Pattern of terrorist bombing dates?

Is there any significance or pattern to the dates of some of the most notorious terrorist bombings over the past four years? Nobody has publicly established one yet. So in the interests of furthering discussion on the issue, let me point out four coincidences on the calendar of the Roman Catholic Church.

Every day of the year, the Church commemorates the life and death of a saint or other holy person, or marks a significant event in the history of Christendom. The Islamists have waged at least three major bombings on Catholic feast days commemorating a conflict with Muslims; in the other instance, a London bombing, the feast day was for Elizabethan-era Catholics executed in England.

September 11, 2001: "9/11." Feast day of Blessed Louis of Thuringia, a 13th century German prince who died on the Sixth Crusade to free the Holy Land from the Muslims in 1227.

March 11, 2004: Madrid subway bombings. Feast day marking the beheading of St. Eulogius at the hands of Muslim invaders. St. Eulogius was bishop of Cordoba, Spain, who under Muslim rule had been encouraging Christians to stay true to their faith, even under torture and death, and for chronicling the martyrdom of those who suffered and died. The Muslims killed him on March 11, 859 AD for his having aided the escape of a former Muslim woman who had converted to Christianity.

July 7, 2005: London transit bombings. July 7 commemorates three English martyrs, Blessed Roger Dickenson, Blessed Ralph Milner and Blessed Lawrence Humphrey, executed under Queen Elizabeth I for illegal Catholic activity and for refusing to renounce their faith. They were executed on July 7, 1591. This coincidence is noteworthy, because very few Englishmen are commemorated on the Catholic calendar.

July 21, 2005: Second London transit bombings. Feast day of St. Lawrence of Brindisi, who led a German army and defeated Muslim Turkish invaders in Hungary at the Battle of Szekesfehevar in 1601.

This could be a pattern. Or it could be nothing more than a coincidence. Any meaning remains to be seen.

The next Muslim-related feast day on the Catholic Church calendar is September 24, honoring St. Pacificus, who prophesied the 1688 victory of Christian armies over the Turks in Belgrade.

Afterthought: Operation Enduring Freedom, the US response to the 9/11 attacks, began on October 7, 2001. That day is the anniversary of the Battle of Lepanto (1571), a huge naval engagement in the Mediterranean between the Christians, led by John of Austria, and the Muslim Ottomans led by Ali Pasha. In their first major defeat of the Ottomans, the Christians destroyed the Muslim fleet and prepared the way for more than a century of military successes in central Europe.
