J.R.R Tolkien and C.S Lewis
One is a Catholic and the other backslided during his youth and became a protestant when he became 30.
One only became a protestant because one hang out often Tolkien who has strong religious influence since young.
One inspired the other to write The Chronicles of Narnia and the other inspired the other one to write Lord of the Rings.
Both became the greatest literary texts after 40 years.
More than the literary world, the books went on to penetrate the culture industry,into our movies.
It blows me away. Even their life stories blow me away.
