The Liturgy of the Presanctified Gifts (Greek: λειτουργία τών Προηγιασμένων Δώρων) is a Byzantine Rite liturgical service which is performed on the weekdays of Great Lent wherein communion is received from Gifts (the Body and Blood of Christ) that are sanctified (consecrated) in advance, hence its name; this Divine Liturgy has no anaphora (eucharistic prayer).
The Presanctified is used on the weekdays of Great Lent, a season of repentance, fasting, and intensified prayer when the more frequent reception of communion is desirable; however, the full Divine Liturgy having a joyful character is not in keeping with the somberness of the season of repentance (Eucharist literally means 'thanksgiving') and so the Presanctified is substituted. Although this service may be performed on any weekday (Monday through Friday) of Great Lent, common parish practice is to celebrate it only on Wednesdays, Fridays, and a feast day on which the polyeleos is sung that falls on a weekday. The Typicon also prescribes the Presanctified on the Thursday of the Great Canon (the fifth Thursday of Lent), and on first three days of Holy Week.
