Shortly after the death of Pope Francis, I am reminded of his willingness to apologize for bringing the teachings of Roman Catholicism to the Indigenous of Canada.
The residential school system, although inappropriate in its linguistic approach, was a noble attempt to bring Roman Catholicism to the Indigenous. The fault here is not on the concept of residential schools themselves, but their attempt to linguistically assimilate the Indigenous: they often resorted to physical abuse in order to do so.
The missionary can only succeed if they speak to the Indians using their native language (rather than forcing them to speak English/French). If the residential schools were offered to Indigenous in their native tongue, they would have been a success.
In demonstrating to the Indigenous the superiority of our faith, we can only assimilate them in accordance with their mutual consent. We must not punish them for using their native language, for these people called this land home before we colonized it.
This was the problem with the residential school system in Canada. It was not because of Catholicism that the Indigenous suffered, but because the deployment of the residential school system forcefully removed the Indian from their native culture.
We should have residential schools in Canada, but if they are for the Indigenous, then they must be used to develop their culture within a Roman Catholic context.
