Corpus Christi

 He that eateth my flesh and drinketh my blood hath everlasting life: and I will raise him up in the last day.
For my flesh is meat indeed: and my blood is drink indeed.
He that eateth my flesh and drinketh my blood abideth in me: and I in him.
...
whosoever shall eat this bread, or drink the chalice of the Lord unworthily, shall be guilty of the body and of the blood of the Lord.

Isn't this beautiful?
