The ledger entry for "Roskus" and "Fibby," written by Ike's father Buck McCaslin, mentions that Roskus was "rased by Granfather in Callina," and that Fibby was "bought by granfather in Callina" (252). This Carolina ancestor, the father of "Old Carothers" McCaslin and so the great-grandfather of Ike, is not mentioned any where else in the novel.
The first time Ike refers to the Bible, he talks about it as the word of God: "He told in the Book," etc. (243). But when Cass challenges him on the subject of race in the Bible, repeating the familiar pro-slavery argument that the enslaved Africans were the accursed "sons of Ham" (246), Ike introduces the idea of "the men who wrote His Book for Him" (246), i.e. the human authors who "transcribed His Words," and often misquoted Him, or misrepresented His will, despite their desire to "write down the heart's truth" (247).
