Through the years a close working relationship has obtained between the White Estate trustees and the General Conference. Most of the trustees are members of the General Conference Executive Committee. Various matters, such as promoting the overseas publication of the Ellen G. White material, appropriation of funds to assist in the foreign language publication of Ellen G. White books, and overall planning of Spirit of Prophecy promotion, including preparation of materials for the annual Spirit of Prophecy Sabbath, although intimately related to the work of the White trustees, are beyond the sphere of their direct responsibility. These are handled by the General Conference Committee through a sub-committee known as the Spirit of Prophecy Committee. This committee includes several of the White trustees. The duties of this subcommittee and the working relationship between the General Conference Committee and the White Estate are currently set forth in a joint agreement adopted by the General Conference Committee and the White Estate trustees on Oct. 10, 1957. There is an interlocking and at times overlapping of responsibilities; nevertheless, a smooth and efficient working relationship between the two organizations is maintained.
