The teachings of the church evolved.  They did not spill out suddenly.  The questions that the Church has discussed for centuries, the divinity and humanity of Christ, as well as questions that emerged a few yeas ago.  There were two hundred years between the councils of Nicea and Chalcedon in which to discuss the theology of Christ.  If you have the idea that every question was solved immediately by some foreign person, and that any kind of discussion of our faith is a sign of 
unfaithfulness, weakness, or relativism----there is a real difficulty to that kind of understanding.  


A different atmosphere has to be created in which people can understand what's REALLY central, and what is new.  And lets not have the same criteria imposed for the new issues as they have for the issues that have been discussed for centuries or millennia.
