In English, 5th of May. Cinco de Mayo is a national, but not federal, holiday in Mexico. It commemorates the victory of Mexican forces led by General Ignacio Zaragoza Seguin over the French occupational forces in the Battle of Puebla on May 5, 1862. Although the Mexican army was eventually defeated, the "Batalla de Puebla" came to represent a symbol of Mexican unity and patriotism. With this victory, Mexico demonstrated to the world that they were willing to defend themselves against any foreign intervention, especially those from imperialist states bent on world conquest.
In these terms, we should join our brothers and sisters in their celebration. Freedom is a precious reality, generally best understood when it doesn't exist. God's plan is for all to be free, no matter what oppression is attempting to control us. Look to Him today for this miracle.
John 8:36 (NIV)
36 So if the Son sets you free, you will be free indeed.
