DENVER — Denver’s Catholic archdiocese is campaigning for sainthood for a former slave known for her service to neighbors.

A Mass was held Sunday at the Cathedral Basilica of the Immaculate Conception where Julia Greeley was proclaimed a Servant of God.

Greeley was born into slavery in Missouri in the mid-1800s and came to Colorado around 1880. She worked as the housekeeper for the first territorial governor of Colorado, William Gilpin, and was known for her charity work.

Greeley is one of four people that U.S. bishops voted to allow to be investigated for possible sainthood at their fall meeting.

The first step in the process involves gathering testimony and documentation about her life. A report will be sent to the Vatican, which will decide whether to proceed.
