Religion

Eagleton is a Christian and Marxist. Does his argument (as summarized by Stanley Fish) do justice to the claims of secularists? Does it do justice to the claim of secular skeptics such as Freud(I know some people call psychoanalysis a religion) who don't profess the militant secularism described by Fish/Eagleton, but the more modest secularism which says simply that reason can't provide answers for everything but what reason cannot answer can't be answered elsewhere ?
