Nobis Sancti Spiritus is the start of a verse from Horae Spiritus Sancti ("Hours of the Holy Spirit"), a medieval monastic office.
The full line of text in which these words appear is Nobis Sancti Spiritus gratia sit data, which is "May the grace of the Holy Spirit be given to us." (Nobis is "to us" and Sancti Spiritus is "of the Holy Spirit".)
The term "Holy Spirit" in Latin is "Spiritum Sanctum."
In nomine Patris et Filii et Spiritus Sancti
In nomine Patris, et filii, et spiritus sancti
"Spiritus"; root word for spirit, inspire, aspire, aspirate
The phrase is not Celtic, but Latin. It means 'In the name of the Father, and of the Son, and of the Holy Spirit.' It is "the sign of the cross" in Latin as used in the Roman Catholic Mass until vernacular (native) languages supplanted it during the period 1964-1970.
They're two different terms for the same thing. The word "spirit" comes from Latin spiritus; the word "ghost" comes from Old English gast, but the meanings of the two words are essentially identical (and in Old English the word gast was used as a direct translation of Latin spiritus in Christian writings).
The Boondock Saints prayer is spoken in Latin. It is a variation of the traditional prayer "In Nomine Patris, et Filii, et Spiritus Sancti" (In the name of the Father, the Son, and the Holy Spirit).
The Latin equivalent of the English statement 'Spirit never dies' is Spiritus nunquam moritur. In the word-by-word translation, the noun 'spiritus' means 'spirit'. The adverb 'nunquam' means 'never'. The verb 'moritur' means '[he/she/it] dies, does die, is dying'.(An alternative spelling for nunquam is numquam.)
The correct Latin phrase is in nomine Patris et Filii et Spiritus Sancti. The phrase means 'in the name of the Father and of the Son and of the Holy Spirit'. In the word-by-word translation, the preposition 'in' means 'in'. The noun 'nomine' means 'name'. The noun 'patris' means 'father'. The conjunction 'et' means 'and'. The noun 'filii' means 'son'. The noun 'spiritus' means 'spirit'. The adjective 'sancti' means 'holy, sacred'.
"Spiritus mundi" is a Latin term that translates to "spirit of the world" in English. It refers to a universal spiritual essence or energy that is believed to connect all living beings and elements of the world.
Spiritus surgens or spiritus ascendens(ascendens is commonly "rising" in Church Latin but means "climbing" in classical Latin).
The English translation of the Latin word "pons" is bridge or drawbridge. The pons is also a name for structure located on the brain stem and is named after the latin word.
