Final answer:
Church membership in Puritan communities required spiritual conversion, leading to a membership decline. In response, the Puritans established the Halfway Covenant in 1662 to allow for a broader membership, causing controversy among conservative members.
Step-by-step explanation:
The practice of church membership among the Puritans was closely tied to the concept of religious conversion and attaining a state of being 'born again'. Initially, only those who had undergone a spiritual conversion could join the congregation and access its associated privileges, such as voting rights, a concept referenced by Proctor. This restrictive membership led to a decline in church membership, pushing the Boston Puritans to implement the Halfway Covenant in 1662, which allowed baptism and partial membership for the children of virtuous Christians who were not full church members.
This covenant, however, was met with controversy, signifying the beginning of a period of trials and conflicts within the New England colonies that included events like the Salem witch trials and political upheaval following the Glorious Revolution of 1688.
