I am from Panama where there are isolated tribes in the middle of an impenetrable.jungle and yes in my country it is illegal to attempt.to.contact some of these tribes. There are some who somewhat of a contact is allowed and I remember the Archbishop for that region some years ago was doing a lot.of great work.for them i.e. helping with access to medical care for sick.people, helping them with issues of.deforestation, help.with problems with the Colombian guerrilla, provide food for children, creating comedors to feed them, etc. But he never directly went into their land. He did a lot and he was very loved between them but besides him I don’t think there was any evangelization efforts from the church itself (and I wonder if the Church itself had any intentions as the Church there has a particular view based on the history) though there is also a possibility that in our case it has to do with the fact that the area is extremely dangerous. In fact, after he was removed, I think the new Archbishop didn’t interact with them at all. I know they were quite angry when that archbishop was removed. The ones who are more isolated the prohibitions come.from.them being in impenetrable areas (only way to see them is through helicopter) and contact is seen as disruptive to them, nature, their environment and their territory so the country wants to protect their land from.any external influence and basically let them be, and as mentioned before to prevent them from contracting diseases.
Sincerely, I am not much of a believer that we should “befriend them and show we mean no harm” or send people to.their.land to try to covert them directly. That is not.a good strategy. The native people of latinoamerica have suffered a lot, and I mean a lot because of our current civilization (and past civilization) wanting to befriend them and change their lives. What it has been done to them is cruel and inhumane and they deserve respect. Overcome diseases, that is not possible. Millions have died already because Europeans, Americans, French came in bringing all these diseases they didn’t even exist on the America’. Why put them again through another death path? They have suffered enough to be put through that misery again. Even most priest down there agree that intervention in their land is inhumane given all that has happened. The right way to approach them is the way the previous Archbishop was doing it: Providing help to.their problems and basic.needs and listen to their problems without intervening into.their land, and let them by their own will come to the church. Many of the native people in Panama turned to the catholic church just because the way this man was caring, fighting for their rights and helping the tribes. Try to go in and convert them was exactly what was done and proved to be not a good idea. Why it should be a good idea now?
