How is our Christ transfigured through the fasting of the Church?

The purpose of the fasts of the Church is to entreat the Savior to work in all humanity.

First. In weekly fasts (Wednesday and Friday): On Wednesday, the conspiracy to crucify Christ was hatched. Therefore, the believer fasts to thank God who turns the malice of the evil to the service of salvation. On Friday the believer sees, with St. Jacob of Sarug , Mount Golgotha turned into a wedding mount where Christ offers His bride, the Church, her dowry. Thus, the fasts of Wednesdays and Fridays lead us to the day of the Lord who rose from the dead, early on Sunday morning, so that our hearts rejoice and cry out that the Lord may grant us a resurrected life that prepares us for paradise.

Second. The annual fasts :

During the Nativity Fast [Christmas Fast], the believer does not cease praying for all humanity so that the Baby in the manger (Luke 2:7) may dwell in their hearts, minds, and emotions.

During Great Lent the believer rejoices as he shares in Christ’s fast, in order to celebrate the Christian passover. Every day he prays to the Lord to pass his mind, heart, and emotions over to the heavenly life.

During the Apostles’ Fast, the believer’s heart burns with longing to share with the Apostles in preaching of the gospel of Christ.

During Jonah’s Fast , we pray for non-believers that God may work in them as He did with the people of Nineveh.

During St. Mary’s Fast, we pray that Christ may dwell in our hearts just as the Word of God was incarnate in her womb.
