They'd do that Fur Shur.
However, a real quick reference at http://www.independent.co.uk/news/world/africa/the-big-question-whats-the-history-of-polygamy-and-how-serious-a-problem-is-it-in-africa-1858858.html refers us to the Parliament at Nurmburg that allowed 10 women per man.
Of course, the reference to the parliament at Nuremburg (1650) was a protestant parliament, not the Catholic Church.
Serious misremembering of facts.
