Romans
Romans has been called "The Constitution of Christianity," "The Christian Manifesto," and "The Cathedral of the Christian Faith." It is known as the most complete compendium of Christian doctrine. The Epistle of Romans was written by Paul during his third missionary journey to Corinth. Paul was intending on making a fourth missionary journey to the western extremity of the Roman Empire. He wanted the Roman church to assist him with making that journey and wrote this epistle to establish contact with the Roman church in preparation for the anticipated visit. The church at Rome was primarily made up of Gentiles and had very little central organization or local church government. Small groups of believers met all over the city, and this is the reason that Paul addressed his epistle to the "saints" rather than to the "church".
