CCC 302 Creation has its own goodness and proper perfection, but it did not spring forth complete from the hands of the Creator. The universe was created "in a state of journeying" (in statu viae) toward an ultimate perfection yet to be attained, to which God has destined it. We call "divine providence" the dispositions by which God guides his creation toward this perfection:
CCC 337 God himself created the visible world in all its richness, diversity and order. Scripture presents the work of the Creator symbolically as a succession of six days of divine "work", concluded by the "rest" of the seventh day.204 On the subject of creation, the sacred text teaches the truths revealed by God for our salvation,205 permitting us to "recognize the inner nature, the value and the ordering of the whole of creation to the praise of God."206
Then you have the Youcat Catechism, which is claimed to be modeled from the official 1992 Catechism of the Catholic Church, which was released by the Vatican on April 4, 2011 and was translated in more than a dozen languages.
The Bible is not meant to convey precise historical information or scientific findings to us. Moreover the authors were children of their time. They shared the cultural ideas of the world around them and often were also dominated by its errors. Nevertheless, everything that man must know about God and the way of his salvation is found with infallible certainty in Sacred Scripture.
In paragraph 42 YouCat asks: “Can someone accept the theory of evolution and still believe in the Creator?” YouCat answers:
Yes. Although it is a different kind of knowledge, faith is open to the findings and hypotheses of the sciences. A Christian can accept the theory of evolution as a helpful explanatory model, provided he does not fall into the heresy of evolutionism, which views man as the random product of biological processes.
The most egregious parts of YouCat are those which address the issues of sexuality, specifically homosexuality. The bottom line is, YouCat does not treat homosexuality as even a serious condition, much less a sinful state of existence. But YouCat’s teaching is subtle. Note these words in Paragraph 65:
There is no man on earth who is not descended from a union of a mother and father. Therefore it is a painful experience for many homosexually oriented people that they do not feel erotically attracted to the opposite sex and necessarily miss out on the physical fruitfulness of the union between man and woman according to human nature and the divine order of creation. Nevertheless, God often leads souls to himself along unusual paths: A lack, a loss, or a wound—if accepted and affirmed—can become a springboard for throwing oneself into the arms of God. -http://www.faithfulanswers.com/youcat-catechism-weak-on-homosexuality-contraception-euthanasia-evolution-and-scripture/
This is the first time that I have seen a catechism assert this. I have checked the Catechism of Trent, Douay, Baltimore and St Pius X....none mention this "symbolism". Having said that, none of them get into the Creation story in too much detail either.
In a couple of catechisms, however, they clearly state that God rested on the seventh day and, when discussing angels, they state that He created them on the "first day". Nowhere is there any mention or even suggestion that the day really wasn't a literal day.
It appears that the (same) JPII Catechism also discusses the Sabbath and that God rested on the seventh day (re: commandment to keep the Sabbath). So did He really do that on the seventh day or was that just symbolic? It doesn't say.
Bottom line for me: it doesn't surprise me to see what you posted. The JPII catechism is post Vatican II, a time where Modernists have been slowly and subtly changing teachings oftentimes appearing contradictory and causing confusion in the process.
