The Ladies' Book of Etiquette, and Manual of Politeness

If there is another person in the same pew with yourself, who, more familiar with the service, hands you the book, or points out the place, acknowledge the civility by a silent bow; it is not necessary to speak. In your own pew, extend this courtesy to a stranger who may come in beside you, and even if it is a gentleman you may, with perfect propriety, hand him a book, or, if there is but one, offer him a share of your own. Endeavor always to be in your seat before the service commences, and after it is over do not hurry away, and, above all, do not begin your preparations for departure, by shutting up your book, or putting on any article of dress you have removed, before the benediction. If you are invited to accompany a friend to church, be sure you are ready in good season, that you may not keep her waiting when she calls, or cause her to lose any part of the service by detaining her at your house. If you invite a friend to take a seat in your pew, call for her early, give her the most comfortable place, and be sure she has a prayer and hymn-book. If you are invited to stand as god-mother to a friend's child, be at the house of the parents in season to accompany the family to church, and send, the day before, the gift you design for the babe. A silver cup is the usual present, with your little namesake's initials, or full name, engraved upon it.
