Dominicæ Cenæ:
To touch the sacred species and to distribute them with their own hands is a privilege of the ordained, one which indicates an active participation in the ministry of the Eucharist. It is obvious [It's obvious that the Church can make laymen quasi-priests, "givers of the sacred" (sacerdotes)‽] that the Church can grant this faculty to those who are neither priests nor deacons, as is the case with acolytes in the exercise of their ministry, especially if they are destined for future ordination, or with other lay people who are chosen for this to meet a just need, but always after an adequate preparation. [So, priests just need "adequate preparation", too? What about the Sacrament of Orders‽]
Very good anti-Communion-in-the-hand video. Reminds me of Mother Teresa's: "Wherever I go in the whole world, the thing that makes me the saddest is watching people receive Communion in the hand," quoted and cited in
this 1997 HPR article.
