Lent begins with pancakes and ashes

Why do churches often begin the season of Lent with a pancake dinner?
Shrove Tuesday traditionally marks a time of “shriving” the excess from a person’s life, even the pantry. Rich and fatty foods like eggs, milk, and flour were used up before beginning the Lenten period of fasting.

What is the significance of ashes on Ash Wednesday?
The imposition of ashes serve as a reminder that earthly life is finite. “Remember that you are dust and to dust you shall return.” Ashes have also traditionally been a symbol of contrition and repentance throughout history.
