It seems pretty obvious to me this artist wasn't paying attention during his catechism class. Perhaps this article speaks to the woeful state of catechesis amongst Catholics. There will, no doubt be much yelling, shouting and righteous indignation but this can also be an occasion for some teaching.
A priest cannot inadvertently consecrate wine; it requires specific intent. Most priests make the intention to consecrate the contents of the chalice resting on the corporal. The notion that such a consecration could somehow affect a nearby vessel betrays an understanding of the sacraments that is magical and repugnant to our understanding as Catholics. Consecrations do not ricochet.
Now lets assume this person had somehow gotten hold of some properly consecrated wine. According to the article he made popsicles out of it. Such a sacrilegious act would no doubt have a serious impact on the soul of the artist but what of the popsicles? Well, our Lord is present in the Eucharist under the appearances of bread and wine. If the appearances of wine are no longer there then neither is Jesus. The popsicles are simply popsicles.
For those of you interested in such things, deconsecrating a host or the precious blood involves dissolving in water until the appearances of bread and wine no longer remain. The water is then disposed of in the earth. Sacristies used to have sinks which drained directly into the earth for just such a reason. Now enough silliness for one morning. My advice is to ignore this pathetic plea for attention on the part of an artist who rejected a faith he did not even properly understand. I need a coffee... bye.
