Psalms now. St. Louis: Concordia Publishing, 1973

“Corita left the Order that year [1968] and moved to Boston to concentrate on her art. Yet deprived of familiar contexts and influences, her work began to lose its critical force. Her art grew more sentimental and increasingly reliant on platitudes and colour splashes. By the mid-1970s, intense colours and dense pictorial space were replaced by pastel tones and watercolour-derived airiness, and multivoiced compositions gave way to solitary aphorisms.”
