“Remember that you are dust,and to dust you shall return.”

Q. Do I have to leave the ashes on my forehead all day?
A small question I've had as a kid and never really heard a definitive answer to. I searched around and came up with the~~ Catholic view:Go with your family to receive ashes at Mass today. Leave them on your forehead as a witness to your faith. Episcopalian view : No. Some choose to wipe the ashes off immediately after the service remembering that Jesus said to “not make a show of your religion” and to “wash you face” (Matthew 6:1, 17). Others choose to leave it on as a sign of mortality and penitence.
