100 Acts of Mercy

The Sisters of Mercy were famously nicknamed the “walking nuns” because, unlike most 19th-century religious orders that stayed secluded behind cloister walls, their founder Catherine McAuley insisted that “the streets will be our cloister” to actively serve the poor, sick, and uneducated. For our Centennial, we’re inviting you to actively serve others by completing 100 acts of mercy in 100 days.

This event honors the Sisters of Mercy and all they have done and continue to do. By participating, you are joining countless members and friends of Mercyhurst University who are channeling the spirit of the Sisters of Mercy and the charism of Catherine McAuley.

The event will last for the 100 days following the Centennial celebration on Sept. 20. Submissions will be accepted through Dec. 29, 2026.

You can upload pictures, videos, and stories via a link that will be available Sept. 20.

The sky is the limit! The Sisters of Mercy would encourage you to think about the Corporal and Spiritual Works of Mercy, acts of kindness and service, and the Mercy Critical Concerns of women, immigration, earth, nonviolence, and anti-racism.
