Most Catholics can celebrate the feast day of a saint that shares their name. Today is St. Mark's Day.
Before I was born, my parents apparently had the plan that they would name any boys they had after the four Gospel writers. As a result, I ended up being named Mark, which is a pretty common first name for people of my generation -- there were 3 other Marks in my high school class, which out of a class of 150 is rather a lot.
As saints go, Mark is a pretty good patron to have. Mark was not one of the Twelve but came to the faith early and worked with both St. Paul and St. Peter. He also wrote the second Gospel. His works took him to Asia Minor and he was reportedly martyred in Alexandria some time after the year 60 AD. He is also associated with Venice, where St. Mark's Cathedral is located.
Of the four Gospels, Mark's is the shortest and he takes almost a Jack Webb approach to the matter. He lays out the facts of Jesus's life and pays most attention to the miracles, with less attention given to the teachings. Mark worked closely with St. Peter to write his Gospel, which is one reason why the details matter.
My parents couldn't have known that their son would some day wish to write. Although they were both clear communicators, neither were especially writerly in how they lived. Perhaps they knew something, though, when they chose my name. I do know this -- if you are going to have a patron, Mark is a pretty good one to have.
