The use of the Pre-Sanctified Liturgy during the period of Great Lent stems from the Byzantine era. This liturgy was celebrated daily during the weeks of Great Lent. This provided the faithful with the opportunity to strengthen themselves through the Eucharist as they participated in the spiritual Lenten journey. A tradition developed within the liturgical life that the Church would remain silent; that is, there would be no Consecration of the Holy Gifts. Since Lent developed into a period of repentance the joyous expression of the Consecration of the Holy Gifts found in the Liturgy seemed out of place. The Pre-Sanctified Liturgy, as the name indicates, uses the Eucharist that has already been consecrated. Thus the Pre-Sanctified Liturgy can be seen more as a service of distribution.
The use of the Pre-Sanctified Liturgy today generally falls to Wednesdays and Fridays of Great Lent as well as Monday through Wednesday of Holy Week. The service structurally is a combination of vespers and the distribution portion of the Liturgy. This would indicate that during Lent the service is an evening service, though in some parishes it is celebrated in the morning. During Holy Week because of the anticipatory placement of the services (that is, orthros services the evening before and vespers in the morning) the Pre-Sanctified Liturgy is offered in the mornings.
There exists a particular richness and beauty found in the readings taken from the Psalms and a special calmness and solemnity inherent in the service itself. Thus the service entices our hearts to repentance and strengthens our souls beckoning us to stand firm with our Lord through His Passion, Crucifixion, and Entombment in order that we may give faithful witness to joyful and glorious Resurrection of our Lord.
