St. Patrick is revered in Ireland. His traditional color is blue, and in fact until recently the flag of Ireland was blue with a gold harp. While everyone loves green, consider having blue as your theme if you are going for a church wedding.

The Irish are a very religious and patient people. Before a wedding could take place, the Banns had to be read at church for three Sundays - to give the couple time to consider their action and to give others the time to object. Even today, people must register to marry at least 3 months beforehand.
