This may be a dumb question and I apologize if it bothers anyone.
In the Catholic Church, there is the Universal Catechism, but also regional Catechisms specific to certain countries or cultures. And, in addition, there is a Catechism specifically for the Ukrainian-Greek Catholic Church. The fact that Eastern Catholics have a catechism designed present Catholic teaching in a manner applicable to Eastern Christians caused me to ponder whether or not there is an Orthodox Catechism which has been written to present Orthodoxy in a manner applicable to Western Christians. A quick online search showed me a few different Orthodox Catechisms, none of which I know anything about in terms of their quality, but nothing which suggested a Catechism for the Western Rite. My initial impression is that this is relatively new so that a resource like this might not have come along yet.
