From Happy are those who are called to His Supper
Prayerful Recollection - We should prayerfully recollect ourselves prior to coming to Mass. We should strive to arrive on time, allowing ourselves to prepare our minds and hearts for the liturgy. Upon entering the church, we should maintain reverent silence so that we and those around us are able to pray before Mass begins. This will ensure that we are at peace within ourselves and with others. Such recollection helps to eliminate distractions and allows us to focus more easily on the great mystery of the Eucharistic celebration in which we are about to participate. A prayerful and reflective reading of the Scripture selections for the Mass of the day will help make our hearts and minds ready to receive God’s Word more deeply.
The Eucharistic Fast - We are required to keep the Eucharistic fast, that is, refraining from food and drink (except for water and medicines) for at least one hour prior to receiving Holy Communion. This fast demonstrates reverence and respect for the Body and Blood of Christ that we are going to receive. It also teaches us to hunger for Jesus in Holy Communion.
Appropriate Attire - We should also come to the sacred liturgy appropriately dressed. As Christians we should dress in a modest manner, wearing clothes that reflect our reverence for God and that manifest our respect for the dignity of the liturgy and for one another.
