A letter from a clergyman of the Church of England, to his parishioners : Concerning the great, but much neglected duty, of serving God by public prayers in their families, (so earnestly recommended by the Bishop of London, in his late letter to the clergy and people, &c.) as the best means of promoting piety and religion amongst us; and to the neglect of which, we may justly ascribe a large share of the prophaneness and immorality of the present age. To which is added, prayers for the use of families: and for a person in his more private retirements.
