Faith/religion is a very personal thing. To the non-believer, most religions seem crazy, led by delusional, autocratic leaders, guided by seminal texts with often questionable content. I grew up in a church in part guided by the teachings of John Calvin, and attended Calvin College, a small college associated with the (Dutch) Christian Reformed Church. Having left that church and that religion more than half my life ago, it is tempting for me to enumerate all the ways it seemed to the non-Calvinist world (including me, now) insane, or at the very least misguided, focused on total depravity predestination and so on.
Growing up in a religion--I was required to go to church for services twice on Sunday, and my parents in the previous generation went three times, the middle service entirely in Dutch--and a descendant of the theologian Abraham Kuyper, I was steeped in religion, and part of the process of creating a religion seems to me staking out theological territory that delineates right religion from wrong religion. So in my religion all other religions were seen as lacking, including Mormonism, also known as the Church of Latter Day Saints. We were introduced to Joseph Smith in World Religion classes--to his visions, his "divine inspiration" to create a sort of competing religious text to the Bible, his divine decree to establish polygamy as God's Will--as a kind of fraud. Calvin was seen by my religious community as rational and devout and Smith--who was killed by an angry mob in 1844 at the young age of 38--as insane, but to others, atheists, both were and are seen as ludicrous, I suppose.
I say all that to acknowledge and respect what I take to be Noah Van Sciver's magnum opus, Joseph Smith and the Mormons, his most ambitious project, accomplished at more than 400 pages over decades. Van Sciver was led out of the Mormon religion by his mother, who divorced Van Sciver's Mormon father, so he spent his life wondering about Smith and whether Mormonism might have been the way to go for him. So it's personal, and detailed, and in it he tries to be objective, not commenting on the story he tells in graphic novel or biographical fashion, with lots of notes and an afterword.
To say the story is, for non-religious types, especially, a kind of slog is to understate the experience. Unless you are Mormon, you won't care to read the fine print of Mormon history. The art is among his best ever, but the story could have been accomplished in half the time to get at the essence of Smith's life and ideas. And his wife! This is by my count the fourth nineteenth-century book Van Sciver has illustrated and/or written: his book The Hypo, about Lincoln; a book about Johnny Appleseed; a book about the socialist politician Eugene Debs, and this book on Smith, and my collected impression is that these books are text-heavy, strange, focused on pretty wacky folks (sorry) on the whole. Compared to his humorous and/or touching books such as Saint Cole and Fante Bukowski, these historical books are deadly serious, completely without humor, and comparatively dull. But give Van Sciver credit for his ambition to come to terms with Smith and the religion in which he had been raised. I can see why others might five this five stars, as his masterpiece.
