Churches in India have been asked to tackle "institutional casteism" at a meeting organised by the World Council of Churches and Indian Christian groups.
Naming caste-based discrimination as "sin, apostasy and rebellion against God", Indian churches have committed to being "zero tolerance zones" for casteism.
As the UN declares caste-based discrimination a human rights violation, Indian Christian leaders have called on the churches to confess that the caste system has not been fully removed from their own communities.
A deep-rooted caste divide among Christians in India's southern Tamil Nadu state has come to the fore after two Catholics were killed at Eraiyur due to police firing during a clash between upper-caste and Dalit church members.
