The phrase refers to the presence and distribution of the Book of Mormon, a religious text of the Latter Day Saint movement, within the Boston metropolitan area. This includes the availability of the text itself, the activities of missionaries from The Church of Jesus Christ of Latter-day Saints, and the presence of congregations adhering to its teachings in that region. For instance, one may encounter missionaries offering copies of the scripture on the streets of Boston or find organized groups studying and discussing its contents in local meetinghouses.
Its significance lies in representing the presence and outreach of the Latter Day Saint faith in a major urban center. The circulation of the scripture enables individuals to explore its tenets and potentially become members of the Church. Furthermore, the historical context includes the ongoing efforts of the Church to establish and maintain a presence in diverse geographic locations, engaging with the local community and contributing to the religious landscape of Boston.
