The '''Typika''' (gr. τυπικα ; sl. Обедница or Изобразительны) is a brief service that is appointed by the [[Typikon]] for certain occasions but may also be conducted when a [[priest]] or [[bishop]] is not present. There are various modifications that are made to this service to incorporate elements from the [[Divine Liturgy]], some of which are designed to be led by [[laity|laymen]]; and in some [[jurisdiction]]s, it can also be a service led by a [[deacon]] which includes the distribution of [[Eucharist|Holy Communion]]. When held in a church, the doors of the [[iconostasis]] remain closed and the service is conducted in the [[nave]].
