Contemporary Christian culture in India draws greatly from the Anglican culture as a result of the influence of the erstwhile British Raj. The Anglican Book of Common Prayer is a widely used supplement for worship in the two major Protestant denominations: Church of South India and Church of North India. Today Christians are considered to be one of the most progressive communities in India. Urban Christians are to a greater extent influenced by European traditions which is considered an advantage in the business environment of urban India; this is given as an explanation for the large number of Christian professionals in India's corporate sector. The Christian church runs thousands of educational institutions which have contributed to the strengthening of Christian culture in India.
