Not every Christian denomination recognizes Lent. Some of the denominations that observe the season include:
Lutheran
Methodist
Presbyterian
Anglican
Roman Catholics
Eastern Orthodox
Although Lent isn't mentioned in the Bible, the practice has been observed for centuries. According to Reflections.Cyberpastor.net, the earliest recorded mention is in the writings of church father Irenaus of Lyons (c.130-c.200).
For long term survivors of domestic violence, the season of Lent can be one that helps us focus on our blessings instead of just on our trials. In our day-to-day reorganization after abuse, we sometimes lose sight of the beautiful things that life has to offer. Easter gives us a new beginning and the hope and promise of a better life. Lent can help us prepare for it.
