father, and of the Son, and of the Holy Ghost.

Henceforward man must not only confess the unity of God, by abjuring a plurality of gods, but he must, also, adore a Trinity of Persons in Unity of Essence.

The great secret of heaven is now published through the whole world.

But, whilst humbly confessing the God whom we have been taught to know as He is in Himself, we must, likewise, pay a tribute of eternal gratitude to the ever glorious Trinity.

Not only has It vouchsafed to impress Its divine image on our soul, by making her to Its own likeness; but, in the supernatural order, It has taken possession of our being, and raised it to an incalculable pitch of greatness.

The Father has adopted us in His Son become Incarnate; the Word illumines our minds with His light; the Holy Ghost has chosen us for His dwelling: and this it is that is expressed by the form of holy Baptism.

By those words pronounced over us, together with the pouring out of the water, the whole Trinity took possession of Its creature.

We call this sublime marvel to mind as often as we invoke the three divine Persons, making upon ourselves, at the same time, the sign of the cross.

When our mortal remains are carried into the house of God, there to receive the last blessings and farewell of the Church on earth, the priest will beseech the Lord “not to enter into judgment with His servant”;

in order to draw down the divine mercy upon this Christian, who has gone to his eternity, he will say to the sovereign Judge that this member of the human family “was marked, whilst in this life, with the sign of the holy Trinity.”

Let us respect this divine impress which we bear upon us. It is to be eternal; hell itself will not be able to blot it out.

Let it, then, be our hope, our dearest title; and let us live for the glory of the Father, of the Son, and of the Holy Ghost. Amen!
