The mass, every mass, is about Jesus and the Pascal Mystery. There are no masses for children, or teens. There are masses that are directed to those present, and that may be children or teens. But the mass is always about the Pascal Mystery and Jesus.
On the Ascension we are called by the Church to remember Jesus’ promises to the apostles, his ascension, and the angles who called us to remember his return.
The priest may make mention of what is happening in the lives of the children, but if this was a Sunday mass, for the congregation, the message cannot be limited to the children. He could have used the children as a springboard to speak of the actions in Jesus in all of us and that being related to the Ascension, but this mass was the Ascension mass.
Next year, ask to have the mass on a different day like we did in our parish. We had first communions at the usual 6PM Thursday mass so as to not interfere with the proper adoration of God at the Sunday mass.
Even with special written material asking families to refrain from taking videos and still photos, there was still the usual insensitive ones who disregarded the sacrament and needed a photo op. Fr announced the photo op’s after mass, either as a group, as individuals, as families, but he still could not get the people to process prayerfully to communion. A poor example for the children.
Ascension is celebrated once a year, communion everyday. First communion is communion like every other communion. A sacrament of initiation that continues throughout your life. It should be as important for you today as it is for your child on that Feast of the Ascension.
Ask Fr to speak about the meaning of communion on the Feast of Corpus Christi. That is when we remember what communion means. We set a day aside for this. Even this mass should be focused on the Pascal Mystery (of which communion is part).
Last week, on Thursday evening, we had conformation, some weeks we have baptisms and once in a while weddings.
This is probably a little harsh, but I know some priests don’t know how to speak in such a way as to include children in a homily that is addressed to the greater Church.
