The painting of the image is part of the natural process of growing devotion that always occurs prior to canonization. This is the process by which we collectively and organically recognize the sanctity of someone. The official canonization comes after this and does not make someone a saint, it merely accepts what is already known.
You can’t be a doctor by studying pre-Med. That’s all most Great Books programs give us - supporting texts. They ignore the story of Christianity that forms us to contibute to and conserve the cultute - salvation history as described in the Bible, and lived out through our participation in the sacraments. The more intimately we know these texts, the easier it is to worship well and to be Christian in everyday life.
So much of today’s gender wars and identity politics, I feel, emanate from a poor grasp of the Christian understanding of both human and divine love. It is more common, through the popularization of the Theology of the Body, to focus on nuptial love as a type for God's love, and rightly so. But we should be careful not to neglect what the types of paternal and maternal love tell us about God's love too.
