Catherine Mowry LaCugna (August 6, 1952 – May 3, 1997) was a feminist Catholic theologian and author of God For Us.
LaCugna's aim was to make the doctrine of the Trinity relevant to the everyday life of modern Christians.
Building on the work of Karl Rahner,[citation needed] LaCugna argued that the "demise of the doctrine of the Trinity" started when early church theologians had to respond to the teachings of Arius, arch-heretic of the Christian Church.
LaCugna saw Rahner's manners of subsisting and Barth's modes (or ways) of being as too easily adopting the modern notion of individualistic personhood, instead of a relational and interdependent model.
[3] LaCugna's doctrine of the Trinity has been challenged by theologians such as Nicholas Lash and James William McClendon, Jr..[citation needed] Professor LaCugna received two significant teaching awards from Notre Dame University.
