There is only one condition previously required of those who desire admission into these [Methodist] societies: “a desire to flee from the wrath to come, and to be saved from their sins.” It is therefore expected of all who continue therein that they should continue to evidence their desire of salvation, First: By doing no harm, by avoiding evil of every kind, especially that which is most generally practiced, such as: The taking of the name of God in vain. Drunkenness. Slaveholding. Secondly: By doing good; by being in every kind merciful after their power; as they have opportunity, doing good of every possible sort, and, as far as possible, to all men. Thirdly: By attending upon all the ordinances of God; such are: The public worship of God. The ministry of the Word, either read or expounded. The Supper of the Lord. Family and private prayer. Searching the Scriptures. Fasting or abstinence.
If there be any among us who observe [these rules] not, who habitually break any among them, let it be known unto them who watch over that soul as they who must give an account. We will admonish him of the error of his ways. We will bear with him for a season. But then, if he repents not, he has no more place among us. We have delivered our own souls.
—The Book of Discipline of the UMC 1996, 70-72
