Selected for publication in this present volume are four of the principal works of Frits Albers wherein the errors of Pierre Teilhard de Chardin, S.J., are exposed and analysed in depth, their impact on critical areas of Catholic life made manifest, and Teilhard's real agenda proved from Teilhard's own words. These are: The author shows that Teilhard's agenda to spread his errors in the Church was continued after his death so that after Vatican II Catholics would be taught these errors were the 'authentic interpretations' of the Council. He further shows that this has had a most disastrous effect on Catholic life on a global scale. The author discusses and analyses in some depth and with much acumen the insidious preparation of this Teilhardian agenda and its widespread post conciliar implementation. He then turns his attention to the documents of Vatican II and shows that they can only be rightly understood (that is to say, in the light of Catholic Faith and right reason) when seen and accepted as a continuation of the uninterrupted Tradition (handing on of Revelation) that has always existed in the Church, and from which evolution has always been absent.
