Religious concepts and vocabulary are certainly censored in these textbooks.

There is not one text reference to characteristic Protestant religious life in these books... The dominant theme is the denial of religion as an actual part of American life.

School textbooks have almost completely excised any reference to America's true religious heritage.

In grades 1 through 4 these books introduce the child to U.S. society - to family life, community activities, ordinary economic transactions, and some history. None of the books covering grades 1 through 4 contain one word referring to any religious activity in contemporary American life.
