My oldest sister claims to be Catholic. She has had six abortions. She's been a drug addict for well over three decades. She's fleeced nearly every member of our family as well as all of her former friends and even her former employers to support her drug use. She hasn't set foot in a church since my wedding back in 1991. I guarantee she voted for Obama.
Anyone can claim to be a Catholic, my friend.
So, the priest asks questions to find out info like you stated when the sacrament of transubstantiation is over with, and communion is given to all who come forward?
If not, why would he give communion to someone such as her?
Perhaps the RCC needs to do a better job of stating just who is and who isn't Catholic, then.
If there are this many who are pro-Obama, pro-leftists, then I guess the number of Catholics that the Vatican touts is a tad too high... Lol.
