Please read Muslim Nation Bans Christians from Using 19 Religious Words, by Kate Tracy, at Christianity Today.
"Following a decision to implement Shari'ah law in the country, the Brunei government has banned 19 Islamic words from use by non-Muslims.
"The words, which include Allah--long used by regional Christians to refer to God—and other words with religious associations, can no longer be used in reference to other religions after the new penal code takes effect in April, according to the Brunei Times.
"The government also plans to implement strict punishment for crimes, including death by stoning for adultery and amputation of limbs for theft, Religion News Service reported in October. Those penalties will take effect in phases, beginning in April..."
"...The country rose this year from No. 27 to No. 24 on Open Doors' World Watch List for severe Christian persecution. The country implements full Islamic law, considers pastors "enemies," and monitors Christians through spies and the police."
