Millicent Fawcett once described Josephine Butler as ''the most distinguished English woman of the nineteenth century''. Among the first feminist activists, Butler raised public awareness of the plight of destitute women, worked to address human trafficking and led a vigorous campaign to secure equal rights for women before the law. In her pursuit of justice, Butler did as much for women as William Wilberforce did for African slaves within the British Empire, and yet, while Wilberforce remains a household name, Butler is forgotten. Underpinning Butler''s public life of political activism lies the full corpus of her writing and the spirituality that grounded her activism. When Courage Calls offers a profound examination of Butler''s inner life of prayer, defined by her radical sense of justice that was able to transform Victorian society. Such conviction offers us a taste of what might be possible for our own time and culture.
