Thank you for doing this. I am really annoyed the way some people have seized on the letter and given it an authority it clearly doesn’t merit, and then got angry when I have pointed this out. I even checked the position with the Archbishops Office in England and they confirmed that what you said above AND that Rome is fully aware that this practice continues. Thanks again.
Please read the letter more closely. The letter itself is not binding but it points out that existing Church disciplines prohibit going up for a blessing during Communion. See the part I highlighted.
The letter said that “this matter is presently under the attentive study of the Congregation,” so “for the present, this dicastery wishes to limit itself to the following observations”:
"1. The liturgical blessing of the Holy Mass is properly given to each and to all at the conclusion of the Mass, just a few moments subsequent to the distribution of Holy Communion.
"2. Lay people, within the context of Holy Mass, are unable to confer blessings. These blessings, rather, are the competence of the priest (cf. Ecclesia de Mysterio, Notitiae 34 (15 Aug. 1997), art. 6, § 2; Canon 1169, § 2; and Roman Ritual De Benedictionibus (1985), n. 18).
"3. Furthermore, the laying on of a hand or hands – which has its own sacramental significance, inappropriate here – by those distributing Holy Communion, in substitution for its reception, is to be explicitly discouraged.
"4. The Apostolic Exhortation Familiaris Consortio n. 84, ‘forbids any pastor, for whatever reason or pretext even of a pastoral nature, to perform ceremonies of any kind for divorced people who remarry’. To be feared is that any form of blessing in substitution for communion would give the impression that the divorced and remarried have been returned, in some sense, to the status of Catholics in good standing.
“5. In a similar way, for others who are not to be admitted to Holy Communion in accord with the norm of law,** the Church’s discipline has already made clear that they should not approach Holy Communion nor receive a blessing.** This would include non-Catholics and those envisaged in can. 915 (i.e., those under the penalty of excommunication or interdict, and others who obstinately persist in manifest grave sin).”
