Confirmation: "empty words and cold language"

Conclusion of the Roman (Tridentine) Catechism's section on the Sacrament of Confirmation:

Admonition: Let this, then, serve as a summary of those things which pastors are to expound touching the Sacrament of chrism. The exposition, however, should not be given so much in empty words and cold language, as in the burning accents of pious and glowing zeal, so as to seem to imprint them on the souls and inmost thoughts of the faithful.

How many pastors these days have gotten this memo?: when you're talking about Confirmation, "empty words and cold language"... to be avoided!
