Despite the difficulties in say certain parts of say for example, Africa, to get access to find the former spouse for an annulment case to documents, I haven’t heard from many Catholic Bishops from Africa saying they want Communion for the divorced and remarried because of such difficulties. .
I have some experience here.
As mentioned in other threads, I do regular mission work in a rural diocese in Tanzania, several weeks each year.
When I am there, I stay at the residence of the local bishop, and consider him to be a good friend.
That said, Africa is continent, not a country, and conditions vary widely.
But in East Africa, there is FAR less mobility than you would encounter in the US or even Europe. It is very unusual for a person to move far. And even then the family connections are stronger than you find in the US. A sister or brother would know where their sibling is living and how to contact them. In war torn areas, such as the DRC, northern Niger, or Sudan, all bets are off there.
What has traditionally been lacking are Tribunals. It is a matter of resources, these diocese are VERY poor. In the one that I go to, the average family income is about $500 per year. So the diocese itself as a whole has less income than a working class family in the US. So they are not exactly overflowing with spare JCDs to staff a tribunal.
There also hasn’t been as strong of a need, as divorce rates are generally lower. People will stay in bad marriages.
Where the big interest is with the Africa bishops is in regards to polygamy. When a polygamous family converts, the Church instructs the family that the man and the first wife are married, other wives are now sisters to them both. No negotiation. If there is an intent to remain polygamous, then the family is simply not received into the Church until such a point as the family agrees to abide by Church teachings. Some other Christian denominations will let the man choose which wife he remains married to, the Catholic Church does not.
Where this factors into the debate we are having is that the African bishops envision themselves having to explain why whites in the US and Europe can have sex with their second wife and still receive Holy Communion, while they cannot., or, in the case of the internal forum, why whites are allowed to choose which wife to be married to, and they are not.
