Fasting for the Eastern Catholic means there is no consumption of solid food from midnight until noon. Abstinence is refraining from eating meat, dairy products, eggs, alcohol, fish and olive oil. Three approaches to fasting and abstinence have developed. These might be called 1) the Law – that is required of us, 2) the Tradition – that which devout followers adhere to, and 3) the Compromise – that which is most widely accepted. The Holy Synod has permitted each eparch to ease the obligations of fasting while, at the sometime, exhorting all of the faithful to fast according to the ancient tradition. The minimal obligations for the Eparchy of Newton is the approach referred to as the Law.
The Law – that which is required:
The first day of Great Lent and the last three days of Holy Week are days of fasting
All Fridays of Great Lent are days of abstinence from meat
Good Friday is a day of fast and abstinence
The Tradition – that which the devout follow:
Every day of Great Lent is a day of fast and abstinence
On Saturday and Sunday fish, wine and olive oil are permitted.
Saturday and Sunday are not Fast days – food may be taken at any time.
Certain feast days are treated like Saturday and Sunday
Customary Compromises
The First, Middle and Last weeks of Great Lent are kept strictly. The other weeks are relaxed.
Abstinence from meat on all days of Lent.
Abstinence from meat on all Wednesdays and Fridays during Lent.
Also, the minimal fasting requirements for the Byzantine Metropolitan Church sui iuris of Pittsburgh is abstinence from meat, dairy and eggs on the first day of the fast and on Good Friday. Abstinence of meat is on Wednesdays and Fridays.
Good luck with the fast, just make sure you and your spouse are on the same page.
