Theology is Communal
...theology is not an individualistic enterprise in which each theologian alone decides what the Bible teaches on any matter but is rather a communal exercise in which the opinions of others, past and present, are of huge importance. Theologians thus build on the work of those who have preceded them, and each succeeding generation adds something, as new insights emerge and the question in focus changes because an old error has appeared in a new form.
