So, we can not drink, eat or smoke (and 1ke, I use that example becuse it is my only sin and actually smoking is not a sin.) one hour before Communion.
We are not to eat or drink before receiving the Eucharist. Smoking is neither eating nor drinking, it is not ingested.
The purpose of the Eucharistic fast is to abstain from what the Church terms profane food and drink in preparation for
sacred food and drink.
We are to solemnly prepare spiritually by examination of conscience and prayerful approach to the sacrament. We are equally to prepare our physical bodies by refraining from the profane in preparation for the sacred-- the Eucharistic food should not be commingled with anything as we receive it.
From St. Augustine, Letter 54:
…for from that time [of the earliest Church] it pleased the Holy Spirit to appoint, for the honour of so great a sacrament, that the body of the Lord should take the precedence of all other food entering the mouth of a Christian; and it is for this reason that the custom referred to is universally observed. (Ep. 54.6)
I think this whole thing can be narrowed down to one simple issue. We are not supposed to do anything that gives us “joy” before Communion.
You have some odd ideas. I would suggest turning to what the Church
actually teaches, because that is not it at all. It has to do with properly preparing ourselves to receive the very Body, Blood, Soul, and Divinity of Christ into our bodies and the respect that needs to be shown to Christ in the Real Presence. The Eucharistic fast is NOT a penitential fast. Penitetial fasting is not permitted on Sunday and Feast Days.
1384 The Lord addresses an invitation to us, urging us to receive him in the sacrament of the Eucharist: "Truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you."217
1385
To respond to this invitation we must prepare ourselves for so great and so holy a moment. St. Paul urges us to examine our conscience: "Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord. Let a man examine himself, and so eat of the bread and drink of the cup. For any one who eats and drinks without discerning the body eats and drinks judgment upon himself."218 Anyone conscious of a grave sin must receive the sacrament of Reconciliation before coming to communion.
1386 Before so great a sacrament, the faithful can only echo humbly and with ardent faith the words of the Centurion: “Domine, non sum dignus ut intres sub tectum meum, sed tantum dic verbo, et sanabitur anima mea” (“Lord, I am not worthy that you should enter under my roof, but only say the word and my soul will be healed.”).219 And in the Divine Liturgy of St. John Chrysostom the faithful pray in the same spirit:
O Son of God, bring me into communion today with your mystical supper. I shall not tell your enemies the secret, nor kiss you with Judas’ kiss. But like the good thief I cry, “Jesus, remember me when you come into your kingdom.”
**1387 To prepare for worthy reception of this sacrament, the faithful should observe the fast required in their Church.**220 Bodily demeanor (gestures, clothing) ought to convey the respect, solemnity, and joy of this moment when Christ becomes our guest.
So let us say that someone enjoy drinking water and are doing so just before Communion. Is that person sinful? Guess he/she is. Jesus loves us, and I don’t think He mind if we are doing something that we like to do, but then in the other hand, I am not a CC, I did convert, so I can be wrong. Can we listen to music if that make us feel good? Can we walk our dog before mass and Communion if it bring us joy? Can we kiss our wife/husband? Pamper our child? The list is endless if we think about it.
Please stop making stuff up that is neither what the Church actually teaches NOR the purpose of the Eucharistic fast. These non sequiters are getting old.
The purpose of the fast is to prepare our bodies to receive the Real Presence in a respectful manner.
If you disrespect the Eucharist and purposely disobey the authority of the Church, then yes you commit a sin. None of the things you listed do either of those things.
This whole thing is not about coffee, it is about doing something that make us feel good, and if that is a sin, and what make us feel good is not “normally” wrong, how do it become a sin one hour before Communion? I will follow that rule, what more can I, if it is considered a sin.
No, it is about properly preparing yourself to receive Christ in the Eucharist. It is surprising that no one instructed you on why it is important to prayerfully prepare to receive the Eucharist.
It is not about doing something that “makes you feel good” it is about obeying the law of the Church in order to not profane the Eucharist.
