Church and science can seem like separate worlds, but many scientists appear in pews and pulpits across the UK. ‘Encouraging Christian Leadership in an Age of Science’ (ECLAS) affirms the work of faith-filled scientists who bring their vocation in science to the church, as members and active friends of congregations. ECLAS want to help them create spaces of engagement, build confidence and competence around scientific issues, and foster thoughtful, prayerful communities working in the world. They are funding 22 churches in England and Wales creatively to change the conversation between the church and the scientific world, focussing on topics from climate change to mental health, with the aim of showing how engaging with science can lead to a deeper experience of faith. ECLAS are supported by a grant of £400,000 to enable congregations and organisations to host these projects and shepherd follow-up projects for one or more additional congregations by 2022.
