Because someone has escaped censure temporarily does not mean it will never happen in the future.
Cardinal Ottaviani was head of the dicastery when de Chardin’s books were condemned - but interestingly not put on the List.
Subsequently, Cardinal Ratzinger, Cardinal Avery Dulles and Cardinal Schonborn all have spoken favorably.
So I will see your Dr. Smith and trump you three Cardinals (with no reference implied as to any President).
You may consider smarter than Pope Benedict 16th, But I would suggest the he is widely considered to be the most brilliant theologian alive; and I don’t think there are a large number of people saying the same thing about Dr. Smith.
Understand that I am in no way advocating reading de Chardin and am in agreement that some of his thoughts are less than tightened down’: it is also a fact that he died well before the dicastery cast aspersions on his writings. He never was given the chance to clarify or to rephrase anything, and the presumption that he was heretical flies in the face of holdings by Cardinal theologians as well a one Pope.
What little I have read of de Chardin is far too poetic for my style, and in that alone it does not make for a textbook on a theological subject, but rather a meditation - as exemplified by comments he had made on the Eucharist.
He had a BA in Philosophy and mathematics and taught chemistry and physics in the
College de la Sainte Famille in Cairo (probably as scholastic); his study of theology was prior to ordination. His training was in paleontology and geology and he worked in that area in China.
So his writings were, to put it not entirely politely, a mish-mash of paleontology, evolution and theological reflections on those two studies.
In short, he was not a PhD. in Theology; his degree was in science - geology, botany and zoology. Those who hold him out as a theologian have started off on the wrong foot entirely.
As of 1981, prior to Cardinal Ratzinger becoming head of the dicastery. an affirmation was made continuing the prior letter which warned that his work contained ambiguities and grave theological errors. However, having died in 1955, he never had the opportunity to amend or clarify. He was not censured, but rather his work was; he had the equivalent of a Masters in theology and his main focus was not on theology but rather paleontology, and he was attempting to expand, from a paleontologist point of view, the writings of St Paul, and particularly Col. 1: 15-17.
Was he wroing? Yes. Did that make him an intentional heretic? N., and I submit that when a theologian as bright as (then) Cardinal Ratzinger does not find him so, then your Dr. Smith is wrong in pressing that point.
