And Dr Gregory DiPippo's post at New Litugical Movement is well worth reading. I want to note the conclusion:
... At the very moment when it seemed that heresy had triumphed in one of the most important and influential sees of Christendom, the true faith was reborn from a single place, and largely through the work of single man. Nor was this the first or last time such an event happened in the life of the Church. Let it therefore be an object lesson to us, never to despair over the sorry condition in which the Church finds itself in a particular time and place, including our own.
We are accustomed to thinking of St Athanasius's solitary struggle for the triumph of the orthodox Faith but the dynamic evinced in his life operates also in other lives, in other regions and in other times.
