Yes, it sounds so ‘likely’ doesn’t it. Funny how one never finds any mention of this ever occurring with any other ‘heathen’ group; no stories of this happening to the Moors, to the tribes in Africa, or Asia, or the heathens in Europe. Only a snarky mention with no proof that that happened in South America.
I hate to say it, but to me it sounds like one of the more, um, ‘non-denominational’ Protestant sects which likes to go about ‘rebaptising’ South American Catholics has been poisoning the minds of those they seek for their group by lying about the Catholic Church. Look, every individual makes mistakes, there are enough examples in every single solitary event in human history where individuals made decisions that, in hindsight, were lousy. No need to make up things, unless your ‘brand’ of Christianity wouldn’t really stand up on its own without trying to ‘take down’ others. And sure, we’ll hear “Your church does that too”. There is no limit to the amount of ‘offense’ any given human being can feel, apparently.
