In the 200th year of American independence, President Gerald Ford officially established February as national Black History Month. The idea grew out of African-Americans’ longstanding heritage week timed with the February birth dates of the white emancipator Abraham Lincoln and the black abolitionist Frederick Douglass.

Douglass, the most powerful black orator and agitator during the campaign to end slavery, is the ideal topic for a religion feature this February. That’s due to a magisterial new biography that enjoys universal acclaim from critics, “Frederick Douglass: Prophet of Freedom” (Simon & Schuster).

The Guy recommends the book itself — 888 pages! — and interviews with author David W. Blight, a Yale University history professor who specializes in slavery, abolitionism and the Reconstruction period (Contacts: david.blight@yale.edu or 203-432-8521 or 203-432-3339). Notably, Blight portrays this heroic American with warts-and-all exposure of problematic aspects in public and private life. One example was Douglass’s typically Protestant assertion that Catholic belief in the papacy was a “stupendous and most arrogant lie.”

The touring Douglass moved audiences with addresses, often in churches, that were de facto sermons and made continual use of the Bible. Favorite themes were the Exodus of God’s children from Egypt and the moral denunciations from the Hebrew prophets. This was not a matter of tactical artifice, Blight observes, but an authentic expression of profound spiritual devotion.

In 1831, as a 13-year-old household slave in Baltimore, Douglass experienced a thoroughgoing conversion to — in his own words — “faith in Jesus Christ as the Redeemer, Friend, and Savior of those who diligently seek him.” He was chiefly influenced by sermons of two white Methodists and especially black lay preacher Charles Johnson. Blight says Douglass quickly developed a hunger for Bible reading, saw the world around him “in a new light,” and gained “new hopes and desire” that laid the foundation of his career.

As is frequently the case for Protestants, his faith was further deepened by a fellow layman, Charles Lawson, a semi-literate black laborer. The two would spend endless hours “singing, praying, and glorifying God,” Blight says.
