Deceased

May 2, 1923 – December 4, 2025

Entered eternal life on December 4, 2025 at the age of 102 after 81 years of religious life. We commend Sister Aquinas to your prayers.

“Ability to be of service to others both within and outside my community has meant the most to me in my Dominican vocation,” wrote Sister Aquinas on the occasion of her silver jubilee. Years later at the age of seventy-five she remarked upon receiving the Edmund Frey Distinguished Service Award that she was not ready to retire. “Even if I retire, I will not be an idle person.” Her life before entering the congregation had prepared her well for a life of service.

Lucille Weber, born May 2, 1923, was the first daughter and fifth child of Jacob and Anna Weber, who operated a family farm near Kingsley in northern Michigan. She had nine brothers and one younger sister. From her mother she learned the skills of household management, including food preservation and the careful use of time and resources. In her father, she had a model for involvement in politics, education, and church activities. Large extended family gatherings were a Sunday routine; and during the Depression, the Weber family shared with neighbors and provided shelter to those in need.

Lucille’s education began at St. Mary’s School, Hannah, and was enriched through wide reading at home. After graduating from St. Mary’s High School in 1941, she worked for nearly three years in Detroit at Parke-Davis Pharmaceutical Co., where penicillin was the latest product. There she acquired business acumen.

Inspired by a young teacher in a rural school, Lucille made weekend visits to Marywood and entered as a postulant in 1944. At reception she received the name Sister Mary Aquinas – an exceptionally prophetic choice as she would later become Chancellor of Aquinas College. She earned her bachelor’s degree from Aquinas College and later pursued graduate studies at The Catholic University of America and Marquette University.

Her teaching ministry began at St. Stephen, Grand Rapids and continued at St. Mary, New Salem; St. Boniface, Bay City; and St. Alfred, Taylor, where she also served as principal. In 1963, Sister Aquinas returned to Grand Rapids as Directress of the House of Studies, where seventy young Sisters lived as they completed their education before being sent out on mission.

In 1966 Sister Aquinas was elected Prioress of the Dominican Congregation and was the first to discontinue the title “Mother.” During her six-year term, many other changes occurred: adoption of the official breviary, gradual modernization of religious dress, the introduction of preference sheets for ministry placement, freer association with lay people, and more flexible daily schedules.

When her term was completed in 1972, Sister Aquinas attended the University of Michigan, earning a master’s degree in Sociology with a concentration on urban studies. Upon returning, she became the first director of the Eastown Project, an initiative founded by Aquinas College to address urban blight in the surrounding neighborhood. The Eastown Community Association—later recognized as the first of its kind in the city—was formed under her leadership. Sister Aquinas made frequent trips to City Hall to advocate for better police protection, lighting, street repairs, and demolition of abandoned buildings. When the college transitioned leadership of Eastown to the residents, she remained a member of the Grand Rapids Housing Authority until 1979.

In 1976 Sister Aquinas was elected treasurer of the Marywood Congregation, a position she held for four years. In 1980, she began three years as Directress of Aquinas Emeritus College, a program of non-credit courses for older adults. Then President Norbert Hruby persuaded her to become Vice-President for Development at Aquinas; her title was eventually changed to Chancellor – Special Assistant to the President. She continued serving the development department as fund-raiser – or friend-raiser – as she preferred to call it.

Sister Aquinas was also a prominent leader in public affairs. She was the first woman elected to the board of the Old Kent Financial Corporation and served on boards of the Salvation Army, YMCA, St. John’s Home, Gleaners, Porter Hills, and Hospice of Greater Grand Rapids. Her numerous awards include the Notre Dame Award for distinguished leadership in Christian ideals of justice and moral responsibility; the Tree of Life Award (highest honor of the Jewish National Fund) for promoting Jewish-Catholic relations; the first Aquinas Reflection Award; and the Legacy Award from the Greater Grand Rapids Women’s History Council. “It is my hope, “she once said, “that women may serve in positions anywhere with the same credibility, recognition, and compensation given to men.”

In her professional life Sister Aquinas was noted for vision, commitment, integrity, and trustworthiness. Despite extensive public recognition, she remained unassuming and simple in her tastes. She was faith-filled and attentive to daily Mass, meditation, and liturgy of the hours. She was a loyal friend and a frequent visitor to those who were sick or lonely and in need. Drawing on her early years on the family farm, she cultivated vegetables in the backyard of her home on Woodward Lane and ventured out to harvest from berry patches and orchards. Her hobbies and interests included reading, hiking, cooking, fishing, and travel.

She will be remembered for her strong, level-headed commitment to justice, her kindness to those in need, and her faithfulness to serving God above all as she lived her Dominican life most fully to the end.


Sr. Aquinas is survived by sisters-in-law, Barbara Weber and Mary Ellen Weber, many nieces and nephews, friends, and members of her Dominican Community.

As we honor Sister Aquinas Weber’s life and legacy. Please share a memory in our guest book.

“Her wisdom, her great talent for enlisting human resources, and her undying devotion to the educational commitment of her Order have given new life to all that she touches.”

The late Hugh AllenFormer Vice President of Development, Aquinas College

“For the past 50 years, I have referred to Sister Mary Aquinas Weber as my ‘favorite sister.’ She is and always will be my favorite sister, and ‘the other woman’ whom I have loved for a lifetime. In mutual respect and drive, we had a very clear agenda: what can ‘we’ do to improve the lives of all the people of Grand Rapids. I love and will continue to love My Sister - to whom I have never been able to say ‘NO’.”

Rabbi Albert LewisRabbi Emeritus Congregation Emanuel

“Sister Aquinas Weber lived the four characteristics of Dominican Life, “to pray, to study, to serve, to build community,” -- one might describe her as writing a full chapter of Dominican life through her ministries. Truly, any request coming from Sr. Aquinas came with an assurance that the work you were undertaking had merit. She could see what could be, the possibilities, then identify the people who could also see the light further down the road. Due to her vision and influence, you didn’t see many projects fail.”

Sister Teresa Houlihan, OPFormer Prioress (1980-1988) Dominican Sisters ~ Grand Rapids

“Sr. Aquinas loved God dearly and deeply, and ceaselessly gave her life energy to care of the common good, both in building relationships and serving others.”

Sister Carmelita Murphy, OPFormer Prioress (1988-1994) Dominican Sisters ~ Grand Rapids

“She always encouraged me to continue with my education… it was my honor to receive my diploma last this year from her on stage at graduation in May. We all know when Sr Aquinas asked you to do something for the Dominicans or Aquinas, we all know you couldn’t say no to Sr Aquinas. Whenever she called my answer was always yes, she had a great way with people and accomplished.”

John Lowery ‘24CEO of Applied Innovation and Chair of the Aquinas College Board of Trustees

“It is difficult to put into words of the enormous impact Sister has had on Aquinas, and me personally particularly when I became a Aquinas College Trustee. She was generous in her guidance and friendship as I began my three 3-yr term. And I will never forget her sharing her home canned peaches with me when I mentioned I missed my Mom’s canned peaches when she passed away! Always generous and concerned with others. Love you, Sister Aquinas!”

Karen L Palmore ‘89Former Vice President at UBS Financial Services and Trustee Emeritus of Aquinas College

“The College really benefited from her loyalty and reliability… She was aware of the real world and looked at things in a much more realistic way … She always did what needed to be done for the good of the College.”

The late Dr. Norbert HrubyFormer President, Aquinas College

“When I was a novice, I remember talking with Sister Aquinas(Prioress) and she offered encouragement: Always stay true to who you are. She then shared one of her favorite quotes Michah 6:8… “I do my best each day to Act Justly, Love Mercy, Walk Humbly With You/My God…””

Maribeth Holst, OPFormer Prioress (2000 - 2006) Dominican Sisters ~ Grand Rapids

“It is with great sadness that I received the news of the death of Sister Mary Aquinas Weber, OP. Sister Aquinas was a pillar not only of Aquinas College, but also of the larger West Michigan community. Though recognized and honored for her many accomplishments, her tireless efforts were expressed with true humility. Sister Aquinas paved the way for many other women through her example and leadership. The Dominican Sisters elected her as their youngest Prioress. During her tenure, she led the community through the renewal of religious life proposed in the implementation of the Second Vatican Council.
Sister Aquinas provided us with a sterling example of servant leadership, leading with confidence, authenticity and kindness. Her constant desire to serve those around her demonstrates the importance of sharing our blessings and talents with others. For almost twenty years, she faithfully served on the Diocesan Finance Council. In 2011, Pope Benedict XVI bestowed upon her the ecclesiastical honor of the Pro Ecclesia et Pontifice Cross, recognizing her distinguished service to the Church.

Most Reverend David J. WalkowiakBishop, Diocese of Grand Rapids

    Thank you for informing me about Sr. Aquinas’s passing. She was my teacher in college, and I learned so much from her. So happy she can now enjoy her reward with our loving Jesus.

  • Marilyn Drake says:

    My heart and prayers are with you all. I know we should be happy for Sister, but we will miss her.

  • Don Walsh says:

    In the formative years of the Eastown Community Association she was the silent partner from Aquinas College, always supportive, never intrusive. There would have been no ECA without her.

  • Marge Giesken says:

    Sister Mary Aquinas was a woman of great faith, and a profoundly deep and loving relationship with our Lord. Sister Aquinas, is the reason that I was allowed to enter the Dominican order. I asked her recently. Why did you allow me to enter the order? She looked at me with that wonderful little smile that she had and said.” I saw something in you.” that’s something was my deep love and relationship with the Lord. I will always be profoundly grateful for sister Aquinas mentoring of me of her, sharing her life, her faith her love of God with me. I know that she and God the Lord are having some wonderful conversations right now.

  • Sr. Aquinas encouraged, supported, and believed in me when I first entered the community. She has been a mentor and supporter all these years. She was a role model for me. Her love for Jesus was what inspired me daily. My first year there, I broke a rule ( when the bell rings at 9:00, we were to be silent and go to our room). My first week there, I saw a postulant crying as I was walking to my room, after 9:00. I knew I would not sleep that night, worried about her. So I talked to her. The next morning, I was called into the superior’s office. She let me know I broke the rule by talking to someone after 9:00. I told her,” When I saw her crying, I asked myself what would Jesus want me to do, and Jesus told me to talk to her.” She said to me, “So are you going to use Jesus when you get in trouble? ” I said, “I don’t know who else to use.” She smiled and said I could leave the room. Sr. Aquinas saw me and told me she heard what I did. That is when I told her what my Dad told me. “Don’t let them change who you are; they can sand off the edges, but if you have to change who you are, it is not a call from God.” She told me, “Dorothy, don’t you change, be the woman God has called you to be.” I remember telling her, “I will always follow the rules unless Love demands more.”She has supported me ever since.

    In 1968 my third year as a Dominican, I was in my second year at Aquinas College, living at the House of Studies. Sister Aquinas was our Prioress and contacted me. She said my Dad had called her told her that my Mom was very worried and discouraged about my twin brother, Mark, who was in the Army serving as a radio operator in the jungles of Vietnam. Dad asked her if I could go home for a visit. He thought that would really help my Mom. I recall that in the 60’s the news of the war was on the front pages of our newspapers every day in great detail, so it was very frightening. At that time the policy that it was three years before our first home visit so I had a year to go. Sister Aquinas told me there were Sisters going to Alpena that next weekend and I could go home to see my Mom, Dad and our 8 younger siblings. It was a wonderful visit. Dad said that my visit really helped Mom. My dad never forgot her kindness and neither did I. Late that next year Mark and his wife Georgi picked me up to go home. Sister Aquinas truly valued family.

    I first met Sr. Aquinas while working in Campus Ministry at Aquinas. She and Sr. Catherine Williams would attend Mass on Mondays and Wednesdays at Bukowski Chapel. She was amazing in how active she was in the life of the Aquinas community, and always had a smile for me.
