Inno e Marcia Pontificale - The Papal Anthem

This is the current anthem of the Vatican City State, voiced in latin.
It was first played in 1950 under request of His Holiness Pope Pius XII, then known simply as "The Pontifical March".
It is mainly without the vocals, and has an alternate set of lyrics in italian, which I'll try to find later.
The latin part has the V instead of U because my font is all-caps, and the capital version of U in latin is V.
PLEASE NOTICE US, PONTIFF!

Lyrics:

O felix Roma, O felix Roma nobilis.
O felix Roma, Roma felix, Roma nobilis.
Sedes es Petri, qui Christi vicem gerit,
Sedes es Petri, qui apostolus est pacis.

Pontifex tecum erimus omnes nos
Pontifex es magister qui tuos confirmas fratres.
Pontifex tecum erimus omnes nos
Pontifex es magister qui tuos confirmas fratres.

Pontifex fundamentum ac robur nostrum,
Hominumque piscator pastor es gregis ligans terram et coelum.

Petre, tu es Christi es Vicarius super terram,
Rupes inter fluctus, tu es pharus ac veritas.
Tu Christi es caritas, tu es unitatis custos,
Promptus libertatis defensor; in te auctoritas.

Petre, tu es Christi es Vicarius super terram,
Rupes inter fluctus, tu es pharus ac veritas.
Tu Christi es caritas, tu es unitatis custos,
Promptus libertatis defensor; in te auctoritas.

O Roma nobilis
O Roma felix
Roma nobilis
