Today in 1962 the Holy Office issued a monitum on the writings of Theilard de Chardin. The Jesuit scientist and philosopher had died of a sudden heart attack 7 years before. This is what the warning said -
Several works of Fr. Pierre Teilhard de Chardin, some of which were posthumously published, are being edited and are gaining a good deal of success. Prescinding from a judgement about those points that concern the positive sciences, it is sufficiently clear that the above-mentioned works abound in such ambiguities and indeed even serious errors, as to offend Catholic doctrine. For this reason, the most eminent and most revered Fathers of the Holy Office exhort all Ordinaries as well as the superiors of Religious institutes, rectors of seminaries and presidents of universities, effectively to protect the minds, particularly of the youth, against the dangers presented by the works of Fr. Teilhard de Chardin and of his followers.
Given at Rome, from the palace of the Holy Office, on the thirtieth day of June, 1962.

As always it is important to understand the context in which such a warning was published. The encyclical Humani Generis was published in 1958 in order to 'deal with some false doctrines that threaten to undermine the foundation of Catholic Theology'. In the encyclical Pius XII had taken an nuanced stance on evolution, distinguishing between the soul, held as created divinely, and the physical body, whose development may be subject to empirical and prudent study. Prudently it tried to keep a middle line, not endorsing a comprehensive belief in evolution, nor its outright rejection, because it deemed the evidence at the time not convincing. It allows for the possibility in the future.
However Teilhard did not display any such reservations. His creative engagement with the theory of evolution brought him into conflict with the more cautious approach of Rome. For Teilhard evolution was both the natural process described by scientists and the spiritual process towards God known by the church. He had argued that without biological evolution which produced the human brain, there would be no sanctified souls. His major work The Phenomenon of Man had discussed an evolving Christianity, introduced the idea of a Cosmic Christ. He has since been rehabilitated by John Paul II and Benedict XVI (link).
