The Church considers Lent of such importance that it has laid for it special rites.
It has its own special tunes, longer period of abstention, special readings and responses, a special rite of burning the morning incense, and special prostration in the Mass before absolving the deacons.
During Lent, a special Katamarus of biblical readings is used and contains readings from the Old Testament to create a special spiritual atmosphere all of its own.
