The Nativity of the Lord (Christmas)
Our Christmas scripture readings differ depending on what time the Mass is celebrated. There are actually three sets of readings: Vigil Mass (Christmas Eve afternoon 3:00 and 5:00 PM), Christmas at Night (10:00 PM Mass Christmas Eve) and Mass during the Day (9:00 and 10:30 AM Christmas Day).
You are encouraged to review the readings before attending Mass and reflect on their message both for the time and audience for which they were written and also for the specific meaning the Holy Spirit might be speaking to you as you read and pray on them. Then, when you participate in the Mass, you will find a new meaning and a new way of hearing the readings. You will now be participating in the readings and entering into them instead of just listening to them. And while you are at it, here's a fun exercise - try to guess what the homily will be about and see how close you are.
