Jon,
** If a visitor wants to, and out of common etiquette, should learn about the Mass. Every pew has missalettes that state for Holy Communion, that only believers are to receive the Eucharist.**
And yes, to receive the Eucharist without faith, is indeed a sacrilege, and was the issue behind the Spanish Inquisition when Jews and Moslems were going to Mass and receiving without faith.
You hear plenty about Catholics allegedly worshipping Mary which is a falsehood – and for us a blasphemy against the Mother of God.
But you know very little about Catholic worship from those who actively work against the Church among their followers. The Mass brings us Jesus physically present to the world. When Our Lord died on the Cross, immediately the veil was torn in the Temple. There, prior, God Himself was physically present to the Jewish people, remaining with them at the Mercy Seat, the inner sanctuary of God, that was adorned by two statues of angelic cherubs. Jesus said the Temple would be torn down and rebuilt in 3 days.
Jesus Christ is the one now physically present among us in the tabernacle. There the sanctuary light next to the tabernacle informs us He is there in Eucharistic form. In ancient times, only once a year, the High Priest was the only one allowed by God to enter the inner sanctuary.
Jesus Christ Himself IS the Church. Jesus Christ is both High Priest and the Temple, His kingdom within. So just as the Jews hold the ancient Temple with greatest veneration along with the Torah as coming from God Himself, we know the Eucharist us God Himself.
We are not to approach God uncommonly. And, going back to the sense of sin, we are not to touch Him without faith in Him. It is as simple as that…Just as His words were at the Last Supper, and the foundation and form of worship for 2,000 years…‘This is my Body, This is My Blood’…the Mass is the Memorial, the new form of worship.
(BTW, one of my client’s relatives was a Muranno…this is a Jewish person who grew up in Spain, and have a very quirky inclination to hide their Jewishness to this very day in Spain. There are Murannos in the SW USA, who privately gather to meet to celebrate their Jewishness, but go to Mass and pray the rosary. Anyway, this relative was also a writer and has written several books. She wrote one about herself, where growing up and going to a Catholic girls’ school, she would go up to receive Holy Communion.
What she experienced receiving Holy Communion was that without even trying or thinking, she experienced God and all His goodness. Later she lost her faith in Catholicism…yes she had it as she said, and got caught up in the world. Later she wrote a book on ‘forgiveness’, and said she drew on the Catholic understanding of forgiveness that really helped her in the long run in life that she could not find in anything else, and then shortly later died of cancer.)
Pastors pick up on non-Catholics when they come into the church. From time to time, the priest, upon noting this, informs the attendees that they are welcome to come forward for a blessing by crossing their hands over their chest, but that communion is closed and allowed only for the faithful.
If you don’t believe, then why go up to attempt to do so?
What the priest informs is the same as the missalette.
If a priest gives communion to a non-Catholic, it is not allowed, or there is some extraordinary circumstance involved which is nobody else’s business.
Jesus Christ is now present among us. One must receive instruction and have faith to receive Him. A Protestant can convert, and depending on the time spent and Pastor’s discernment…after proper instruction, can receive the sacraments the very next day. Learning the Church laws is very simple.
And if you commit mortal sin, you must receive the sacrament of penance with true contrition before you can be restored to sacramental communion.
Any Catholic knows the depth and sacred presence of God…and as given here earlier, even a Jew practicing Catholicism has admitted experiencing God and all goodness.
