Thomas Aquinas’s theory of habitual grace rests on a generically metaphysical account of the faculties of the soul and of the natural and supernatural habits that perfect them. Bernard Lonergan opened up fruitful avenues for rethinking nature, grace, and virtue in a developmental perspective. His intentionality analysis transposes the conception of human nature; the dynamic state of being in love transposes sanctifying grace; the development of skills provides an analogue for virtue; and the role of love in the development, orientation, and transformation of skills provides an analogy for grace as habitual.
