The Foundation for Sacred Arts
The Holy Father Speaks (quotes on the arts)
John Paul II's Letter to Artists
A call for artists and composers is here. The submission deadline is December, 2009.
Isn't it lovely -- vital, really -- to be reminded that God is the author of beauty? All that is true, all that is good, all that is beautiful originates in and through Him. Artistic expression is not an unecessary "extra" but is an authentic path to God, as all things beautiful point to Him.
