That would mean that the cartoonist is trying to persuade the church to get back to its calling, and only a catholic would express that concern, however mis-guided by using a method such as this. But a catholic would not have brought Christ into the picture, or the 'Host,' and that would eliminate that possibility. Nor would any other religion of Christ scorn Christ. The jews are not a proselyting religion and would have nothing to gain by profaning Christianity. Atheists live and let live and use the courts to prevent what they perceive to be threats against their right to be 'non-believing.'
Who stands to gain by publishing crap like this? My guess? A proselyting religion or sect which dis-believes that Jesus Christ is the manifestation of the Father and is come in the flesh.
