I know many people who, rather than attending their local parish, will travel great distances to spend every Sunday at a monastery. Pilgrimage to monasteries is of course a wonderful thing and something we should all endeavour to do with some regularity. We're able to be exposed to a form of spirituality that simply cannot exist in a regular parish settings where people have work and family commitments, and are able to bring the benefits of that experience back with us to our local parish communities. The problem arises when we do not have any connection to a local community but treat the monastery as if it was a regular parish. Our parish suffers from our absence while the monastic life suffers from too much outside influence.
While some of the reasons for this phenomenon might be negative - a distorted fetishising of monasticism, or the feeling that people in their local parish just aren't 'holy enough' - I think that for the majority of people it is the simple fact they like the way things are done in a monastery. The services are done reverently, things aren't rushed and corners aren't cut, everything is read and in its proper place; the chanting, even if the voices aren't great, is prayerful; people behave with reverence, they don't talk or move around unnecessarily; generally those who have made the effort to come have come to pray, and if not they at least respect the fact that others have. None of these things are in any way unique features of monasticism. Most people come only for the Sunday Liturgy, the same service celebrated in every other parish in the world. Things like attending Midnight Office at 2am, singing 'Glory to Thee Who hast shown us the light!' at the end of Orthros at dawn, or hearing the prayer 'Christ the true light' of the 1st Hour as the sun finally rises above the horizon, the monks/nuns and small number of pilgrims are left to enjoy in peace. What this shows is that people are not necessarily looking for a monastic experience, nor a monastic form of spirituality, but simply want things to be prayerful and orderly.
Parishes seem terrified at the idea of reading the kathisma or singing the 'Thou Kyrie' at Vespers, of chanting the canon of Matins, or singing the Prokeimenon or Alleluarion in full at the Divine Liturgy, as if adding 10minutes to a service is going to lead to people fleeing. The simple fact is that most people take the end time of the Liturgy and work backwards. The people who only want to be in church for 30minutes will only attend for 30minutes whether it's a 1 hour service or a 2 hour service. In other words, the people who would mind won't notice. Likewise, having some discipline in the churches won't hurt either. Sure, you might upset a couple of people when you tell them that the sanctuary's not a gentleman's club or that the candle desk at the back isn't Speaker's Corner, but not nearly as many as are already upset by the status quo. People always call for reform and modernisation to reinvigorate parishes, but the only thing demonstrably proven to draw people in large numbers, of all ages and backgrounds, is the faithful observance of Orthodox tradition. Greater conservatism, not liberalism, (usually terribly unhelpful terms, I know) is what the Church needs and people actually want.
