It In Greek, the mystery is called Εὐχέλαιον (''Euchelaion'', from εὐχή, ‘prayer’, and ἔλαιον, ‘oil’) and in Russian соборование (''soborovanie''), because it is traditionally celebrated by a ''sobor'' (assembly) of priests.  In Greek and Antiochian parishes, it is most commonly celebrated during [[Holy Week]] on Holy Wednesday evening. However, but private services are also neither the [[Typikon]] of the Great Church (which Greeks and Antiochians follow) nor the [[Typikon]] of St Savas (which Slavic traditions follow) provides for its celebration during Holy Week. Celebrations on other days is common. Everyone in the [[parish]] in good ecclesiastical standing may be anointed with the holy oil for the healing of spiritual and bodily ills. As this is one of the [[sacraments]] of the [[Orthodox Church]], it may be administered only to Orthodox Christians.
