The reception of Holy Communion is reserved for practising Catholics in the state of grace. Specifically, to receive Holy Communion: One must be a baptised and practising Catholic, having made a good confession since the last committed mortal sin, if any, in order to be in the state of Grace, and one must not be a public sinner (living in sin with another, married outside the Church, etc.) One must observe at least one hour of Eucharistic fast (water and medicine do not break the fast). The most important requirement is to have a great desire to receive the Body, Blood, Soul, and Divinity of our Lord Jesus Christ.You may humbly approach the Communion rail when the other parishioners do so. To receive Communion, close your eyes, open the mouth wide and extend your tongue smoothly and horizontally. Do not say “Amen.” You might notice some parishioners who refrain from receiving Holy Communion, as there is no obligation to receive it daily, and there are many reasons people would choose to refrain, such as if they have not made a devout preparation. However, “Live in a manner to be able to receive Communion every day!” (St. Augustine). After Mass has concluded, instead of leaving immediately, take some time to make a good prayer of thanksgiving to Our Lord for the gift of Himself in the Most Blessed Sacrament. You will notice other parishioners doing so as well.
