XVIIOn His Greatness

Before the mountains were brought forth, before the void itself was given a name, He is.

He does not grow old with the centuries. A thousand years in His sight are as the watch of a single night.

Holy, holy, holy. We do not summon Him. We are the ones who are summoned.

He who holds the stars in their courses bends down to the dust of a single soul.
Fiat Lux
A cathedral built in light: the hours, the chant, the meditations, the Holy Face, the wonders and the altar — walked chapter by chapter.
Enter the NaveQuaestiones
What newcomers ask most. The full readings live in the Codex inside the nave.
It is Latin for "God is great" — a confession of the greatness and omnipotence of God, and the heart of this site.
Yes. Gregorian chant is the traditional sacred music of the Roman Catholic Church, sung in Latin and named for Pope St. Gregory the Great.
Prayer, adoration, the Mass and Divine Office, meditation, study, and quiet rest. Many listen to pray, to focus, or to fall asleep in peace.
Latin plainchant in the tradition of the Church — the Kyrie, the Media Vita, hymns and litanies — sung as one unaccompanied line, in the austere manner of the medieval monasteries.
Yes. Every chant streams here and on the channel at no cost.
No. The chant was made to carry prayer, not to test scholarship. Listen first and let the sound do its work; the English stands beside the Latin whenever you want it.
Pope from 590 to 604 and a Doctor of the Church. Tradition credits him with gathering and ordering the chant; historians place the repertoire we now call Gregorian chiefly in the Frankish lands of the eighth and ninth centuries, where Roman chant was received and set down.
The chant is the Church's own liturgical song: one unaccompanied line in Latin. The anthems are modern orchestral and cinematic arrangements of sacred prayer, made for devotion rather than for the liturgy itself.
Traditionally at Compline, from Trinity Sunday until Advent. Through the rest of the year three other Marian antiphons take its place: Alma Redemptoris Mater, Ave Regina Caelorum, and Regina Caeli.
