first explained to the Church by David C. Pack in 2011, in a four-part sermon series titled “Christ’s Sayings—One Great Theme.” It was then revisited in his early 2014 two-part series, “How a Small Church Does Such Big Things.” RCG members are told to "sell all" and give their excess to support the work of RCG. Publications The RCG's flagship magazine is The Real Truth, of which Pack is editor-in-chief. Pack hosts the program The World to Come, and he has also written a two-volume Biography, and a booklet titled Here Is The Restored Church of God, which contains more descriptions of his church's doctrines and practices. The RCG's literature and programs are offered to the public free of charge. The World to Come: weekly video and daily audio programs preach the church's doctrines Hundreds of free books and booklets, articles, lessons, and magazines (also in Spanish, French, German, Dutch, Afrikaans, Italian, Polish, Swahili, and Chinese) The Real Truth: monthly flagship magazine which analyzes world news in the light of Bible prophecy—is styled as a continuation of The Plain Truth magazine, as it was produced from 1934 through the mid-1980s Bible Introduction Course: 30 lessons which introduce the basic RCG doctrines The Splinter Explanation Packet: a series of ten books, as well as sermons, written for former WCG members The Pillar: a bi-monthly magazine which is published for the church's members Ambassador Youth: a bi-monthly magazine which is published for the church's teenage members Schools and camps The RCG runs Ambassador Center, a two-year institution to train RCG's future ministers and leaders, modeled after the WCG's Ambassador College. The church also runs Ambassador Youth Camp, an annual summer camp for its teenage members. The church discourages conventional 2-person romantic dating among teenagers, preferring group-based social activities. It also discourages participation in blogs, especially among youth, citing concerns over victimization. Wadsworth headquarters The RCG started constructing its world headquarters in Wadsworth, Ohio, in 2012, and it was partially modeled after Armstrong's Ambassador College campus in Pasadena, California. The church's plans for the project include a four-story Hall of Administration building, a 450-seat auditorium, an educational training center, a studio, and a mail-processing building. The project broke ground on May 10, 2012, and the administration building officially opened on June 21, 2013.
