There are various acts of penitence and spiritual self-discipline observed during Lent, one of those disciplines is a fast that requires us to abstain from meat on Fridays during Lent.
Abstinence from meat is more than just “going without” during Lent or just a reminder that Christ offered His flesh for us on the cross. Abstinence is a form of prayer, a discipline. When we abstain from meat, we focus on Christ and on our souls, rather than on self and on our bodies. It is faith in action, placing our attention on Jesus and offering Him ‘our flesh’ as a sacrifice (Romans 12:1-2), a vessel through which He can and does work.
