Rahner the Calvinist? Or Calvin: the good Catholic

'Christ and his salvation are not simply one of two possibilities offering themselves to man's free choice; they are the deed of God which bursts open and redeems the false choice of man by overtaking it. In Christ God not only gives the possibility of salvation, which in that case would still have to be effected by man himself, but the actual salvation itself, however much this includes also the right decision of human freedom which is itself a gift from God. Where sin already existed, grace came in superabundance.'

- Karl Rahner, Theological Investigations V, 124
