If audacious journalists or non-Catholics in general deign to approach the altar at mass and receive the Eucharist for the sole purpose of saying "I can do as I please" or to make the statement "Jesus is bigger than your church" then fine, there is no moral police present who are going to screen you or deny you your decision (with rare exception). But that has nothing to do with whatever arguments many want to challenge the magestirium in Rome for passing strict liturgical rules or abiding by Canon law.
You have done nothing to make a case against it being reserved for law abiding and mass attending Catholics only. (and so the author here agrees as well)
People and scholars and leaders of other faiths can attack the Catholic Church all they want because they deem us in error or in bed with the devil or for being bigoted, etc. Fine again. But to be indignant because Rome does not acquiesce and change their ways for your reasons is brazen.
Too lazy to look it up, but St. Paul in one of his epistles makes clear that to receive the body and blood of Christ in a state of serious sin or for whimsical or contemptible reasons is a most egregious act. Not only will the soul receive no divine benefits from consuming the host, it will invariably make them ill, either physically, or more often spiritually.
Protestants are good people --- even JWs, Mormons, and pagans. But as far as I am concerned they still have to go through some real apologetic gymnastics to try to get around the real presence of Christ in the bread and wine once consecrated by a priest at the mass. The real presence was there at the Last Supper, and it was clearly put forth by Jesus in John Chapter 6. Given that premise, treating it lightly (as many, if not most, church going Catholics do) is a sacrilege and very consequential.
And I will not bore the skeptics with numerous Eurcharistic miracles because I am slowly coming to realize that these miracles and manifestations are meant for the faithful, not the unbeliever.
