One of the many things Catholics can learn from secular humanists is how to cope with change and new knowledge.  We're not so good at that.  It took us 400 years to admit Galileo was right.  Now we admit that Darwin was onto something after 125 years.  So I suppose we're getting better.  Catholic doctrine has changed and evolved over the centuries.  I hope it will continue to do so.  Otherwise we may as well join The Flat Earth Society.
