From the London Mail [caution tabloid]:
St. Francis de Sales was closed by the Archdiocese of St Louis in June 2005, and the church was forced to merge with another local parish. The cathedral was scheduled to be torn down and sold, but was saved that July when Cardinal Raymond Leo Burke made the church an Oratory where Mass is strictly administered in Latin.
St Francis de Sales is now one of about 450 churches across the country that regularly celebrate the traditional Latin Mass and is seemingly booming. A typical Sunday will see more than 700 people fill the pews of the cathedral to partake in a nearly two-hour long service where almost no English is spoken, according to the St Louis Post-Dispatch.
