Sisters of Mercy

From the very first efforts of founder Catherine McAuley, the Sisters of Mercy have welcomed all people into their circle of care: rich and poor, powerful and powerless. 

Since its inception, Mercy Medical Center has been blessed by the service and dedication of the Sisters of Mercy. Over the years, the Sisters have served in a wide range of roles in support of the hospital and its mission. They are, without hesitation, the reason for Mercy’s past, present and future successes.

Inspiration for Nursing Awards

Mercy Medical Center promotes a culture of nursing and service excellence based on collaborative relationships, education and empowerment. Each year we recognize those nurses who demonstrate the values of Catherine McAuley in the spirit of Sisters who have served and inspired.

Nursing Leadership Award

In the spirit of Sister Mary Thomas Zinkand, RSM, 1916-2003

As President of Mercy Medical Center for 35 years, Sister Mary Thomas, RSM embodied the true spirit of the Mercy RN. Personal friend to the Mayor, Governor and Maryland’s U.S. Senators, she never forgot her nursing roots. Each night, she walked the hospital, going room by room to visit patients and making sure their needs were met. She was a humble and caring spirit who quietly modeled Mercy’s core values—dignity, hospitality, excellence, justice, stewardship, empowerment and prayer. Sister Thomas is fondly remembered as a charming and diminutive woman who was smaller than most, yet larger than life.

Compassionate Caregiver Award

In the spirit of Sister Mary Thecla Lancaster, RSM, 1921-1998

Sister Thecla, RSM was often described as the epitome of what a nun and nurse should be. Shy, humble and unassuming, she had an extraordinary way of connecting with the sick and dying.

Sister Thecla was a member of Mercy’s Pastoral Care department for over 20 years, and was known for making the selfless care of others her life’s work. Sister Thecla was quiet and compassionate…a constant comfort to Mercy’s patients and families. She lived the Spiritual Works of Mercy which challenge us to feed the hungry, give drink to the thirsty, visit the sick and give comfort to the afflicted. One of her most endearing qualities was her uncanny ability to “simply appear out of nowhere” when she was needed most.

Nurse Visionary Award

In the spirit of Sister Mary Damian Faller, RSM, 1912-2002

Nursing education, professional growth and continual learning were lifetime passions for Sister Damian, RSM. She helped establish the School of Nursing at the Community College of Baltimore in 1972. As an educator, she was described by the students whose lives she touched as firm, but fair. Sister Damian believed that care and education of the poor were at the heart of keeping God in the practice of medicine. At the age of 90, years after her career in nursing education ended, Sister Damian still clung fast to her conviction for young graduates that ongoing education was vital to the provision of modern, compassionate health care. Beloved and respected, she was also adored for her quick wit and ready smile.

Community Impact Award

In the spirit of Sister Helen Amos, RSM, President & CEO, 1992 to 1999

Sister Helen Amos, RSM, served as President and CEO before becoming the first Sister of Mercy to be named Executive Chair of the Board of Trustees in 1999.

Her indomitable spirit is living proof that she and her fellow Sisters of Mercy have always worked toward a brighter future…a future filled with hope and optimism that the challenges of poverty will be met with new and creative solutions. Sister Helen has received numerous local, State, national and international awards.

Nurse Hospitality Award

In the spirit of Sister Elizabeth Anne Corcoran, RSM, 1930-2018

Perhaps no one will ever personify the words, “the Sisters of Mercy welcome you,” as well as Sister Elizabeth Anne Corcoran, RSM. Her spirit of hospitality, irresistible friendliness, genuine attentiveness to the lives, concerns and interest of others, and her heart for the underserved call us to enlarge and enhance our efforts to lovingly care for and welcome our patients, their families, our neighbors and all who enter the doors of Mercy. As a long-time Mercy Nurse and the beloved “Queen of Hospitality,” as she was known in her later years, Sister Elizabeth Anne did her personal best to ensure all would be welcomed with a brand of hospitality worthy of the name, Mercy.

Continued Influence

The success behind Mercy Medical Center lies in the vision and spirit of the Sisters of Mercy. Patients and visitors will find tangible elements of the Sisters' influence throughout our Downtown Baltimore campus. These elements are symbolic representations of Mercy’s origins, our continued progress and the hope for the future that lies ahead.

The Mercy Cross

Paramount to the mission of the Sisters is the Mercy Cross. The original, designed by Catherine McAuley for the Sisters of Mercy, consisted of an ivory cross on top of an ebony cross, or a “cross upon a cross.” There was not a body on the cross and instead, Catherine challenged the Sisters to think symbolically, placing themselves on the cross with Jesus in his ultimate act of mercy for all humanity.

In the 1970s, the renewal taking place in religious life after the Second Vatican Council prompted the Sisters of Mercy to “modernize” the Mercy Cross and it has since become the official logo of the Sisters of Mercy throughout the world. The Mercy Cross can be found in many forms throughout the Mercy campus.

Laying the Foundation

The Sisters of Mercy are responsible for laying the spiritual foundation of God’s healing love in all people, and their ability to fulfill the needs of the surrounding community is evident in the physical landscape of the hospital, as well. Throughout Mercy’s history, the Sisters have been called to provide for those in need and on many occasions, this called for physical changes and new development.

Bricks from Washington University School of Medicine and College of Physicians and Surgeons are still highlighted in The Mary Catherine Bunting Center’s Skywalk Atrium. Both schools were forerunners of today’s University of Maryland School of Medicine. Mercy Medical Center is an outgrowth and clinical training hospital partner associated with all three of these medical schools.

The Skywalk Atrium also hosts the original trowel used by James Cardinal Gibbons in 1889 to lay the cornerstone of the new hospital built by the Sisters of Mercy. The trowel was used again by Lawrence Cardinal Shehan in 1963 for the new Tower building hospital. And finally, it would be used once more in 2010 by Sister Helen Amos and Mercy President and CEO Tom Mullen to place a brick from Dublin’s House of Mercy as part of The Mary Catherine Bunting Center. The House of Mercy was the original home of the Sisters of Mercy founded in 1827, and the brick used at the entrance of The Bunting Center stands as a testament to the Sisters’ lasting work and mission as the hospital looks ahead.

History Moving Forward

The introduction of The Mary Catherine Bunting Center in December 2010 was a significant moment in Mercy Medical Center’s history. The 20-story, $400 million facility represented Mercy’s investment in the people of the surrounding communities; once again planting roots in the City of Baltimore. However, not to be forgotten in the hope and success of the hospital’s bright future, is the origins and influence of the Sisters of Mercy.

To honor the Judeo-Christian heritage of the Sisters of Mercy, Jerusalem Limestone was chosen for the Chapel of Light, the Grand Staircase and the Main Information Desk on the Lobby level of The Mary Catherine Bunting Center.

This unique and beautiful stone was quarried and hand-carved in the Holy Land, near the town of Mitzpe Ramon in the Negev Desert in Southern Israel. Known as “Holy Stone,” Jerusalem Limestone is prized for its distinctive coloration, warm rich textures and tiny fossils which are visible throughout.

Since biblical times, Jerusalem Limestone has been revered for its unique attributes and was even used in many of the region’s most celebrated religious structures including churches, temples and the Western Wall. In fact, to preserve the unique character of the Holy City, this limestone is required by municipal code to be used on all buildings in Jerusalem.

In addition to the Jerusalem Limestone, The Mary Catherine Bunting Center honors the Irish heritage of the Sisters of Mercy through the extensive use of Connemara marble, also known as “Verde Connemara.” Recognized as the Emerald Isle’s national gemstone, Connemara marble is named for the West Galway region in Ireland where it is found. Its distinctive color serves as a reminder of the strong connection that the Sisters of Mercy have with their origins.

Embracing this special stone as symbolic of the Sisters of Mercy’s Irish heritage, the Connemara marble is used throughout The Mary Catherine Bunting Center, including the main elevator side panels, the lobby information desk and within the Mercy Cross in The Bunting Center’s cornerstone just outside the main entrance.

Story of Mercy

Visitors entering McAuley Plaza will find beautifully handcrafted artistic interpretations of Mercy’s past and windows into the hospital’s future as they gaze on the Mercy tapestries hanging in the McAuley Lobby. These seven exquisite tapestries tell the story of the Sisters of Mercy in Baltimore and their lasting influence on Mercy Medical Center, the City and the patients who are at the heart of all we do.

Mercy Tapestries Speak to the Heart of Mercy

Six original tapestries in Mercy’s collection tell the wonderful stories of Mercy Medical Center’s rich history – depicting the many facets of the spiritual and healing healthcare ministry the Sisters of Mercy have provided to the citizens of Baltimore for nearly 140 years. Each tapestry is emblazoned with a pledge to our patients, their families, our staff and all visitors who are welcomed through our doors. “Courtesy. Respect. Compassion.”

The collection’s newest tapestry conveys Mercy’s move into the future, and while it retains the same intricate detail of the original six, it has a slightly different style. Each “window” in the new tapestry lets us view the bonds shared between past and future generations. The sheltering leafy border surrounds the images and the teacup motif repeated along the bottom of the tapestry recalls the wish of Catherine McAuley, founder of the Sisters of Mercy, that “we greet one another with a comfortable cup of tea.” Since Catherine first uttered these words the teacup has become and enduring symbol of the hospitality of the Sisters of Mercy.

The Inspired Mercy Story

A one-of-a-kind, hand lettered and illuminated book of Mercy was created to record, explain and preserve the history and mission of the Sisters of Mercy in Baltimore. This extraordinary hand-bound book consists of oversized, beautifully designed and illustrated handmade pages that tell the hospital’s story, values and mission through quotations, calligraphy, watercolor, photography and collage. Filled with the inspiration of the Sisters, it is a point of particular pride this work of art was conceived by Sister Aine O’Connor, a Sister of Mercy who served as Assistant to the President for Mission at Mercy Medical Center for more than a decade.

Under her direction and with a spirited Story of Mercy committee, Sister Mary Jacque, a beloved Sister of Mercy, was the first artist to lend her skilled craftsmanship to the book. As chapters were added other Sisters took on the role of artist and creator. The first volume, now complete, culminated with renowned artist Jay Wolf Schlossberg-Cohen incorporating the handiwork of Mercy doctors, nurses, employees and administration into his artistic interpretation of the Mercy mission and values statements.

The Story of Mercy can be viewed and enjoyed by everyone in the Skywalk Atrium of The Mary Catherine Bunting Center. The Skywalk Atrium in The Bunting Center captures a snapshot of who and what Mercy Medical Center has been and remains to those we serve – a tower of hope for patients who need the healing care inspired by the Sisters of Mercy, a hospital committed to the medical education and teaching of future doctors and nurses and a medical center that is vested in the City of Baltimore and its citizens.
