From a reader…
I attend daily Mass in my local parish and one local priests (who is not newly ordained) always omits commingling a particle of the Host into the precious blood after consecration. He fractures the Host into four pieces for distribution and does so only after he’s begun the Angus Dei… but never drops a particle. Am I being too picky? Am I over participating? If not how to proceed? I am afraid that he won’t take kindly to my questioning his rubric. But if I have firm grounds
If the priest is NOT properly doing the co-mingling, various called the “Immissio” or “Commixtio”, then, no, you are not being overly picky.
That part of the rite is not to be omitted.
It is of monumental symbolic meaning. Among the things that the fraction of the Host represents are the three forms of the Church, Triumphant, Suffering and, for the piece put into the chalice, Militant (us).
If the priest is not the pastor, address yourself to him. If this is the pastor, you might ask him to explain that part of the rite. If that doesn’t produce positive results, try to develop a chain of correspondence and bring it to the bishop.
This is a touchy situation, it seems. However, you have the right to make your concerns known. Redemptionis Sacramentum 183 ff.
