sentences:  Because the Rite of Constantinople evolved as a synthesis of two distinct rites — cathedral rite of Constantinople called the "asthmatiki akolouthia" ("sung services") and the monastic typicon of the Holy Lavra of Saint Sabbas the Sanctified near Jerusalem — its offices are highly developed and quite complex.Two main strata exist in the rite, those places that have inherited the traditions of the Russian Church which had been given only the monastic Sabbaite typicon which she uses to this day in parishes and cathedrals as well as in monasteries, and everywhere else where some remnant of the cathedral rite remained in use; therefore, the rite as practiced in monasteries everywhere resembles the Russian recension, while non-Russian non-monastic customs differs significantly.For example, in the Russian tradition, the "all-night vigil" is served in every church on Saturday nights and the eves of feast days (all though it may be abridged to be as short as two hours) while elsewhere, it is usual to have matins on the morning of the feast; however, in the latter instance, vespers and matins are rather less abridged but the Divine Liturgy commences at the end of matins and the hours are not read, as was the case in the extinct cathedral rite of Constantinople.
