October 27, 1922 – March 12, 2025

Sister Jane Mast died early in the morning of March 12 at the age of 102.

She was born on October 27, 1922, in Hayward, California, the daughter of John Mast and Louise Rose Walde. She entered the Sisters of the Holy Family from St. Anne’s Church in Union City, CA, in 1944, and celebrated her 80th Jubilee with us in 2024!

Sister Jane started out at our Motherhouse in San Francisco, serving in parishes nearby until 1949 when she moved to our new Motherhouse in Fremont, where she went out to parishes near there until 1954. From then until 1964 she served in parishes in Marin and Alameda counties, until she went to Los Angeles, then San Jose, then the Bay Area again and Las Vegas, returning to Los Angeles in 1987, where she remained until 2008.

During her time in the Los Angeles Archdiocese, she encountered the Catholic Charismatic Movement which had a profound effect on her life and spirituality; her life since then has been filled with “Alleluias”!

In addition to prayer and spirituality, Sister Jane is known for her love for history; she was a consultant on the founding mission of the Sisters of the Holy Family when the order was revising its constitutions in the 1970s and ‘80s. In 2008 she returned to the Holy Family Motherhouse in Fremont, where she has been engaged in a ministry of prayer.

Sister Jane’s funeral Mass will be celebrated on Friday, March 28, at 1:30 pm in the Sisters’ Oratory. Burial will take place in the Holy Family Sisters’ section of Holy Cross Cemetery in Colma on March 31 at 11:00 am.
