John Frame has an excellent article on the use of Reformed Confessions.
The quote I enjoy the most is, “I look forward to the time when God will equip his church to write new confessions. The Reformed confessions of the 16th and 17th centuries are wonderful documents that have served the church well. But we need confessions that speak to the issues of our own time: abortion, postmodern ideology, egalitarianism, new spiritualities, ecumenism, the gifts of the Spirit, common grace, the precise role of the Mosaic law the status of non-Christian religions, the obligation of Christians to the poor, the nature of worship, biblical standards for missions and evangelism, and, indeed, the nature of confessional subscription. We need confessions also that can state the old Reformed and biblical doctrines in contemporary language and support those doctrines with the biblical scholarship that has developed over the last 400 years.”
