Roberto de Nobili (1577-1656) was a key figure in the history of Christian missions in India. Based in Madurai, capital of a Hindu kingdom, he tried to reach the local Brahmins by accommodating completely to their way of life. He mastered Indian languages and studied the holy scriptures of Hinduism thoroughly. In many writings, he testified to a remarkable acquaintanceship of Hindu thinking and spirituality. His dialogical attitude brought him into conflict with both conservative Hindus and the leaders of his own Jesuit order. Later generations admired 'the Christian sannyāsī' for his phenomenal knowledge of languages and scriptures and his daring attempts to design Indian means of expression for the gospel. However, during the last quarter of a century, De Nobili has been criticized by Dalit theologians because of his complete adjustment to caste relations, including discrimination against low-caste people.
