Inspired by Wisdom from the World’s Religions – Really?

In listing the sources for the living tradition of Unitarian Universalism we claim that “wisdom from the world’s religions… inspires us in our ethical and spiritual life” – with the understanding that “the world’s religions” here means religions in addition to Judaism and Christianity, which are central to our religious heritage. Is that claim of ours a serious one, or do we make it so that we can look good, or feel good?
