It is submitted that in the first place human evolution cannot become the basis of any doctrinal teaching because it is “new doctrine” within the meaning of *Pastor Aeternus*, a document of the first Vatican Council (Vatican l, 1870). This document (*inter alia*) states:
. . . The Roman Pontiffs, moreover, according to the conditions of the time and affairs advised, sometimes by calling ecumenical councils, or by examining the opinion of the Church spread throughout the world, sometimes by particular synods, sometimes employing other helps which divine Providence has supplied, have defined those matters must be held which with God’s help they have recognized as (being) in agreement with Sacred Scripture and apostolic tradition. For the Holy Spirit was not promised to the successors of Peter, that by His revelation they might disclose new doctrine, but that by His help they might guard sacredly the revelation transmitted through the apostles and the deposit of faith, and might faithfully set it forth. . . . (emphasis added)
(The above is taken from the English translation by Roy Deferrari of *Denziger* 30th edition, 1957, B. Herder Book Co. at paragraph 1836, the full text of which explains that the “affairs advised” are matters that have arisen which bishops have referred to Rome for decision.)
The “new doctrine” referred to is obviously doctrine that is completely outside of divine revelation: that is, it cannot be said to have been founded upon the divine revelation contained in Sacred Scripture and/or the ApostolicTradition, or in a logical development of doctrine contained in those sources, which has become part of the Deposit of Faith. Examples of the latter are Our Lady’s perpetual virginity, Her immaculate conception and Her assumption, original sin and purgatory.
*Lumen Gentium*, a document of the Second Vatican Council (Vatican II, 1965), states (with a footnoted reference to *Pastor Aeternus*) that the Roman Pontiff and the bishops “do not admit any new public revelation as pertaining to the divine deposit of faith.”[8](http://www.kolbecenter.org/butel_dof.htm#sdfootnote8sym) What else is human evolution in terms of the Catholic religion but a new public doctrine that can never become part of the deposit of faith
