Monastic and Mendicant Catholic Religious Orders - Gregorian Chant.

I did not make this video for deep explanatory or instructional purposes, but as a general overview of these religious orders. I have included only the most well known and popular orders, with the Latin name and abbreviation as well as the common English name. The pictures are a collection of Monastic and Mendicant monks and friars, and do not chronologically coincide with the slides. The Chant is 'Laetetur Cor':

Laetetur cor quaerentium Dominum.
Quaerite Dominum et confirmamini;
quaerite faciem eius semper.
Confitemini Domino et invocate nomen eius,
annuntiate inter gentes opera eius.
Laetetur cor quaerentium Dominum.
Quaerite Dominum et confirmamini;
quaerite faciem eius semper.

Let the heart of them rejoice that seek the Lord.
Seek ye the Lord, and be strengthened:
seek his face evermore.
Give glory to the Lord, and call upon his name:
declare his deeds among the Gentiles.
Let the heart of them rejoice that seek the Lord.
Seek ye the Lord, and be strengthened:
seek his face evermore.
