This is not a mandatory fast. For those inspire to do more, this can be modified. No meat, no dairy, and Mondays, Wednesday, Friday, no fish, no oil, no wine. You do what is comfortable for you and your family. I personally eat fish throughout the fast. Fast between meals. Start slow and build on it for the next fast!! God will be pleased no matter what you do!!
APOSTLES FAST
The Apostles’ Fast was first established at the First Council of Nicea in 325 AD and is observed from the Monday after All Saints Day through until the Feast of Sts. Peter and Paul.
We fast as usual on Mondays, Wednesdays, and Fridays. No meat, no dairy, no fish, no wine , no oil. On Tuesdays, Thursdays, Saturdays, and Sundays, however, we are allowed fish, wine, and oil.
Tradition tells us that after the Apostles were filled with the Holy Spirit at Pentecost, they began to fast in order to prepare themselves to go forth and preach the Gospel to the world. There is a verse in scripture which is said to have foretold of the Apostles’ Fast.
Luke 5:35 “Can you make the guests of the bridegroom fast while He is
with them? But the time will come when the bridegroom will be taken
from them; then they will fast.”
Because of this, it is customary to concentrate on the Holy Trinity and the apostolic mission of spreading the Gospel to others during this fast.
