From Paul VI, as he canonized St. Elizabeth Ann Seton:
Being a Saint means being perfect, with a perfection that attains the highest level that a human being can reach. A Saint is a human creature fully conformed to the will of God. A Saint is a person in whom all sin-the principle of death-is cancelled out and replaced by the living splendor of divine grace. The analysis of the concept of sanctity brings us to recognize in a soul the mingling of two elements that are entirely different but which come together to produce a single effect: sanctity. One of these elements is the human and moral element, raised to the degree of heroism: heroic virtues are always required by the Church for the recognition of a person’s sanctity. The second element is the mystical element, which express the measure and form of divine action in the person chosen by God to realize in herself-always in an original way-the image of Christ (Cfr. Rom. 8, 29).
Do read his enthusiasm in declaring “She is a saint!” here.
They should be able to say that about us, too.
