On Trinity parental Saturday, it is customary in the Orthodox world to commemorate the dead. This tradition dates back to apostolic times. The Apostle Peter on this day, addressing the Jews, speaks of the Risen Savior: God raised Him up, breaking the bonds of death. The apostolic decrees state that the apostles, being filled with the Holy Spirit at Pentecost, preached to the Jews and pagans our Savior Jesus Christ, Judge of the living and the dead.
Following this tradition, the Holy Church has long called for the commemoration of all the departed pious forefathers, fathers, brothers and sisters before the day of the Most Holy Trinity.
Trinity Saturday is universal and represents the last day of the Old Testament Church before the opening in all its fullness of the Church of Christ on the Day of Pentecost.
In all churches on this day, funeral Liturgies and memorial services are performed. In the church, you can order the commemoration of the names of the deceased at the liturgy. The commemoration is performed by the priests in the altar, when particles are removed from the prosphora, which are then immersed in a bowl with the Body and Blood of Christ. At this moment, a prayer is read: "Wash, Lord, the sins of those who are remembered here by Your Honest Blood, by the prayers of Your saints." All believers are advised to go to the cemetery after visiting the temple.
