Christians in Parliament, at their annual national prayer breakfast, gave 470 leaders time to stop and reflect, sing hymns, pray, and hear the American Presbyterian pastor Tim Keller. One of the themes was, ‘What role can Christianity play in contemporary public life?’ Theresa May said that Christianity had transformed the United Kingdom with its values and teachings, helping to shape the laws, customs and society of the country. She added, ‘Whether you are a Parliamentarian or a constituent, I encourage you to continue your engagement as Christians in public life for the common good of all.’  The Christians in Parliament ethos is for more Christians to respond to God's call and engage positively in party politics and government. Their mission is to make the biblical case for participating in party politics at high-quality events, and connect Christians and churches to people or organisations that can help them engage politically.
