Some of our friends in Christ refer to the season after Pentecost (or Trinity, if you prefer), as Ordinary Time. Just what does that mean, specifically? This dates back to the usage of the traditional Roman calendar, when the ordinary form of the Mass was used.
I think some people don’t see the Ordinary Time/Pentecost/Trinity season as necessarily being of major importance. Neither of the two most important feasts on the calendar fall during this date. We also don’t have anything that equates to Holy Week in scope during this time.
Yet, there’s something about this season that helps build up anticipation towards Advent. Most of the Bible readings done in church during this time seem to focus on the deeds done during Jesus’ ministry. I think maybe this period “in between” the major seasons helps give us extra time to reflect on what Jesus’ earthly life and teachings mean to us. After all, there’s nothing “ordinary” about that!
