Thank you to all who posted - here is what this writer left out in his lack of knowledge - he even failed to quote Francis who spoke at this event:

Key points:

One cannot preserve doctrine without cultivating its development. One also cannot tie it to a narrow and immutable interpretation, without constricting the Holy Spirit and its action. 

Tradition is a living reality, and only a limited viewpoint can imagine the “deposit of faith” as something static. One cannot put the Word of God in mothballs, as if it were an old blanket one had to preserve from vermin. No! The Word of God is a dynamic reality, always living, and it develops and grows, for it is ordered toward a fulfillment which humans cannot stop
