Ordinary time is the longest season in the church calendar. It's not called 'ordinary' because it's routine or insignificant; the word comes from Latin and means 'ordered,' like in a series of numbers. Ordinary time, which runs from Trinity Sunday until Advent, is a season where we focus on growing in Jesus in everyday life - that's why the color is green. 

Currently, we're in a series on the book of Genesis that will run through most of November.
