On the Third Sunday of Great and Holy Lent, the Orthodox Church commemorates the Precious and Life-Giving Cross of our Lord and Savior Jesus Christ. Services include a special veneration of the Cross, which prepares the faithful for the commemoration of the Crucifixion during Holy Week.

The commemoration and ceremonies of the Third Sunday of Lent are closely parallel to the feasts of the Veneration of the Cross (September 14) and the Procession of the Cross (August 1). Not only does the Sunday of the Holy Cross prepare us for commemoration of the Crucifixion, but it also reminds us that the whole of Lent is a period when we are crucified with Christ.
