Dear brothers and sisters in Christ,

Imagine if the priest or bishop came out to celebrate Mass wearing shorts, a tank top, and flip-flops. Most of us would be shocked and would quickly voice our disapproval. So why do we sometimes apply a different standard to the laity who attend Mass?

Yes, the clergy are ordained to the ministerial priesthood, but every baptized person shares in the common priesthood of the faithful. Both priest and people come to offer the Holy Sacrifice and to receive Our Lord in the Eucharist. While the clergy have prescribed vestments, the laity also have a responsibility to show reverence for God in His house by dressing appropriately — not as if we were heading to the beach or a casual picnic.

Most churches today are air-conditioned, so summer heat is rarely a valid excuse. Even in warmer conditions, it is possible to dress modestly and comfortably at the same time.

The Catechism of the Catholic Church reminds us of the importance of proper bodily demeanor at Mass:“To prepare for worthy reception of this sacrament, the faithful should observe the fast required in their Church. Bodily demeanor (gestures, clothing) ought to convey the respect, solemnity, and joy of this moment when Christ becomes our guest” (CCC 1387).

What does dressing “modestly,” “properly,” or “appropriately” actually look like in practice? A helpful guide comes from the official dress code at St. Peter’s Basilica in Rome, which applies to all visitors regardless of age or gender.

According to the St. Peter’s Basilica dress code:

What to wear:

• Shirts or blouses that cover the shoulders (plain T-shirts, collared shirts, or full-sleeved tops are acceptable).
• Trousers, skirts, or dresses that cover the knees.

What not to wear:

• Sleeveless tops, tank tops, or spaghetti straps.
• Low-cut or crop tops that expose the chest or midriff.
• Shorts, mini-skirts, or anything that does not cover the knees.
• Obscene or offensive clothing or visible tattoos that should be covered.

These guidelines represent a reasonable minimum standard for showing reverence in the presence of the Blessed Sacrament. Many people choose to go further as a sign of love and respect — for example, men wearing a suit and tie, or women wearing a mantilla or chapel veil, in keeping with beautiful Catholic tradition.

As we continue to live out the fruits of the National Eucharistic Revival, let us remember that dressing properly for Mass is a simple yet powerful way to express our belief in the Real Presence of Jesus Christ in the Eucharist. It is a concrete act of love and adoration for Our Lord, who comes to us so humbly in Holy Communion.

May God grant us the grace to honor Him with our whole selves — body and soul — whenever we enter His house.
