Chris Hudson from Barnabas in Schools argues that “passionate belief” belongs in the classroom (“We must find a place for religion in education”, Letters, 7 February) and it is certainly becoming increasingly common for religious groups to visit schools as part of their missionary work.

Providing students with a good understanding of religious and secular world views is a valid educational aim, and occasional visits from members of belief communities may enhance learning, but religious literacy can be achieved without allowing evangelistic groups into schools. Education about religion and belief should be objective and balanced, and never biased towards a specific faith.
