It is a marvel to me that Lutherans hold on to the name (ASH Wednesday) but that most Lutheran parishes will not speak of, much less offer, ashes to their congregants. It was a major step forward that LSB in the Altar Book actually anticipates ashes and a separate service with only ashes by offering a rite which can be used alone (as we are doing here at 7 am with ashes separately and with the Divine Service at 7 pm).
The prophet Jeremiah, for example, calls for repentance this way: "O daughter of my people, gird on sackcloth, roll in the ashes" (Jer 6:26). The prophet Isaiah, on the other hand, critiques the use of sackcloth and ashes as inadequate to please God, but in the process he indicates that this practice was well-known in Israel: "Is this the manner of fasting I wish, of keeping a day of penance: that a man bow his head like a reed, and lie in sackcloth and ashes? Do you call this a fast, a day acceptable to the Lord?" (Is 58:5).
The prophet Daniel pleaded for God to rescue Israel with sackcloth and ashes as a sign of Israel's repentance: "I turned to the Lord God, pleading in earnest prayer, with fasting, sackcloth and ashes" (Dn 9:3). Perhaps the best known example of repentance in the Old Testament also involves sackcloth and ashes. When the prophet Jonah finally obeyed God's command and preached in the great city of Nineveh, his preaching was amazingly effective. Word of his message was carried to the king of Nineveh. "When the news reached the king of Nineveh, he rose from his throne, laid aside his robe, covered himself with sackcloth, and sat in the ashes" (Jon 3:6).
Prior to the New Testament period, the rebels fighting for Jewish independence, the Maccabees, prepared for battle using ashes: "That day they fasted and wore sackcloth; they sprinkled ashes on their heads and tore their clothes" (1 Mc 3:47; see also 4:39). In the New Testament, Jesus refers to the use of sackcloth and ashes as signs of repentance: "Woe to you, Chorazin! Woe to you, Bethsaida! For if the mighty deeds done in your midst had been done in Tyre and Sidon, they would long ago have repented in sackcloth and ashes" (Mt 11:21, Lk 10:13).
Thomas Talley, an expert on the history of the liturgical year, says that the first clearly datable liturgy for Ash Wednesday that provides for sprinkling ashes is in the Romano-Germanic pontifical of 960. Before that time, ashes had been used as a sign of admission to the Order of Penitents. As early as the sixth century, the Spanish Mozarabic rite calls for signing the forehead with ashes when admitting a gravely ill person to the Order of Penitents. At the beginning of the 11th century, Abbot Aelfric notes that it was customary for all the faithful to take part in a ceremony on the Wednesday before Lent that included the imposition of ashes. Near the end of that century, Pope Urban II called for the general use of ashes on that day. Only later did this day come to be called Ash Wednesday.
In the 12th century the rule developed that the ashes were to be created by burning palm branches from the previous Palm Sunday. Many parishes today invite parishioners to bring such palms to church before Lent begins and have a ritual burning of the palms after Mass. All of this, of course, well before the time of Luther.
Ashes in the Church were never seen beyond the penitential connection and never were accorded even a quasi-sacramental status. You would hardly know it, though, since some of the largest crowds in the year will show up to receive ashes on Ash Wednesday. Though no holy day of obligation (for Roman Catholics), most would not think of letting Ash Wednesday go by without a trip to church to be marked with an ashen cross on their foreheads.
Funny how things like Lent and Mardi Gras become detached from their liturgical tradition to take on a life of their own. In a couple of weeks we will again be marked with the sign of the cross and show forth in this outward way the repentant heart inside -- remembering well that the work of repentance is the very work of the Spirit within us and nothing about which we can boast.
