Covid Postponement

St. Mary’s on Paca Street looks forward to welcoming guests and visitors in 2021, but 2020 has already affected the coming year. The January 9, 2021, Mass commemorating St. Elizabeth Ann Seton’s 200 Anniversary of Death has been postponed to a tentative mid-June 2021 date.  Details will follow once we know where we are within this pandemic.

We wish all our Friends, Supporters, Pilgrims, and Guests a Happy and Healthy Holiday Season so that together we can arrive at a place in time in the near future when COVID-19 is properly consigned to history.

St. Mary’s Historic Site is a unique place, both in its history of the Catholic Church in the United States and in its contemporary spiritual ministry. Located at 600 North Paca Street, St. Mary’s Historic Site is home to two buildings on the National Register of Historic Places: the Mother Seton House and the Historic Seminary Chapel. The site is also home to St. Mary’s Spiritual Center.

Mother Seton House

In 1791, at the invitation of Bishop John Carroll, the Sulpician Fathers arrived in the City of Baltimore and settled on this very site to begin the first Roman Catholic Seminary in the United States. Bishop Carroll knew of the Sulpician Fathers’ unique ministry of priestly formation from their ministry in France, and thus he invited them to come to his young diocese in the United States to do their ministry of priestly formation in this new land. The seminary, founded in 1791, was initially located in a building on the southeast corner of the property known as the One Mile Tavern. With the help of Bishop John Carroll and others, the Sulpicians were able to purchase additional property adjoining the One Mile Tavern and build St. Mary’s College and Seminary.

The only remaining structure of the seminary is the Historic Chapel. The building of the chapel began in 1806 and was completed and dedicated in 1808. The chapel was designed by the renowned French architect Maximilian Godefroy, who himself was a friend of Benjamin Latrobe, often referred to as the Father of American Architecture. The chapel attracts architectural students as well as pilgrims to the site.

The other historic building located on the site is the of home of Elizabeth Ann Bayley Seton. In 1975, Mother Seton, as she is commonly known, became the first U.S.-born canonized saint within the Catholic Church. Mother Seton, a wife, mother, widow, convert, educator, and finally saint, offers a wonderful example of all that we can be with the grace of God. Mother Seton arrived at the Paca Street home the day of the dedication of the Seminary Chapel in 1808. She came to Baltimore at the invitation of Sulpician Father Louis W. DuBourg, who was then president of St. Mary’s College & Seminary. She, her three daughters, and several other girls called the Paca Street house their home for only one year, 1808 to 1809. During that year, she befriended a student at St. Mary’s named Samuel Cooper. Mr. Cooper, a man of resources, gave Elizabeth Bayley Seton eight thousand dollars with which she purchased St. Joseph’s Valley in Emmitsburg, Maryland.

In 1809 she left her humble roots on Paca Street and began her 3-day journey to Emmitsburg. While in Emmitsburg, once again under the tutelage of the Sulpician Fathers, Mother Seton began her new ministry of Catholic education. It was Sulpician Father Dubois who welcomed her to Emmitsburg and helped her become established in her new home. Her relocation to Emmitsburg was eased by the fact that the Sulpician Fathers were present as neighbors to her at Mount St. Mary’s College and Seminary, founded by the Sulpician Fathers in 1808. This institution and the presence of the Sulpician Fathers, gave great support and solace to the young widow and her dreams of founding a religious congregation and establishing a school for girls in Emmitsburg.

Good Morning Friends of Saint Mary's Paca Street: Today we celebrate the arrival of Stephen Badin to our historic site. In 1792, St. Mary’s received a new student in the person of Stephen Badin who, a year after his arrival to Baltimore, was to have the distinction of being the first Catholic priest ordained in the United States. In 1795 Fr. Badin went to Kentucky and except for a visit to France for the years 1820-1828, he remained in the West during the remainder of his life.
