After Pope Francis issued his historic apology for the horrors of residential schools on Tuesday, a voice could be heard in the crowd calling for him to repudiate the Doctrine of Discovery.

That voice was Judy Wilson, chief of Neskonlith Indian Band and the secretary-treasurer of the Union of B.C. Indian Chiefs. The doctrine she was referring to is a more than 500-year-old pronouncement from the Catholic Church that gave colonial powers free rein to invade any land not yet "discovered" by Christians.

The Doctrine of Discovery originated in the form of papal bulls, edicts issued by the Catholic Church in the 15th century to empower Portugal and Spain to colonize, plunder and enslave West Africa and the Americas. Other colonial powers soon followed suit, and the doctrine became the basis for slavery and European claims over Indigenous land and people.

Wilson says we're still feeling the effects of that doctrine today, in the form of residential school trauma, the Indian Act, the Sixties Scoop, the reserve system, the clean water crisis in Indigenous communities and more.

She is one of many Indigenous advocates calling on the Pope to use his visit to renounce the doctrine. Here is part of her conversation with As It Happens guest host Helen Mann.

I still haven't heard anything about repudiating the Doctrine of Discovery, which is where a lot of the genocidal legislation [and] policy — you know, the Indian Act, the residential schools, the creation of the reserves — all stem from.

The Doctrine of Discovery all occurred, you know, when Spain and Portugal, they had those papal bulls that gave those countries [the right] to conquer.

Then England followed suit after them, and they came over to our countries and said that the land was vacant and under terra nullius and that, you know, our people were savages, so that our land and resources and our people were open to do [with] as they wish — which was erasure, assimilation and eradication.

Fast-track that to today under the genocidal legislation the colonial governments came up with — you know, the Indian Act and all the different legislation that dispossessed us from our lands, our waters and our language and our culture.

First of all, the accountability is so huge in this. So repudiation is the accountability of what happened to our people.

Even if [we have] the bare minimum of apology over residential schools … it doesn't go far enough of changing those legislation and policies, and changing the paradigm between state, government and our people and the Crown, and all the parties involved. So we have to have that to be able to have the truth before reconciliation, so we can get on with the work.

I'm a chief, but we don't hold title to our reserve lands. I'm still a ward of the government…. So we want our land back so that we can provide for ourselves, we can stand up our own law…. because that's so important to be able to take care of ourselves the way we did. And right now, we're just managing in poverty from programs and services, and stuck on small reservations.

That's not reconciliation. We need to find a better path through that. And every nation will be different according to ... where the nation is on these issues. But the repudiation of [the] Doctrine of Discovery is so fundamental to that.

Yeah, I heard that, too. I was right there and I heard it directly myself that, you know, he was saying again in different words, "those Christians," "those people," "those that did harm to Indigenous people." And he wasn't acknowledging and being accountable for the church's role in running those residential school institutions.

I heard he couldn't even say "sexual abuses." And there are many sexual abuses that happened to our children, and many died at the hands of those church-run institutions.

He could have gave a stronger mandate to the [Canadian] bishops and the archbishops and to the localized groups to be able to return many of our cultural items, our artifacts, our belongings that were wrongfully taken from us. And also saying we need to open our archives and our data to be able to provide that information back to the nations that, rightfully so, should be able to have them, as the nations are putting together the information regarding those residential schools and what happened to their children.

It's so important to at least know what happened to those children. I've been talking to some survivors that had whole families that didn't come home. Not just one sibling. Whole families. Like, you know, maybe out of six children, five didn't come home. Like, how could that happen?

There was an important film I saw the other day. It was The Doctrine of Recovery that talked about the Doctrine of Discovery and the repudiation by [three] beautiful tribal women across North America. And it has an important message … so I'm hoping people will see that so that they can get the information, because there's really not a lot of information out there when people are struggling to understand these issues.

For the next few days I'm going to continue to do what I need to do. And while [I was] … saying out loud, "Repudiate the Doctrine of Discovery and renounce the papal bulls and genocide," [I saw] a person here that did that, too.

And I just smiled because I thought, you know, some people are listening. Some people are getting it right. So I was happy to see that. So that kind of got me kind of hopeful today.
