In Christian churches there is a 40 day period beginning Ash Wednesday and leading to Easter, that is full of meditation, prayer, and sacrifice. This is act of devotion and a spiritual practice.
While this is not a practice that all UUs participate in, it is something from our history and something that we may wish to participate in. The question might come up, “is there a Unitarian Universalist way to practice Lent?” The answer is yes. A calendar has been created by Mr. Barb Greve and Alex Kapitan. The idea is to focus on a particular word each day during lent and on the Sundays we are to reflect on the word and encourage each other to enact it in our lives. Should you choose to participate you can share your reflections with the hashtag #UULent
Here is the calendar for reference.
