John Leyser, Part 3 Chapter 13 of Holy Priesthood Volume 4.
Pages 165 to 173
From the time of Christ to the latter part of the 16th century, there were alternate efforts to either outlaw plural marriage or to promote it. Both the Popes and Protestant leaders took turns on both sides of the issue. With the aid of the Gutenburg printing press and the availability of the scriptures, many pamphlets and books began to be published supporting plural marriage. John Leyser came out with a great work in 1682 called Polygamy Triumphant, containing over 500 pages with nearly every supporting quote by leading scholars, ministers and even some Catholics. Its logic and common sense appealed to many people, even in other countries, but the general public accepted the subject more from curiosity than for an application in their lives. It was so well received that it became a sort of “source book” on the subject. But teaching people to live polygamy then, as now, had a similar effect of trying to sell someone a disease.
