The purpose of this article is to provoke discussion on the worship of images depicting saints. However, it is not about defending this worship, since this issue has already been definitively settled by the Church. Instead, the article concerns a new problem – the controversies that arose in connection with some modern depictions of saints, mainly in painting. The mildest of these controversies involve paintings, often made on the basis of surviving photographs, showing saints during their ordinary everyday activities, e.g. while working or resting. A much sharper polarization of opinions occurs when the painting reveals the ethos of the saint with all realism, that is including also their imperfections, and even sin. Can such a saint be an object of veneration which, after all, inherently entails following them as role models? Is such veneration not an acceptance and promotion of flaws that contradict biblical morality? Can such images serve a didactic function? Instead, wouldn’t a certain idealization be advisable – the portrayal of a saint as someone perfect, excluding their flaws and weaknesses? The author takes a position on these controversies by formulating criteria for “good” images based on the theological and moral principles of their worship and an analysis of their functions.
