I too have witnessed several sacraments reduced from communal to private character, to include marriage, baptism/Chrismation, and now we see communion (even when the person is not sick and at home). That does not make these practices laudable or normative. I can see how sacraments could be private to protect the parties from hostile authorities or when it is nearly impossible to conduct them in public. In this day and age, I don't think we need to continue to continue that sort of practice or to emulate the heterodox who consider baptisms and marriages to be for family and invited guests only. I also have a problem with several deviances from the ideal regarding Holy Communion--even though they have a pedigree of sorts: infrequent communion (once of four times a year); imposition of draconian preparation requirements on lay folks even if they commune regularly; private communion when a person is able to attend the DL; and, at times, some folks treating communion (or any Mystery) as magic. Regarding my very last point, we saw that on Pascha when some folks got in line and had to be turned away. They could not understand why, as baptized Orthodox, they could not be given communion without preparation, recent confession or fasting.
