The feast day of Our Lady of the Atonement is July 9, and is observed as an optional memorial in the Personal Ordinariate of the Chair of Saint Peter in the USA.

Lewis T. Wattson professed his vows as a Friar of the Atonement, taking the name Paul James Francis.

In the early 1900s, Wattson was a popular preacher in Episcopal churches, and Mother Lurana edited a small magazine called Rose Leaves from Our Lady’s Garden at Graymoor.

Begun by CICM Missionaries and consecrated in 1936, the Cathedral survived the Allied carpet bombing of the city towards the end of the Second World War.
