I would like to know the following:
Let us suppose that a the priest, when conferring a sacrament, used ONLY MATTER AND FORM (that is to say, without the other ceremonies instituted by the Church). Would the sacrament produce its TOTAL EFFICACY IN ALL ITS ASPECTS in the same way as if the established ceremonies had been used?
For example, a bishop when ordaining a priest anoints the hands of the future priest with sacred oil; he prays upon him and asks the Holy Spirit to dwell in him. Finally, the form is used for the validity of the sacrament of order, so that he becomes a priest; and even after the matter and form being conferred, others prayers are prayed.
Now, do these prayers really make a significant difference in that priest, so that something would be missing if the priest did not receive these prayers and ceremonies? An accessory grace comes from these ceremonies, for example?
Thank you.
