Which new England colony did not require all adults to attend church services

The New England colonists were predominantly Puritans who led strict religious lives. Laws in these colonies assumed that citizens who strayed away from conventional religious customs were a threat to civil order and should be punished for their nonconformity.

Roger Williams (1603 - 1683) was himself a puritan minister from Massachusetts Bay Colony. In his view, any civil authorities had no right to involve themselves in matter of faith. Banished from Massachusetts in 1635, he founded Rhode Island, the first colony with no established church and the first society in America to grant liberty of conscience to everyone.

Massachusetts Bay Colony was therefore the New England colony that did not require all adults to attend church service.
