===When there is no Liturgy, or only a [[Vespers|Vesperal]] Liturgy ===
According to the [[Typikon]], the Typika is appointed on those days when either there is no liturgy at all, or there is only a [[Vesperal Liturgy]]. The Typika follows the Ninth Hour and contains the [[Typical Psalms]] ([[Psalter|Psalms]] 102 and 145) and the [[Beatitudes]] that would otherwise have been done as part of the three [[antiphon]]s of the Liturgy of the [[Catechumen]]s. The text for this type of service can usually be found in the various [[Liturgikon|Liturgika]] and [[Horologion|Horologia]].
This Typika service is a form of [[Pre-Sanctified Liturgy]] held by a [[deacon]] and authorized by the local [[bishop]] when a [[priest]] is unavailable. The deacon distributes [[Eucharist|communion]] to the faithful present at the service. It should be noted that while this service is blessed in some jurisdictions, it is not universally accepted, nor is it of ancient origin. However, the idea of deacons bringing communion to those unable to attend the Liturgy ''is'' an ancient custom, and so it can be argued that the ancient custom provides the basis for this more recent practice.
