The Society for Promoting Christian Knowledge (SPCK) is the oldest Anglican mission agency in the world, founded by Thomas Bray in 1698. Working to fulfill his vision to "promote religion and learning" and to "propagate Christian knowledge," The USA chapter of SPCK, SPCK/USA, has been expanding the mission of SPCK since 1983. Some of the the projects undertaken by SPCK/USA include:
- Translation of the Education for Ministry (EFM) program into Spanish.
- Production of church music recordings reflecting Hispanic spirit and character, called Unidos.
- Assistance in funding the translation of the Book of Common Prayer into the Lakota language of the Sioux people.
- Support of St Tikhon's Theological Institute in Russia to train over 100 seminarians.
- Purchase of a 20 foot container of paper for the Uganda Bookshop.
- Providing free web assistance and hosting to Episcopal organizations through Episcopal Church Web Hosting (ECWH), an all-volunteer mission of SPCK/USA
- Cooperation with other dioceses to raise funds to print the Book of Common Prayer in Wichi for the Mataco Indians of Northern Argentina.
- Shipping hundreds of thousands of dollars worth of theological books, audio visual materials and equipment, and vestments to seminaries, clergy, and Bible colleges around the world.
The revival of religious teaching was the core of Bray's purpose. Today, Thomas Bray's vision of seeing that libraries are available to those around the world continues through SPCK and SPCK/USA.
