Teaches, supports, approves. Ok, pick your verb. CITH and COTT are both ok by the Church in the U.S.
You are being selective with your posts. You asked what the PREFERENCE is, not the permitted. I never claimed, in fact explicitely said otherwise, CITH was a permitted practice, simply not the preferred.
Regarding St. Basil, he apparently mentions this in his Epistle 93, though elsewhere in the same Epistle he approves of the practice in general as something which can have its good points, but still indicated it was best kept to times of danger or exception:
“It is good and beneficial to communicate every day, and to partake of the holy Body and Blood of Christ. For He distinctly says, “He that eateth my flesh and drinketh my blood hath eternal life.” And who doubts that to share frequently in life, is the same thing as to have manifold life. I, indeed, communicate four times a week, on the Lord’s day, on Wednesday, on Friday, and on the Sabbath, and on the other days if there is a commemoration of any Saint.**** It is needless to point out that for anyone in times of persecution to be compelled to take the communion in his own hand without the presence of a priest or minister is not a serious offence, as long custom sanctions this practice from the facts themselves.**** All the solitaries in the desert, where there is no priest, take the communion themselves, keeping communion at home. And at Alexandria and in Egypt, each one of the laity, for the most part, keeps the communion, at his own house, and participates in it when he likes. For when once the priest has completed the offering, and given it, the recipient, participating in it each time as entire, is bound to believe that he properly takes and receives it from the giver.And even in the church, when the priest gives the portion, the recipient takes it with complete power over it, and so lifts it to his lips with his own hand. It has the same validity whether one portion or several portions are received from the priest at the same time.”
I should point out St. Basil’s reference to the Desert Solitaries leaves out that these monks were often granted a dispensation from the ordinary to do this, were given a special blessing (as EMCs are supposed to be) and were to cleanse their hands, preferrably with water, but with incense if necessary and then receive. A small ceremony (which has fallen into disuse) does still exist to provide for giving Holy Communion outside the context of a Mass. This was very common until the Council of Trent, which made Holy Communion at Mass the highly preferred context for receiving the Eucharist. A study of the Holy Eucharist in the 1950’s Dominican work, Come, Let us Worship, discusses this at length.
I repeat, the manner of receiving CITH in ancient practice is different then now. One did not pick up the host and place it in your mouth, but lifted the whole of both hands to the mouth and place the Sacred Host directly in. Again, in Roman practice a cloth was generally used, and apparently the rubric for this persisted until 1962, long after CITH fell out of practice.
To wit:
“The tradition of the Roman Church points to the use of a linen cloth (not metal of any sort) at Holy Communion. The purpose of this cloth was to receive the Sacred Particles which might fall from the hand of the priest. The present regulations of the Church embody the Roman practice of old. The Missal requires that a linen cloth or white veil be extended before those who are to receive Holy Communion : “Interim minister ante eos extendit linteum, seu velum album.” The Ritual insists on a clean linen cloth for this purpose: “et ante eos linteo mundo extenso.” Neither is the Caeremoniale Episcoporum silent on this point, as it demands a white cloth (“mantile album”) for Communion. Let us add in passing that the Pontificale in the rubrics for the ordination of a priest (singular form) speaks of a mappula to be used at the Communion of the newly ordained. Positive law then, as well as the usage of centuries, requires that the laity in receiving Holy Communion hold a linen cloth between themselves and the ministering priest. Custom tolerates a card or small square of linen, instead of a cloth, at altars where communions are not numerous or frequent.” Fr. A.B. Meehan, 1917.
This was apparently renewed in 1922 and 1929, by the Congregation of Rites.
The idea of placing a paten under the chin was apparently meant to replace the white cloth for COTT, but this was apparently a general practice, and not strictly speaking necessary or even the rubric(!) of the Church. The white cloth, or even card, was still the required practice. This in later usage was simply spread over the altar rail as an addition to the paten, and not as the primary intermediary it once was.
