CONCERNING SOME FALSE OPINIONS THREATENING TO UNDERMINE THE FOUNDATIONS OF CATHOLIC DOCTRINE...
..38. Just as in the biological and anthropological sciences, so also in the historical sciences there are those who boldly transgress the limits and safeguards established by the Church. In a particular way must be deplored a certain too free interpretation of the historical books of the Old Testament. Those who favor this system, in order to defend their cause, wrongly refer to the Letter which was sent not long ago to the Archbishop of Paris by the Pontifical Commission on Biblical Studies.[13] This letter, in fact, clearly points out that the first eleven chapters of Genesis, although properly speaking not conforming to the historical method used by the best Greek and Latin writers or by competent authors of our time, do nevertheless pertain to history in a true sense, which however must be further studied and determined by exegetes; the same chapters, (the Letter points out), in simple and metaphorical language adapted to the mentality of a people but little cultured, both state the principal truths which are fundamental for our salvation, and also give a popular description of the origin of the human race and the chosen people.If, however, the ancient sacred writers have taken anything from popular narrations (and this may be conceded), it must never be forgotten that they did so with the help of divine inspiration, through which they were rendered immune from any error in selecting and evaluating those documents.
39. Therefore, whatever of the popular narrations have been inserted into the Sacred Scriptures must in no way be considered on a par with myths or other such things, which are more the product of an extravagant imagination than of that striving for truth and simplicity which in the Sacred Books, also of the Old Testament, is so apparent that our ancient sacred writers must be admitted to be clearly superior to the ancient profane writers.
*Brother, you spotted that heresy with alacrity. Kudos.
And, you are spot on with your analysis.
So, when ya swimming the Tiber?
Catholic Catechism
289Among all the Scriptural texts about creation, the first three chapters of Genesis occupy a unique place. From a literary standpoint these texts may have had diverse sources. The inspired authors have placed them at the beginning of Scripture to express in their solemn language the truths of creation - its origin and its end in God, its order and goodness, the vocation of man, and finally the drama of sin and the hope of salvation. Read in the light of Christ, within the unity of Sacred Scripture and in the living Tradition of the Church, these texts remain the principal source for catechesis on the mysteries of the "beginning": creation, fall, and promise of salvation.
* Well, so much for myths.
BTW, How come YOU don't know the Old Testament is,essentially, useless :)
LOL! I doubt Rome would want me. I don't agree with it on to many things to make the swim.
As to the OT, there is a rather long answer to that question, but the short one is simple. If it is just myth, then the NT makes no sense. If you are talking canon, well that is another thread.
