"From "The Sabbath in Puritan New England"
For many years after the settlement of New England the Puritans, even in outwardly tranquil times, went armed to meeting; and to sanctify the Sunday gun-loading they were expressly forbidden to fire off their charges at any object on that day save an Indian or a wolf, their two "greatest inconveniencies."

"In 1640 it was ordered in Massachusetts that in every township the attendants at church should carry a "competent number of peeces, fixed and compleat with powder and shot and swords every Lords-day to the meeting-house;" one armed man from each household was then thought advisable and necessary for public safety. In 1642 six men with muskets and powder and shot were thought sufficient for protection for each church. In Connecticut similar mandates were issued, and as the orders were neglected "by divers persones," a law was passed in 1643 that each offender should forfeit twelve pence for each offence. In 1644 a fourth part of the "trayned hand" was obliged to come armed each Sabbath, and the sentinels were ordered to keep their matches constantly lighted for use in their match-locks. They were also commanded to wear armor, which consisted of "coats basted with cotton-wool, and thus made defensive against Indian arrows." In 1650 so much dread and fear were felt of Sunday attacks from the red men that the Sabbath-Day guard was doubled in number. In 1692, the Connecticut Legislature ordered one fifth of the soldiers in each town to come armed to each meeting, and that nowhere should be present as a guard at time of public worship fewer than eight soldiers and a sergeant."

"In Concord, New Hampshire, the men, who all came armed to meeting, stacked their muskets around a post in the middle of the church, while the honored pastor, who was a good shot and owned the best gun in the settlement, preached with his treasured weapon in the pulpit by his side, ready from his post of vantage to blaze away at any red man whom he saw sneaking without, or to lead, if necessary, his congregation to battle. The church in York, Maine, until the year 1746, felt it necessary to retain the custom of carrying arms to the meeting-house, so plentiful and so aggressive were Maine Indians.
Not only in the time of Indian wars were armed men seen in the meeting-house, but on June 17, 1775, the Provincial Congress recommended that the men "within twenty miles of the sea-coast carry their arms and ammunition with them to meeting on the Sabbath and other days when they meet for public worship." And on many a Sabbath and Lecture Day, during the years of war that followed, were proved the wisdom and foresight of that suggestion.
The men in those old days of the seventeenth century, when in constant dread of attacks by Indians, always rose when the services were ended and left the house before the women and children, thus making sure the safe exit of the latter. This custom prevailed from habit until a late date in many churches in New England, all the men, after the benediction and the exit of the parson, walking out in advance of the women. So also the custom of the men always sitting at the "head" or door of the pew arose from the early necessity of their always being ready to seize their arms and rush unobstructed to fight."
