Why abstain from meat?
Because of the spiritual discipline it provides. “In the third year of Cyrus king of Persia . . . ‘I, Daniel, mourned for three weeks. I ate no choice food; no meat or wine touched my lips; and I used no lotions at all until the three weeks were over.'” (Dan 10:1-3) We give up meat, which still today is a luxury in some parts of the world, as a good thing that we offer up in order to remember that Christ is better than food.
