What are the current rules for fasting and abstinence? How do I observe the traditional rules? Both the current legislation and the traditional practices are given below:
Why do we make Penance?
“Unless you do penance, you shall likewise perish.” (Lk. 13:5)
Because we are sinners, justice requires each of us to make recompense to God for the honor we have denied Him by our sins. Because we have misused our goods, our souls and bodies—as well as those of others—the natural law requires us to strive to restore the order we have disturbed by our sins. Thus, the natural law and the Divine Law bind us in a general way to perform acts of penance. In order to help us fulfill this requirement, Holy Mother Church, knowing our weakness and laziness, binds us under ecclesiastical laws to perform works of penance at certain times.
Penance is also useful to obtain better control over our wounded nature. One may refrain himself from a legitimate satisfaction (food, sleep, entertainment, etc.) in order to oblige the body and the passions to obey the direction of the soul. Doing penance, making sacrifices are part of a needed ascetical practice to reform of our inner disorder, the heritage of the original sin. Practiced with the grace of God and prudence (conferring with one’s confessor), it becomes a great means of salvation.
Penance can also be a prayer, a sacrifice of a legitimate good, given to God as a way to recognize His power, to beg for a grace or to manifest one’s love by imitating and being united to Our Lord’s Passion.
