Perhaps there is a misunderstanding. My argument isn’t CITH never occured, it is that it was ruled as an abuse. You said CITH went on for 1,000 to which I responded ‘not according to my research’ The quotes you provided support that. CITH was banned in the 6thCentury, not the tenth. Now it is allowed by an indult, an exception, as the norm is on tongue while kneeling. Why do you put such vigour into an indult? Do you not wish to show our Lord the greatest reverence when receiving Him in the Blessed Sacrament?
MEMORIALE DOMINI
Instruction on the Manner of Distributing Holy Communion
Sacred Congregation for Divine Worship
Issued on May 29, 1969.
When the Church celebrates the memorial of the Lord it affirms by the very rite itself its faith in Christ and its adoration of him, Christ present in the sacrifice and given as food to those who share the eucharistic table.
For this reason it is a matter of great concern to the Church that the Eucharist be celebrated and shared with the greatest dignity and fruitfulness. It preserves intact the already developed tradition which has come down to us, its riches having passed into the usage and the life of the Church The pages of history show that the celebration and the receptions of the Eucharist have taken various forms. In our own day the rites for the celebration of the Eucharist have been changed in many and important ways, bringing them more into line with modern man’s spiritual and psychological needs. Further, a change has taken place in the discipline governing the laity’s participation in the sacrament. Holy communion under two kinds, bread and wine has been reintroduced. It had once been common in the Latin Church too, but had subsequently been progressively abandoned. This state of affairs had become general by the time of the Council of Trent, which sanctioned and defended it by dogmatic teaching as being suited to the conditions of that time.[1]
These changes have made of the eucharistic banquet and the faithful fulfillment of Christ’s command a clearer and more vital symbol. At the same time in recent years a fuller sharing in the eucharistic celebration through sacramental communion has here and there evoked
the desire to return to the ancient usage of depositing the eucharistic bread in the hand of the communicant, he himself then communicating, placing it in his mouth.
Indeed, in certain communities and in certain places this practice has been introduced without prior approval having been requested of the Holy See, and, at times, without any attempt to prepare the faithful adequately.
It is certainly true that ancient usage once allowed the faithful to take this divine food in their hands and to place it in their mouths themselves.
It is also true that in very ancient times they were allowed to take the Blessed Sacrament with them from the place where the holy sacrifice was celebrated. This was principally so as to be able to give themselves Viaticum in case they had to face death for their faith.
However, the Church’s prescriptions and the evidence of the Fathers make it abundantly clear that
the greatest reverence was shown the Blessed Sacrament, and that people acted with the greatest prudence. Thus, “let nobody . . . eat that flesh without first adoring it”[2] As a person takes (the Blessed Sacrament) he is warned: " . . . receive it: be careful lest you lose any of it."[3] “For it is the Body of Christ.”[4]
Further, the care and the ministry of the Body and Blood of Christ was specially committed to sacred ministers or to men specially designated for this purpose: “When the president has recited the prayers and all the people have uttered an acclamation, those whom we call deacons distribute to all those present the bread and wine for which thanks have been given, and they take them to those who are absent.”[5]
Soon the task of taking the Blessed Eucharist to those absent was confided to the sacred ministers alone, so as the better to ensure the respect due to the sacrament and to meet the needs of the faithful.
Later, with a deepening understanding of the truth of the eucharistic mystery, of its power and of the presence of Christ in it, there came a greater feeling of reverence towards this sacrament and a deeper humility was felt to be demanded when receiving it. Thus the custom was established of the minister placing a particle of consecrated bread on the tongue of the communicant.
This method of distributing holy communion must be retained, taking the present situation of the Church in the entire world into account, not merely because it has many centuries of-tradition behind it, but especially because it expresses the faithful’s reverence for the Eucharist. The custom does not detract in any way from the personal dignity of those who approach this great sacrament: it is part of that preparation that is needed for the most fruitful reception of the Body of the Lord.[6]
This reverence shows that it is not a sharing in “ordinary bread and wine”[7] that is involved, but in the Body and Blood of the Lord, through which “The people of God share the benefits of the Paschal Sacrifice, renew the New Covenant which God has made with man once for all through the Blood of Christ, and in faith and hope foreshadow and anticipate the eschatological banquet in the kingdom of the Father.”[8]
Further, the practice which must be considered traditional ensures, more effectively, that holy communion is distributed with the proper respect, decorum and dignity. It removes the danger of profanation of the sacred species, in which “in a unique way, Christ, God and man, is present whole and entire, substantially and continually.”[9] Lastly, it ensures that diligent carefulness about the fragments of consecrated bread which the Church has always recommended: “What you have allowed to drop, think of it as though you had lost one of your own members.”[10]
