Q: I just got a question from a youth minister about a Confirmation happening on 6/27/25. That day is the Feast of the Most Sacred Heart of Jesus. The YM was told by the parish Sacristan that no decorations that symbolize the Holy Spirit can be used on that day. First, is that true? Second, where does one find information like this?

A: No, there are no rules forbidding decorations pertaining to the Holy Spirit for a confirmation that takes place during a Mass on the solemnity of the Most Sacred Heart of Jesus.
GIRM 372 says Ritual Masses are prohibited on Solemnities, but not sacraments. So the Confirmation takes place with the presidential prayers and readings of the Sacred Heart. It is silent about decorations.
You may look at the USCCB’s Built of Living Stones starting at §142 for guidelines on religious art.
