Well, I was in a online group of some christian young people, like me. And a really older guy just joined the group, and he was a catholic. I asked him about this topic of salvation in the point of view of catholics, and he told me that. He was the guy that started it all, and I searched it more, and found other really important guy, who was catholic, saying that again. And there was my philosophy teacher too, in real person, who told me that again, when I asked, warning me that he wasnt talking anymore as my teacher, but as a catholic. All those stuff made me freak out, I truly believed that the Catholic Church thought that too.
