I don't have a catechism. You are quoting the Catechism of the Catholic Church.
That aside, you need a dictionary.
What's missing is "only." The exclusivity is not there, if you have eyes to see and a heart to limit yourself only to what Christ (and the Catechism of His Church) says, rather than what you want.
I guarantee, taking you to school on logic is thoroughly enjoyable to me.
