Lent is the 40 days before Easter in which Catholics pray, fast, contemplate, and engage in acts of spiritual self-discipline. Why do we fast and abstain?
Fasting is a biblical discipline that can be defended from both the Old and the New Testament. Christ expected his disciples to fast (Mt 9:14-15) and issued instructions for how they should do so (Mt 6:16-18). Catholics follow this pattern by holding a partial fast on Ash Wednesday and Good Friday.
Abstinence from certain foods is also a biblical discipline. In Daniel 10:2-3 we read, “In those days I, Daniel, was mourning for three weeks. I ate no delicacies, no meat or wine entered my mouth, nor did I anoint myself at all, for the full three weeks.”
Catholics use a practice similar to Daniel’s when, as a way of commemorating Christ’s Crucifixion on a Friday, they abstain from eating meat on that day of the week during Lent. The only kind of flesh they eat on Friday is fish, which is a symbol of Christ. Information from Catholic.com/Catholic answers
