The millenial door thrown open or, The mysteries of the latter day glory unfolded, in a discourse, delivered at East-Windsor, state of Connecticut, July Fourth, 1799. The twenty-third year of the declaration of the independence of the United States: in which event was laid the corner stone of the national temple, under whose auspices all worshippers of God are allowed full indulgence: and from which springs the temple of the living God, into whose bosom the nations of the earth are to bring their glory and their honor. / By David Austin, Junr. citizen of the world.
