No, you don't have to worry. Most Democrats who call themselves Catholic are apostates. If receiving Communion was that important to John Kerry, he wouldn't have divorced his first wife, married the second without benefit of annulment, then vote down bills outlawing partial birth abortion. His pro choice votes are in direct violation of Church teaching. So he is publicly saying he's Catholic, in fact using it as a political tool, while standing there publicly violating Church teaching. The Church has every right to refuse him Communion, and while they're at it, they need to shovel Teddy out of the family pew permanently.
It comes down to this: do you want to be a politician or a Catholic who follows his/her religion?
"If receiving Communion was that important to John Kerry, he wouldn't have divorced his first wife, married the second without benefit of annulment, "
Wow - good point! How many politicians, (D) or (R), are guilty of this Catholic transgression? Or are only Dems possible of sin in the Catholic Church?
