It is absurd for a "Catholic" catechism to teach that an unbaptized man has sufficient knowledge to make an Act of Contrition, yet the same man does not have sufficient knowledge to know that he must be baptized. In fact, when we look at Catholic catechisms in general, most of them contain error in one form or the other.
The Catechism of Trent is the only one which comes to mind which has the aura of infallibility, but as Cathinfo amply proves, and as traditional Catholicism proves, a great body of people even misunderstand Trent.
You, as often is the case, are wrong.
Even a pagan is capable of an act of contrition. It does not require knowledge of Revelation to know that murder is wrong or that incest is wrong, since those come from the natural law.
Aristotle , despite living in pagan Ancient Greece, was able to prove God's existence (the concept of a unique God above the fake pagan gods was not obvious) through pure reason. Of course, most people do not have the intellect necessary to do so, but it shows that God's existence itself does not require someone to know about the gospels at all.
Likewise, many sins can be proven to be sins simply through the use of reason itself. Any woman capable of motherly love would feel that abortion is wrong, because this is what normal humans instinctively know. Only someone who has been deeply perverted by a degenerate society could fool themselves to think otherwise. Anyone who commit an unnatural act like killing their own child, it doesn't matter if they know about the gospels or not, they would be guilty in the eyes of God.
However, how would someone know about baptism without Revelation? That is impossible.
You do not even understand the hierarchy between the knowledge a human can access through reason, and the knowledge given to a human by God through the theological virtue of faith.
Honestly, the fact you have the audacity to think you can teach others about anything regarding the Catholic faith is astounding.
I recommend studying the Thomistic distinction between natural law and positive divine law before continuing this discussion.
There is another important factor to take into account.
The gospels truly are excellent, divine news. Why do you think that is the case?
