The Mandaean Society of Massachusetts is the community body for Mandaeans in Worcester, where by the society's own account about 2,500 Mandaeans live, resettled from Iraq. Mandaeism is an ancient Gnostic religion that reveres John the Baptist and centres on masbuta, a repeated baptism in flowing water, which makes access to a river or a purpose built pool a practical concern for every congregation in the diaspora. The society publishes contact details but no premises address, so this entry records the city only.
