Before terms such as social justice existed, God laid down the Sabbath texts that include green ecology laws as well as commands to care for the poor, not oppress the sojourner, and treat animals equally on the Sabbath. You don’t have to accept liberal theology to validate these ideas. God wants us to be known for our acts of kindness and healing, not our individual politics.
At a luncheon a number of years ago, I met a college student who was studying theology at a religious institution. Needless to say, my dietary practices became the center of our table discussion when I bypassed the animal flesh offered to guests.
