So essentially, your answer to my question is "yes". What a high view of man and puny view of the Creator of the universe: that He handed the reigns over to man, powerlessly watching as we botched things up, and then having to come and rescue us.
In truth, giving humanity dominion over the earth is not the same as handing over sovereignty or even autonomy. You seem to have those terribly confused. The reality is that all of creation always has been, is, and ever will be under the total sovereignty of God.
You may not like the label, but in my experience those who say they are on some more enlightened ground than Calvinism and Arminianism, are always Arminian at
very least, and more often semi-Pelagian. (Though I do certainly believe that you are not Arm
enian

). It is also a common error to suggest that Arminian doctrine and Calvinist doctrine are "extremes" They are simply two doctrines of Soteriology that are diametrically opposed to one another.
Even if you agree with some points of each, that doesn't make for some mystical middle ground, it simply caters to confusion caused by the logical errors in such an approach.
I would like to encourage you to study what Calvinism and Arminianism actually teach instead of just placing your own preconceived notions over it. It is a common error of the Arminian and semi-Pelagian to look at hyper-Calvinism (which is not Calvinism at all!) and try to paint it as Calvinism. This is not an honest way to deal with the subject, however. I'm happy to recommend some reading if you are interested. You may in the end, choose (of your own will! lol) to vehemently reject Calvinist doctrine, but at least then you would do so with a proper understanding of the doctrines.
