Schools are places of learning and opportunity, and school communities are made up of people with a wide variety of beliefs. Every member of the school community brings their own beliefs, values and faith practices into the school with them. These may not be recognised religious beliefs, but even those who are humanists or secularists will bring their own worldview, values and beliefs into the school. What a person believes shapes their identity and makes them who they are. So no one with integrity can leave their beliefs, religious or otherwise, outside the school.
Schools are not places for evangelism or proselytising. However, a good school will encourage respect for each individual, their religious beliefs and faith commitment. Within the taught curriculum, there are plenty of opportunities to consider religious beliefs, whether directly in RE or more indirectly when studying a character in an English novel. A healthy dialogue in a school will encourage people to speak openly and honestly about their faith and why it is important to them.
Christians, whether pupils, staff or church visitors in schools, need to learn to share their faith appropriately within the school context. Sensitivity and respect for the beliefs of others is important as the majority of pupils or staff are unlikely to share the same commitment to Christianity. Phrases such as 'As a Christian, I believe...' or many Christians believe...' are entirely appropriate and acceptable. The phrase 'We know that God loves us' should be re-phrased 'As a Christian, I believe that God loves each person'. That way it doesn't deny the essential truth of the statement but neither does it imply belief on the part of the listening pupils or staff. Phrases used in this way allow the Christian to be true to their beliefs whilst still challenging and stimulating reflection on the basics of the Christian faith.
