By Scott Smith - Thinking about what to give up for Lent? Wondering why we fast during the season of Lent? Why do Catholics (1) pray, (2) fast, and (3) give alms during Lent? What is traditional Catholic fasting and where does this tradition come from? Also, how does this connect to Jesus' Temptation in the Desert?.. So why do Catholics (1) pray, (2) fast, and (3) give alms during Lent?
