This hymn was used for Vespers II for the Feasts of the Immaculate Conception and the Nativity of the Blessed Virgin Mary in the Paris Breviary(1736).
Unus bonorum fons, Deus, omnium,
Quam liberali fundis opes manu!
Non ante concessis Mariam
Quot properas cumulare donis!
Inter rigentes, ceu rosa, clauditur
Spinas, et acres vincit aculeos;
Præsens amaram virulenti
Gratia vim fruticis retundit.
Quantum pudicas inclita virgines
Præstat, remoto quæ dominam gradu
Sequuntur, et Regis parentem
Siderea comitantur aula!
Nec Angelorum par decus: hi Deo
Astant sedenti; fert hominem Deum
Maria, nomen dulce matris
Virgineo socians honori.
Regina mundi virgo, clientium
Tutela, mœstis perfugium reis,
Fer nostra Nato vota: tristem
Non patitur genitrix repulsam.
Sit Trinitati perpetuum decus,
Inflicta mundo quæ miserans mala,
In matre pignus nascituri
Non dubium dat habere Christi. Amen.
