The answer
The bitter herbs remind the people of the bitterness of slavery to sin. Freedom from this sin is through the Passover lamb. St. Jerome looks at the bitter herbs as a symbol of persecution. He writes, "Moreover it is with bitter herbs that the Passover is eaten and "with the unleavened bread of sincerity and truth." He that receives these shall suffer persecution in the world."Answered by His Eminence Metropolitan Youssef (opens in a new tab)
