What are the differences between the Pre-Sanctified Liturgy and the Liturgy of St John?

The Pre-Sanctified Liturgy, traditionally celebrated during Great Lent, is a unique service that involves the distribution of previously consecrated Eucharist, emphasizing repentance and reflection. In contrast, the Liturgy of St. John Chrysostom is a regular Sunday service that includes the full consecration of bread and wine, celebrating the Resurrection and the Eucharist's central role in worship. The Pre-Sanctified Liturgy lacks the full celebratory elements of the Liturgy of St. John, focusing instead on prayer and penance. Additionally, the Pre-Sanctified is typically held in the evening, while the Liturgy of St. John is celebrated in the morning.
