The tradition of three-self trinitarian art continues, in the cartoons of “nakedpastor.” The way your portray a self, is generally by portraying the type of self we’re most familiar with – a human self, or something like one.
At least the Holy Ghost isn’t a bird… but here he look like a kid in a bad Halloween costume. π
If you’re going to cartoon about the Father, Son, and Holy Spirit, it’s hard to avoid this sort of three-self representation. After all, no one wants to see this sort of monster, which was actually banned by the Pope at one point.
One imagines this three-faced critter to be a single self, as there is one head and body, which is what one human self has. (Never mind that he’s sporting three goatees – that just makes him triple-hip.)
And the folks who strongly insist that we can neither model nor come up with a really decent analogy for the Trinity… well, it’s mighty hard to draw nothing! I can just see the Christian cartoonists picketing with signs that say: “Negative mysterianism takes food off of Christian cartoonists’ plates!”
For the record, I’m against (literal) idolatry, but I see nothing whatever wrong with representing Jesus in art, and even God (aka the Father), even in human or humanoid form. (e.g. big faceless figure on throne, as in this great Christian artist) There are of course better and worse ways to do this, but to me, it is not images, but their religious misuse that is the problem.
