Please remember that when you quote from the online Catholic Encyclopedia, you are quoting from the 1917 edition. Laws change. Things change. People change. The stock market fluctuates wildly from day to day…
Where was I? Oh yeah, since Vatican Council II (1962) and the the new Code of Canon Law (1983) we now have today’s official stand:
Definition of Abstinence Not eating the meat (muscle, and organs) of animals (warm-blooded and birds). As mentioned, it has nothing to do with red meat, thus chicken and pork are considered meat as much as beef and lamb. Note, too, since organs are prohibited, no sausage or hot dogs or other encased grindings.
Cold blooded creatures (frogs, alligator, mollusks) and fish are not meat.
Also, diary byproducts are not considered meat. You can drink milk, and eat cheese, ice cream, yogurt, etc… Also, animal fat is not considered meat, so go ahead and use the pasta sauce with meat drippings in it.
Why abstinence from meat? I haven’t a friggin’ clue and I’m waiting for a historian to give me a credible citation for its origin rather than “Isn’t is because…?”
When abstinence?
On the Fridays of Lent. And also Ash Wednesday and Good Friday, which are also Days of Fasting.
It used to be every Friday of the year, which is why Catholics got the rep for eating fish every Friday. However, even though all Fridays are still technically penitential days (because Friday is the day Christ was crucified), only the aforementioned Lenten days have the officially sanctioned discipline of abstinence.
What if you eat meat on an abstinence day? Do you have to go to confession, will you go to hell, can you get dispensation to eat corned beef on a St. Patty’s party that falls on a Friday?
There is no canonical censure applied to breaking this ‘rule.’ This is a church-made and human-made law – not a law of God. Therefore, one does not have to confess it, one will not go to hell, and one can dispense themselves from the rule to eat corned beef on a Friday. The rule of thumb is that if you fail to keep the discipline one day, then try to keep it on another day of your choice.
To reform one’s life, however, is a divine Law. Therefore, it is the complete failure to attempt to grow in holiness through spiritual discipline (abstinence, fast, confession, prayer, charity) that is a true evil, and therefore the subject of sin.
Peace.
