Muscular Christianity, by Cliffort Putney
The goals of the Social Gospel movement, the ideas of men such as G. Stanley Hall and Theodore Roosevelt, Christians' attitudes toward World War I, the development of institutions such as the Federal Council of Churches, the Boy Scouts and the Young Men's Christian Association—these are the sorts of topics Clifford Putney covers. They are, of course, ones that historians of American religion and culture have examined time and again.
