I guess that answers the question about whether or not he supports them. From the BioLogos newsletter:
On March 20–22, 2012, noted evangelical pastor Dr. Timothy Keller hosted the meetings at the Harvard Club in New York City. That in itself has symbolic significance. Harvard University was founded on principles firmly grounded in the Word of God in its pursuit of truth. But since then, Harvard has lost its way. Some wonder if a segment of the church is now in danger of losing its way too.
A statement emerged from each of the first two “Theology of Celebration” meetings, which were held in November 2009 and November 2010. The third meeting, held in March 2012, showed that the conversation has reached a new level of maturity. Given data that was presented at the meeting—which convincingly showed that almost half of America’s protestant pastors hold or strongly lean toward a belief in a universe less than 10,000 years old—there was a deep concern for the church not only in America, but also worldwide. This time, leading evangelical Christians left with not so much a statement as an urgent desire to bring about change. The church of the coming decades cannot divorce itself from matters about which there is scientific certainty.
