Madeleine Harris, Servant Year Ministry Resident

mharris@saintmarksphiladelphia.org

Madeleine Harris, originally from North Carolina, graduated from Eastern University in 2017 with a BA in Philosophy. After graduating she spent a summer living in community with the Sisters of the Love of the God, an order of Anglican women religious in Oxford, England. While there, she found great freedom and opportunity in the structure of the Daily Office, including the daily celebration of the Eucharist, which created a thirst in her to find a way to incorporate monastic values into ordinary life. During her time as a Ministry Resident at Saint Mark’s, she is thrilled to live as a member of a community dedicated to and resting upon prayer. She considers herself immensely blessed to have been a part of the shared life of Saint Mark’s for the last three years, and is excited for the opportunities of the year ahead. In her spare time Madeleine enjoys shredding on the ukulele and reading medieval women mystics.

Roses Laughlin, Servant Year Ministry Resident

rlaughlin@saintmarksphiladelphia.org

Roses Laughlin has joined Saint Mark’s as the Ministry Resident for Outreach for the remainder of the year. A native of the Philadelphia area, she returns after spending three years studying at the University of Pittsburgh. After graduating last spring with a degree in Linguistics, Roses walked the Camino de Santiago across Northern Spain with a group of young adults. Her academic interests outside of Linguistics lie mainly in studies of Theology, Spirituality, and Literature. Her love of language plays an integral role in her love of liturgy, and vice versa, and she is thankful for the opportunity to live in a setting fully immersed in daily prayer and the celebration of Eucharist. She believes these things to be transformative and good for the world in which we live. During her time as a Ministry Resident at Saint Marks, she looks forward to engaging more intimately with the community, deepening her practice of prayer, and experiencing a life of daily service alongside her fellow staff members.

Gabi was born and raised in London, U.K. to Brazilian parents. She studied Theology and Biblical Studies at the University of St Andrews, Scotland. Her final year thesis was on mystical spiritual teachings, through the focus of the classical Catholic contemplative tradition of Saint John of the Cross, Thomas Merton and in first personal testimonials from a group of Carmelite Sisters in Scotland. She then went on to complete her Postgraduate Diploma in Education, specializing in Religious, Moral and Philosophical Studies. Last year, she served with Newark Acts as a kitchen manager/chef at the Hoboken Shelter. She never thought she could say with confidence that she can cook a nutritious meal for over 100 grown adults in under 2 hours… Besides cooking, you will most likely find Gabi drinking tea and reading, taking photographs, singing, playing her guitar and enjoying the outdoors.
