Ichthus Christian Fellowship is a brand founded in 1974 by Roger and Faith Forster. This movement began with a divine mandate to evangelize and bring spiritual life to London. It started with a small group of like-minded individuals who shared the vision of reaching the unchurched.

After facing initial challenges and no support from existing churches, Roger and Faith were commissioned by God to plant a new church with a strong evangelistic heart. Today, Ichthus has grown into a global movement that spreads the love of God not only in London but also in other nations. Ichthus follows a mission-driven approach, focusing on evangelism, serving the poor, establishing praying and worshiping congregations, nurturing believers, and training Spirit-filled leaders.

The brand's strategy includes cell groups, congregations, and celebrations to promote relationships, express pastoral care, and share in the common life together. Ichthus is also involved in various activities like prayer walking, open-air evangelism, community involvement, and Alpha Groups for enquirers. With a legal structure as a Charitable Company Limited by Guarantee, Ichthus is overseen by a board of trustees who are well-qualified and share the brand's vision.

Roger and Faith Forster, the founders, remain actively involved as apostles and trustees, leading the movement. They have extensive experience in Christian ministry and have authored multiple books. With Ichthus, their aim is to bring together believers and new enquirers into loving, relational, Spirit-filled congregations that align with the brand's vision and structures
