“ MILLENARIANS are those who believe, according to an ancient tradition in the church, grounded on some doubtful texts in the book of Revelation and other scriptures, that our Saviour shall reign a thousand years with the faithful upon earth after the first resurrection, before the full completion of final happiness; and their name, taken from the Latin word mille, a thousand,” has a direct allusion to the duration of this spiritual empire, which is styled the millennium. ”
