The Africans in our congregation in Spain were allowed to keep a lot of their beliefs and prejudices especially those against women. Wives were completely in subjection to their husbands and could barely speak unless what they wanted to say was pre approved by hubby.
Our book servant was from Nigeria and he wouldn't distribute literature to single sisters we had to get a married sister or brother to ask for what we wanted. That annoyed me but when I asked an elder to ask him to let me get my own literature I was asked to do it his way.
Studies with the African refugees was done with the society's children's colouring books. There was one or 2 lines per page and even tho we tried to teach them God's name was Jehovah they never grasped God and Jesus weren't the same and we were advised to just let them call God Jesus.
It was always a pleasant study (it rarely rains or is cold in Fuerteventura) as we were banned by the Red Cross housing where they stayed so we did it under trees in the local park. (No appointment necessary) A very easy few hours because often as one study finished someone else would come in to the park to ask if we could "study" with them too.
