God does not ask for 'religious' art or 'Catholic' art. The art he wants for himself is Art, with all its teeth
Jacques MaritainSince art is a virtue of the intellect, it demands to communicate with the entire universe of the intellect. Hence it is that the normal climate of art is intelligence and knowledge: its normal soil, the civilized heritage of a consistent and integrated system of beliefs and values; its normal horizon , the infinity of human experience enlighted by the passionate insight of anguish or the intellectual virtues of a contemplative mind.
