“As often as you do this, do it in remembrance of Me.”
My wife and I take communion at home. It is open to all Christian believers and does not require a priest, pastor, or anybody else some church organization deems a “special” Christian.
However, this woman and her husband profess to be Catholics, and insist that they are Catholic, despite flouting the tenets and doctrines of the Church.
They are the ones demanding to be "special Catholics". You do not have to be Catholic to be a Christian, and if they were simply "Christian believers", there would be no problem with the Pope. If they also just had their "Masses" in private, at home, then odds are the Pope would never find out about it, and problem solved.
There's nothing wrong with "activating" for Church reforms according to your beliefs, but actions have consequences. Why do they want to be Catholic, when they feel the doctrines are wrong? Much easier to join another Church, or be your own Church - both viable options, surely! You just can't be your own Catholic Church...simple!
Wrong. It is a local church ordinance as is clearly demonstrated by passages about it in the new testament.
?? That needs more information. Are you self-communicating with consecrated hosts? Are you home-bound and someone from a Catholic Church brings you Communion?
Otherwise — you are doing YOPIOS — my opinion only.
