The Covenant of Christian Conduct
29. We hold specifically that the following practices should be avoided:
29.5. The use of intoxicating liquors as a beverage, or trafficking therein; giving influence to, or voting for, the licensing of places for the sale of the same; using illicit drugs or trafficking therein; using of tobacco in any of its forms, or trafficking therein.
In light of the Holy Scriptures and human experience concerning the ruinous consequences of the use of alcohol as a beverage, and in light of the findings of medical science regarding the detrimental effect of both alcohol and tobacco to the body and mind, as a community of faith committed to the pursuit of a holy life, our position and practice is abstinence rather than moderation. Holy Scripture teaches that our body is the temple of the Holy Spirit. With loving regard for ourselves and others, we call our people to total abstinence from all intoxicants.
Furthermore, our Christian social responsibility calls us to use any legitimate and legal means to minimize the availability of both beverage alcohol and tobacco to others. The widespread incidence of alcohol abuse in our world demands that we embody a position that stands as a witness to others. (903.14-903.16)
(Proverbs 20:1; 23:29-24:2; Hosea 4:10-11; Habakkuk 2:5; Romans 13:8; 14:15-21; 15:1-2; 1 Corinthians 3:16-17; 6:9-12, 19-20; 10:31-33; Galatians 5:13-14, 21; Ephesians 5:18)
(Only unfermented wine should be used in the sacrament of the Lord’s Supper.) (514.9, 530.7, 531.2, 532.1, 802)
34.6. The unprescribed use of hallucinogenics, stimulants, and depressants, and the misuse and abuse of regularly prescribed medicines. Only on competent medical advice and under medical supervision should such drugs be used.
(Matthew 22:37-39; 27:34; Romans 12:1-2; 1 Corinthians 6:19-20; 9:24-27)
903. CURRENT MORAL AND SOCIAL ISSUES
903.14. Substance Abuse
The Church of the Nazarene continues to strongly object to substance abuse as a social malignancy. We encourage church members to take an active and highly visible role and to participate in education and rehabilitation relative to substance abuse and the incompatibility of such use with a Christian experience and a holy life. (2013)
903.15. Alcohol Desocialization
The Church of the Nazarene publicly supports the desocialization of alcohol consumption. We encourage civic, labor, business, professional, social, voluntary, and private agencies and organizations to assist in such desocialization to counteract the advertising and media promotion of the social acceptability of the “alcohol culture.” (2013)
903.16. Tobacco Use and Advertising
The Church of the Nazarene urges its people to continue to speak out against the use of tobacco, both as a health hazard and a social evil. Our historic stand is based on God’s Word, where we are admonished to maintain our bodies as temples of the Holy Spirit (1 Corinthians 3:16-17; 6:19-20).
Our stand opposing the use of tobacco in all its forms is strongly supported by medical evidence, documented by numerous social, governmental, and health agencies around the world. They have demonstrated that it is a major health hazard, and have shown conclusively that its use may produce changes in normal bodily physiology, both serious and permanent.
We recognize that our young people are greatly influenced by the millions of dollars that are spent on tobacco advertising, and its twin evil, beverage alcohol. We endorse a ban on all advertising of tobacco and beverage alcohol in magazines, on billboards, and on radi, television, and other media. (2013)
