Considering the Divine Office of the East is much more complex and lengthy than the western Office, and is not really meant to be prayed alone and is very difficult to adapt to doing so, I was wondering if it would be acceptable to pray a western version of the Divine Office (an Orthodox one such as St Benedict's rule or perhaps a Sarum rule that is authentically pre-schismatic)?
The reason I ask is that even though there are western rite parishes, they are often called into question (justifiably I might add...) as to their Orthodoxy, and their utter lack of success in most cases. So am I better off just avoiding even trully pre-schism Orthodox rules of prayer such as the Blessed St. Benedict of Nursia because of the deadening of such rites through non Orthodox sustainment of said rites? Or could I use it to incorporate a more complete psalter reading through St. Benedict's rule because everything is self contained in a Monastic Diurnal and I can read the entire day office (complete) much much easier than I could even the read a skeletonized version of the office in the Eastern tradition and in about a third of the time...? Or is perhaps the Western Office less conducive to Orthodoxy than the Eastern and should be avoided for this reason?
