I mean, I have read their five main books and it never really stated specifically.

im not rich enough to buy books. and what little i have i have to buy Used anyway. i dont even make enough to pay rent but i do make enough for gas so i do live in my car.

I know they’re not exactly the same thing. I googled it but didn’t understand Wiki.
I mean like someone being a Spiritualist and someone being a Spiritist.
I don’t mean like being a “spiritual” person. .as in religious.
A psychic I went to years ago said “I’m a Spiritualist…not a Spiritist.”

I’ve been researching this all day and cannot find the accurate differences between the two. Can someone please help? I need this information for a paper i’m writing.

Full Question:
What are the factors behind the growth of Pentecostalism and spiritism since the mid-20th Century? And what are the main differences between these religions and mainstream Catholicism and Protestantism?
