Abbas Kadhim has a very enlightening post about how the various Muslim theologies and sects within them.
Please note that in theological discourse, the word “Sunni” is not helpful at all, because many schools of theology adhere to the four Sunni schools of jurisprudence. Indeed, members of one theological school can adhere to two, three, or all four of the Sunni schools. So let me run this by you again, since some people fail to distinguish between theology and jurisprudence.
I certainly didn’t fully understand the intricacys of the religion… heck, I barely have a hold on all the variants of Christians.
