Reading the readings before Sunday also allows you to think about the readings in the days leading up to Mass and contemplate what God may want to speak to you in this particular passage.
Once you finally arrive at Mass and sit down to listen to the readings, everything will be familiar to you and if by chance your mind wanders for a bit (I know, that never happens) when the priest begins his homily, you will not be confused when he makes references to the readings of the day.
Another benefit of reading the Mass readings before Sunday is the ability to look at the context of the reading. Often when we arrive at Mass on Sunday, the Gospel will seem out of place and you will not know what happened before or after the event recounted. This allows you the ability to understand where Jesus is coming from in the Gospel passage and where he is going. If you happen to have a bible with commentary in the margins, this will further add to your reading and give you historical and theological context to what you read.
In the end, you can only benefit from reading the Mass readings beforehand, especially if you find your mind wandering during Mass or have difficulty wrangling a toddler who doesn’t understand (or care) that she needs to be sitting during Mass.
The beat place to find the current readings is at the USCCB website. Otherwise there are numerous apps (like the myParishApp) that have the Mass readings built-in.
So next time you go to Mass, consider reading the Mass readings for the day.
