This Typika service is a form of [[Pre-Sanctified Liturgy]] held by a [[deacon]] authorised by the local [[bishop]], when a [[priest]] is unavailable. The deacon distributes 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 this ancient custom provides the basis for this more recent practice.
