Consider the question. In Lent, many Christians commit to fasting, as well as giving up certain luxuries in order to replicate the sacrifice of Jesus Christ's journey into the desert for 40 days. Many Christians also add a Lenten spiritual discipline, such as reading a daily devotional or praying through a Lenten calendar, to draw themselves near to God. The Stations of the Cross, a devotional commemoration of Christ's carrying the Cross and of his execution, are often observed. Many Roman Catholic and some Protestant churches remove flowers from their altars, while crucifixes, religious statues, and other elaborate religious symbols are often veiled in violet fabrics in solemn observance of the event. Throughout Christendom, some adherents mark the season with the traditional abstention from the consumption of meat, most notably among Lutherans, Roman Catholics and Anglicans.
