He served as a professor of philosophy at Haverford College from 1928 to 1964 and visiting professor of theology at Union Theological Seminary from 1961 to 1962. Steere organized Quaker post-war relief work in Finland, Norway and Poland, was invited to participate as an ecumenical observer in the Second Vatican Council and co-founded the Ecumenical Institute of Spirituality. He authored, edited, translated and wrote introductions for many books on Quakerism, as well as other religions and philosophy.

In 1987, he was awarded the Decoration of Knight 1st Class of the White Rose of Finland, in recognition of his post-war relief work in that country.
