Understanding the Mass
The Mass is the central act of Catholic worship — the re-presentation of Christ's sacrifice on Calvary. Here's everything you need to know to participate fully.
Before You Arrive
What to Wear
Dress modestly and respectfully. Business casual is always appropriate. Avoid shorts, tank tops, and casual beachwear.
When to Arrive
Arrive 5-10 minutes early. This gives you time to find a seat and prepare your heart through quiet prayer.
Holy Communion
Only Catholics in a state of grace may receive Communion. If you're not Catholic, you can approach with arms crossed for a blessing.
Following Along
Most parishes have missalettes or worship aids in the pews. Don't worry if you get lost — just follow along as best you can.
