The broad principles of healthful living had been set forth in The Ministry of Healing. However, in Mrs. White's articles which had appeared in the journals of the church, in Testimonies for the Church, and in certain out-of-print books, were many additional messages. These contained needed instruction regarding health principles, the conduct of Seventh-day Adventist institutions, and the promulgation of the health message. The materials were assembled by the White Trustees in Counsels on Health, published in 1923. This 634-page volume, confined to matter which had appeared in print in one form or another, provided a volume of great service to the church and especially to medical personnel. MM ix.3
