Today is Ash Wednesday, the following reflection is taken from a reflection posted on the EWTN web site:
The liturgical use of ashes originated in the Old Testament times. Ashes symbolized mourning, mortality and penance. In the Book of Esther, Mordecai put on sackcloth and ashes when he heard of the decree of King Ahasuerus to kill all of the Jewish people in the Persian Empire (Esther 4:1). Job repented in sackcloth and ashes (Job 42:6). Prophesying the Babylonian captivity of Jerusalem, Daniel wrote, "I turned to the Lord God, pleading in earnest prayer, with fasting, sackcloth, and ashes" (Daniel 9:3). Jesus made reference to ashes, "If the miracles worked in you had taken place in Tyre and Sidon, they would have reformed in sackcloth and ashes long ago" (Matthew 11:21). In the Middle Ages, the priest would bless the dying person with holy water, saying, "Remember that thou art dust and to dust thou shalt return." The Church adapted the use of ashes to mark the beginning of the penitential season of Lent, when we remember our mortality and mourn for our sins. In our present liturgy for Ash Wednesday, we use ashes made from the burned palm branches distributed on the Palm Sunday of the previous year. The priest blesses the ashes and imposes them on the foreheads of the faithful, making the sign of the cross and saying, "Remember, man you are dust and to dust you shall return," or "Turn away from sin and be faithful to the Gospel." As we begin this holy season of Lent in preparation for Easter, we must remember the significance of the ashes we have received: We mourn and do penance for our sins. We again convert our hearts to the Lord, who suffered, died, and rose for our salvation. We renew the promises made at our baptism, when we died to an old life and rose to a new life with Christ. Finally, mindful that the kingdom of this world passes away, we strive to live the kingdom of God now and look forward to its fulfillment in heaven.
Lenten Question Q: What is Lent? A: Lent is the forty day period before Easter, excluding Sundays, which begins on Ash Wednesday and ends on Holy Saturday (the day before Easter Sunday). [This traditional ennumeration does not precisely coincide with the calendar according to the liturgical reform. In order to give special prominence to the Sacred Triduum (Mass of the Lord's Supper, Good Friday, Easter Vigil) the current calendar counts Lent as only from Ash Wednesday to Holy Thursday, up to the Mass of the Lord's Supper. Even so, Lenten practices are properly maintained up to the Easter Vigil, excluding Sundays, as before.]
The only caveat that I would add which is implicit in the above but not stated clearly is that Lent is a season to recall our utter dependence upon God--without God we are as good as dead. Focusing on our weakness, our inability to save ourselves--while at the same time meditating on the life of the Son of God we should be brought to a fuller appreciation for what God has done for us and Easter should be even more meaningful when we realize that because of Jesus--we too can live!
