Their Jesus is not looking very friendly here, he has such a weird expression on his face... Is he looking at Judas?
But John is certainly looking extra lovey-dovey here. The other disciple is looking at the bread like, "WTF? Bread/body? Wine/blood? What??" lol
The language in the paragraph mentioned sounds really hostile, like, "Those who partake... should *CAREFULLY CONSIDER the *WARNING*!!! found at blah blah blah scripture..." And then they repeat the word "warning" two sentences later. Like they really need to CAUTION people about not partaking. Buncha blowhards. They must not like those numbers going up in the Yearbooks....
