The Mission Statement of the National Capital Presbytery states that we will "bear public witness to the love, truth and justice of God in Jesus Christ specifically in the areas of racism and reconciliation." NCP has a talented Dismantling Racism team that has put together a comprehensive list of non-fiction books, children's books, and a host of other resources that can be used for self-education or for local church committees who are organizing study/dialogue and action groups. NCP's website is noted below. The other gateway websites listed are also immensely helpful for the same purposes, especially for individual study and reflection. Each website provides a variety of articles, books, podcasts, interviews, videos, films, and documentaries.
