How could the Church possibly reject someone trying to live as a faithful Catholic? The Church rejects no one, the Church as tasked by Our Lord tells us what is right and what is wrong, it is we who then accept or reject what the Church teaches.
There are many people who believe that thieving is a legitimate way of making a living. Is not such a mindset intrinsically disordered? Should the Church accommodate them by abolishing the Seventh Commandment?
