It has in the Directory of Masses with Children, n. 17: “Sometimes, moreover, if the place itself and the nature of the individuals permit, it possibly will be appropriate to celebrate the liturgy of the word, including a homily, with the children in a separate, not not too distant location. Then, before the eucharistic liturgy begins, the children are led to the place where the adults have meanwhile celebrated their own liturgy of the word.”
Is this homily, at the children’s liturgy of the word, only to be given by a priest or deacon?
The Instruction on Certain Questions (Ecclesiae de mysterio) has “The homily, therefore, during the celebration of the Holy Eucharist, must be reserved to the sacred minister, Priest or Deacon …”.
Is the Children’s Liturgy of the Word part of the “celebration of the Holy Eucharist”?
Arguments that it is not could be:
The Eucharist takes place at the altar, this is clearly in a different place.
The Instruction Redemptionis Sacramentum has:
"[60.] In the celebration of Mass, the Liturgy of the Word and the Liturgy of the Eucharist are intimately connected to one another, and form one single act of worship. For this reason it is not licit to separate one of these parts from the other and celebrate them at different times or places.[footnote 135: Cf. S. Congregation for Divine Worship, Instruction, Liturgicae instaurationes, n. 2b: AAS 62 (1970) p. 696.]
The footnote has “b. The liturgy of the word prepares and leads up to the liturgy of the eucharist, forming with it the one act of worship. [foonote 11: See Sacramentum Concilium, article 56] To separate the two, therefore, or to celebrate them at different times or places is not permitted. As for intergrating some liturgical service or part of the divine office before Mass with the liturgy of the word, the guidelines are the norms laid down in the liturgical books for the case in question.” (Documents on the Liturgy 1963-1979, Liturgical Press, Minnesota, 1982, ISBN 0-8146-1281-4, page 161).
Having said this is 1970, it was decided in 1973 that the children’s liturgy of the word could be in a different place. So perhaps the Children’s liturgy of the Word was not considered part of the Eucharistic Celebration.
The Instruction Redemptionis Sacramentum seems to consider it a separate rite, by including a footnote to the Directory for Masses with Children as part of this passage:
“4. On the Joining of Various Rites with the Celebration of Mass
[75.] On account of the theological significance inherent in a particular rite and the Eucharistic Celebration, the liturgical books sometimes prescribe or permit the celebration of Holy Mass to be joined with another rite, especially one of those pertaining to the Sacraments.[footnote 157: Cf. especially the General Instruction of the Liturgy of the Hours, nn. 93-98; Roman Ritual, revised by decree of the Second Vatican Ecumenical Council and published by authority of Pope John Paul II: Book of Blessings, editio typica, 31 May 1984, General Introduction, n. 28; Order of Crowning an Image of the Blessed Virgin Mary, editio typica, 25 March 1981, nn. 10 and 14; S. Congregation for Divine Worship, Instruction, on Masses with Particular Groups, Actio pastoralis, 15 May 1969: AAS 61 (1969) pp. 806-811; Directory for Masses with Children, Pueros baptizatos, 1 November 1973:AAS 66 (1974) pp. 30-46; Missale Romanum, Institutio Generalis, n. 21.] The Church does not permit such a conjoining in other cases, however, especially when it is a question of trivial matters.”
By including the Directory for Masses with Children in the footnote it seems to be saying that it has a separate ceremony. But there is nothing like a special stand-alone blessing in the Directory for Masses with Children. So perhaps it is the Children’s Liturgy of the Word that is regarded as a separate ceremony, that may or may not, be joined with the Mass.
Alternatively, if the Children’s liturgy of the Word is regarded as part of the Eucharist, then the 2004 Instruction Redemptionis Sacramentum seems to ban it taking place ina separate location as well as banning a homily by a lay person at it. This effectively bans a Children’s Liturgy of the Word. If this is the intention, it has not been spelt out.
