RED LETTER BIBLE'S
The inspiration for rubricating the Dominical words comes from Luke, 22:20: "This cup is the new testament in my blood, which I shed for you." On 19 June 1899, Louis Klopsch, then editor of The Christian Herald magazine, conceived the idea while working on an editorial. Klopsch asked his mentor Rev. Thomas De Witt Talmage what he thought of a testament with the Dominical words rubricated and Dr. Talmage replied, "It could do no harm and it most certainly could do much good."
Klopsch published the first modern red letter edition New Testament later in 1899. The first modern, fully rubricated bible was published in 1901. The rubricated bible instantly became popular, and is sometimes favored by Protestant Christians in the United States. Especially in King James Version editions, this format is useful because quotation marks are absent.
