Our series of mini-biographies we call "Catholic Lives" takes a look at the life and career of Orestes A. Brownson (1803-1876), a convert from New England whose spiritual journey took him from Evangelical revivalism to Unitarianism and the Transcendentalist Movement, before entering the Catholic Church in 1844. A thinker with a wrestling, combative style, Brownson became one of the premier Catholic thinkers in 19th century America, and someone whose political thought was grounded in the need for transcendent truths, above all the truth of the Catholic faith.
