"[1] The parish was founded in 1960 due to overcrowding at St. Mary of the Assumption Church in Dedham.

[3] By the 1930s St. Mary's was one of the biggest parishes in the Archdiocese with over 6,000 parishioners and 1,300 students in Sunday School.

[8] The first pastor of St. Susana's, Father Michael Durant, lived at St. Mary's while his church was being constructed.

[11] The parish garnered the attention of national media during Advent 2018 when the Nativity scene outside of the church showed the Baby Jesus in a cage and the three wise men separated from the others by a fence labeled "deportation."

The scene was a statement on the Trump administration family separation policy and on the condition of refugees more generally.
