Molokan
Molokans adhere to Old Testament laws in the spirit of the Christian New Covenant. All sects refrain from eating pork, shellfish, or other "unclean" foods, as defined in the Bible. Molokans refer to the sabbath on Sunday. Some refuse to serve on juries or file lawsuits against fellow church members. Church services, led by a Lector, are conducted predominantly in the Russian language, but also in Old Slavonic, which was common to the Orthodox Church. Men and women sit apart, and services are usually quite active. They do not worship saints, and do not worship symbols or images, such as icons or crosses. as the Molokans traditionally practice endogamy and marry within the faith.
