All of this had to be before the establishment of the Church of Jesus Christ of Latter-day Saints upon the earth. These things took place in Europe before the discovery of America. After America was discovered liberty upon this land received an impetus which the old world could not give to it; and through the shedding of blood, the land was redeemed (the Lord has said it [D&C 101:80]) and freedom proclaimed in the constitution of the country, so that all peoples of the earth could find a place of refuge in America, the Land of Promise. When that was accomplished, the time had come for the bringing forth and establishing of the gospel of Jesus Christ upon the earth.
