What will it take for Prime Minister Narendra Modi to speak out about the mounting violence against India’s religious minorities? Attacks at Christian places of worship have prompted no response from the man elected to represent and to protect all of India’s citizens. Nor has he addressed the mass conversion to Hinduism of Christians and Muslims who have been coerced or promised money. Mr. Modi’s continued silence before such troubling intolerance increasingly gives the impression that he either cannot or does not wish to control the fringe elements of the Hindu nationalist right.

Recently, a number of Christian churches in India have been burned and ransacked. Last December, St. Sebastian’s Church in East Delhi was engulfed in fire. Its pastor reported a strong smell of kerosene after the blaze was put out. On Monday, St. Alphonsa’s Church in New Delhi was vandalized. Ceremonial vessels were taken, yet collection boxes full of cash were untouched. Alarmed by the attacks, the Catholic Bishops’ Conference of India has urged the government to uphold the secular nature of India and to assure its Christians they are “protected and secure” in their own country.

There is also concern about the mass conversions. Last December, about 200 Muslims were converted to Hinduism in Agra. In January, up to 100 Christians in West Bengal “reconverted” to Hinduism. Hard-line Hindu nationalist groups, like the Vishwa Hindu Parishad (V.H.P.) and the Rashtriya Swayamsevak Sangh (R.S.S.), make no secret of their support for a “homecoming” campaign designed to “return” non-Hindus to the fold. More than 80 percent of Indians are Hindu, but Pravin Togadia of the V.H.P. says his organization’s goal is a country that is 100 percent Hindu. The only way to achieve that is to deny religious minorities their faith.

The V.H.P. is reportedly planning a mass conversion of 3,000 Muslims in Ayodhya this month. The destruction of the Babri Mosque there in 1992 by Hindu militants touched off riots between Hindus and Muslims across India that left more than 2,000 people dead. The V.H.P. knows it is playing with fire.
