CCC 375
The Church, interpreting the symbolism of biblical language in an
authentic way, in the light of the New Testament and Tradition, teaches
that our first parents, Adam and Eve, were constituted in an original
"state of holiness and justice."  Council of Trent (1546): DS 1511;
This grace of original holiness was "to share in....divine life."  Vatican II
Lumen Gentium, 2
Pope John Paul II, however, does not hesitate to call the original
grace of Adam by the name of sanctifying grace:
“When the Council of Trent teaches that the first Adam lost the holiness
and righteousness in which he had been established ... this means that
before sin, man possessed sanctifying grace with all the supernatural
gifts that make man "righteous" before God. We may sum all this up by
saying that, at the beginning, man was in friendship with God.” Catechesis,  September 3, 1986
