During communion time in a mass, the priest would always raise the round piece of baked flour and say, “This is the lamb og God that takes away the sins of the world.”
But the priest who refused communion to Joe Biden surely did not want his sins taken away. What kind of priest is he? For sure, this priest does now know the basic teachings of Christ.
The obvious beliefs of Catholics is that they may commit sins after sins Monday through Saturday. Then they hear mass on Sunday. But the only true communion is total obedience to Jesus’s true teachings.
