Because it showed disrespect to the body of Christ to have food in your stomach to mix with Christ. It was also very, very important to catch each and every crumb of the Host . . . that's why a patent (I was an altar boy who held the patent) was placed under the chin of each recipient to catch all particles that dropped from the priest's fingers . . . and ONLY A PRIEST COULD HANDLE THE HOST AND THE PARTICLES . . . NO ONE ELSE . . .
Since Vatican II virtually destroyed all respect for the priest, nuns, and the consecrated host, anyone, including the recipient can handle the host. The host could conceivably be dropped on the floor, picked up, and then eaten. Now, either it was a sin with dire consequences to handle the host or it was not.
In any case, the solemnity and respect for all that was sacred to the church has long since disappeared from most suburban, yuppy, trendy, and non-Bible based Christianity.
Well, first there is no such thing as non-Bible based Christianity.
When Christ had the “first communion”, He and the disciples where eating a meal together, so I guess it wasn’t that big a deal to have food in the stomach.
Vatican II changed none of the things you mention. All of them were changed after Vatican II.
Get your facts right first, then complain.
