Hi Casilda,
If memory serves me correctly, you are Maronite. I am too. You’re right in that Maronites do not have an “official” catechism. The closest we come to a catechism, at least in the U.S., is the book Captivated by Your Teachings, which does make reference to the Catechism of the Catholic Church along with the documents of Vatican II.
The Ukrainian Greek Catholic Church also issued their own catechism, which, from what I’ve heard, also makes reference to the Catechism of the Catholic Church.
Again, the point of the CCC was to serve as a foundation or point-of-reference for the formation of local catechisms. In that sense, the attempt was to be truly universal by incorporating the insights of both the East and the West. The extent of success on that matter is debatable, and I’d argue that it was pretty much a failure when it comes to incorporating the insights of the East, save for a passing reference to the Byzantine tradition here and there. But it is what it is and we Maronites and other Eastern and Oriental Catholics can certainly make use of it according to our needs.
