Douglas currently still serves at Columbia Theological Seminary as professor of Christian ethics. Additionally, he has served on the boards of Georgia Interfaith Power and Light, the largest faith-based environmental organization in Georgia, the Institutional Review Board of Northside Hospital, and the Presbyterian Association for Science, Technology, and the Christian Faith. He has also served on the Investigative Panel for the State Bar of Georgia, the City of Decatur's Ethics Commission, and the City of Decatur's Climate Resilience Planning Task Force.

Thought
Douglas' work extends into a wide range of areas within the field of ethics. He has published numerous books and has contributed hundreds of articles and book chapters to a variety of publications. He also is the founding editor of @ This Point: theological investigations in church and culture, the online journal of Columbia Theological Seminary, and serves on a number of other editorial and professional boards.
As a Christian ethicist his main focus is integrating religion and justice both within and outside of the church. In 2015, for instance, he participated in a teach-in at Columbia Theological Seminary where he gave a lecture titled, Reformed Theology and Capital Punishment. He has also served on the Study Team on Prospects for a Just Peace in Israel and Palestine, which reported to the Advisory Committee on Social Witness Policy of the Presbyterian Church (U.S.A.). As part of the Presbyterian Church (U.S.A.) his role on this committee and others is to look "at a range of possibilities consistent with the church’s commitment to justice, peace, self determination and related values." He advocates for the Church to create "a more capacious space for disagreement which can be the starting point for learning how to live with each other."
