The Great Litany
The Great Litany is said to be the first prayer composed in the English language (i.e. not an English translation from another language) for use in public worship. It is used in Anglican worship at various times and seasons, but is probably most frequently experienced during the season of Lent because of its distinctly penitential nature. In many churches, as here, it is chanted in procession around the perimeter of the worship space.
