Before we understood what caused thunder, and earthquakes we were inclined to see God’s presence – as if God in anger sent thunderbolts; and could switch-on rain or sunshine. To understand the laws governing atmospheric conditions does not mean losing faith in God’s providence, but needs to express it differently. Just so, a more traditional believer might think we are becoming godless because we no longer make the sign of the cross when there is lightning, or say god-willing when speaking of future plans. In fact there might well be truer understanding and greater faith than before.
Newman’s criteria, discussed yesterday, are difficult to apply, but others have worked on them since he wrote. He, himself, showed insight gleaned from his own knowledge of the history of ideas within Christianity – pointing out that in the past, at the time of the great heresies, faith always emerged again from deep within the heart of the Christian community, who were not acquainted with theological subtleties.
Karl Rahner, an Austrian Jesuit, began with the fact that we know now what it was in the past that led to present orthodox teaching of the Church. Whatever development was needed to bring us to where we are now, is a lawful development and very likely to be necessary again. He takes the development of doctrine we can see within the New Testament as the model of what development of doctrine should be; because the New Testament is given to us to show what Christian life is and should be. The development is more than a question of logic; the Church teaches the same doctrine, but continues to make explicit what is implicit.
