266. Next the cross is traced on the firehead of each child [or, at the discretion of the diocesan bishop, in front of the forehead (see RCIA 33.3, 54)]; at the discretion of the celebrant, and especially if the children are somewhat older, the signing of the other senses may follow. The celebrant alone says the formularies accompanying each signing.
267. The celebrant first says the following formulary.
N. and N., Christ has called you to be his friends. Always remember him and be faithful to him.
Therefore I mark your forehead with the sign of the cross. It is the sign of Christians; let it remind you always of Christ and how much he loves you.
The rubrics then direct the presider to sign each child.
Then RCIA gives two options. If there are no signing of other senses, the parents, sponsors, and catechists are invited to sign the children. The assigned acclamation text is:
Glory and praise to you, Lord Jesus Christ.
But “another suitable acclamation” may be sung.
RCIA 268 gives the signing of the senses. As with adults, either the presider (priest or deacon) may sign or this may be done by parents, sponsors, or catechists. That’s the order of preference given in the rubrics here–a slight change from RCIA 56, in which “special circumstances” are cited for the presider and assisting clergy to sign the group.
The text for signing senses is simplified from the adult rite:
I (we) mark your ears with the sign of the cross: hear the words of Christ.
I (we) mark your eyes with the sign of the cross: see the works of Christ.
I (we) mark your lips with the sign of the cross: speak as Christ would speak.
I (we) mark the sign of the cross over your heart: make your heart the home of Christ.
I (we) mark your shoulders with the sign of the cross: be strong with the of Christ.
I (we) mark your hands with the sign of the cross: touch others with the gentleness of Christ.
I (we) mark your feet with the sign of the cross: walk in the way of Christ.
While the sign of the cross is traced over the whole person:
I (we) place you entirely under the sign of Christ’s cross in the name of the Father, and of the Son, and of the Holy Spirit: live with Jesus now and for ever.
As with the adult rite, an acclamation may punctuate each signing. Given the tendency for a child’s faith imagination to be sparked, I cannot see why a parish would choose not to sign the multiple senses. Otherwise, just as the adult rite, only with a slightly leaner text.
