We still use these colours. They help remind us that when we are in church we deal with a different concept of time and season. For instance, the New Year of the church begins with the First Sunday of Advent ( the blue), which is normally either the last Sunday of November or the first Sunday of December.
And as you can tell, the season following Pentecost is called "Ordinary" time ( or sometimes Proper time). Here in America that Ordinary time occurs in summer. Folks have a tendency to not be around church as much during summer - obviously people go on vacation, or to the lake, or family reunions. But another reason I think people don't show up as much is because there's nothing special going on -- you know,special things like Advent or Christmas programs, Lenten studies, Holy Week services, Easter cantatas. It's just a time to show up for church.
Imagine for a moment what your relationships in life would look like if you only showed up for the special moments: parties, weddings, anniversaries, even seriously big fights. If we think about it, most of the real foundation of any relationship is not built in the special times, but in the day to day world, the every day ebb and flow of life, the ordinary times of life.
During Ordinary time in church, it's true we don't talk about angels serenading shepherds, or betrayals in the firelight, or empty tombs. We talk about Jesus traveling around and telling stories to folks who were apparently slow on the uptake, healing people he doesn't know; we talk about the early church trying to figure out how to function without Jesus on earth and how to get along with the help of the Holy Spirit. You know - the ordinary times of life.
Hope to see you this ordinary Sunday.
