I don’t have any links at my fingertips, but the generally accepted number from internet research on my part (for Africans of all Christian faiths) and from talking to people more knowledgeable of this subject is this: 25% of the African congregations are involved in plural marriages. In the Anglican tradition, such families are admonished to NOT take any new wives after they have converted. But still - there they remain in full force. Polygamous marriage is socially and culturally accepted (even revered) by Afrikans of all stripes…
I can speak from personal experience, at least on the Catholic side. I regularly do mission work in Tanzania. The area that I work in still has a substantial population of adherents to trational African religion. Polygamy is considered to be a barrier to the Church accepting a conversion.
A polygamous man is required to accept the first wife as his only wife. All other subsequent ‘wives’ are to be treated as honored sisters. The man is still required to provide for them, as he would any other member of his family. If that cannot be accepted, the man is not accepted as a catechumen.
There are no provisions for the man returning to the other ‘wives’ in any relationship other than as a sister. One failing to adhere to the Church’s teachings is subjected to admonishment by his fellow parishioners.
As such, most men in this state do not seek conversion.
I had a long conversation with the local Catholic bishop on that topic. I wondered why there were followers of the pagan religions in the 21st Century. The bishop kind of laughed. He explained that men are reluctant to convert to Islam ( also quite prevelant in Tanzania) because that would mean that they have to give up alcohol. And they are reluctant to convert to Christianity, because it would mean that they must be monogamous (and, in the case of Catholicism, cannot even divorce)
. There is no tradition of Agnosticism or Atheism in Tanzania, such people are looked upon with suspicion. So they remain in the pagan religions, simply for pragmatic reasons
The solution is to start with the children. If the Church has the better schools, the parents sent their children there. The pagan religionists generally have no issue with their children becoming Catholic (unlike the Muslims). So the Church is expanding by teaching the youth about the value of true marriage.
That is the Catholic view, but I have seen NO indication that the Anglicans or other Protestants have any more toleration for polygamy than the Catholic Church.
Yes, polygamy is part of the traditional African religions, and of local Islam, but it is something that I have seen all the Christian Churches rejecting, both at the leadership levels, and by those in the pews.
