The church and the world are viewed as distinctly separate institutions and thus Christians are not to be conformed to the world (Romans 12:1-2). To maintain nonconformity to the world, Christians must not be "compromised by worldly dress, amusements, or other worldly attractions." Worldly entertainment provided by such things as motion pictures, musical instruments, radio, television, and the improper use of the internet are to be avoided. Modesty in apparel is particularly stressed. Jewelry, "costly or fashionable attire", and bodily ornamentation detract from Christian simplicity. Their beliefs also include an unwritten dress code. This dress code is most noticeable with the women, who wear mid-length dresses and head coverings.
