I'm glad you brought this up, because I really believe this is a HUGE misunderstanding of being made in the image of God. Your take on it is very common, but I think it is profoundly wrong. Why? Ok, now you are probably going to be offended by what I'm going to say, but I'm not singling you out. I think MOST Christians have this same mindset about "being made in the image of God." Here's the problem: it's not only an incomplete understanding, imo, but it is rooted in
pride. It's a very anthropocentric and prideful way of thinking about being made in God's image. It pretty much boils down to "Humans are made in Gods' image, animals are not, so because we are so much more advanced and important than them, it's OK to eat or use them as we see fit."
There are so many problems with that I don't even know where to begin.
First of all, there are different ideas on what it means to be made in God's image. Correct me if I'm wrong, but the standard view seems to be that it means we were created with certain (nonphysical) characteristics of God. For example, we are rational, volitional agents, with an understanding of right and wrong. Like God is Spirit, we are spiritual beings. The problem with that view is that we aren't the only ones God created who hold those qualities. Even animals have some reasoning abilities, and they certainly have their own will. And according to the bible, animals have a spirit and soul. Also, angels have those qualities. So that means either angels were also created in the image of God...OR, being made in the image of God means something more than that.
My view is that it means more than just having certain characteristics of God. I believe it also is about our unique role, or "job" we were given. Just as God rules over us and all creation, we were given the job to rule over the animals and to take care of them. In Genesis 1:26, the concept of being made in God's image is in the very same sentence about dominion, so those two concepts are linked. I'll underline the pertinent part:
Genesis 1:26
Then God said, “Let us make man in our image, according to our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth and over every creeping thing that creeps on the earth.”
So we were given dominion AS image-bearers of God, which means we are
not to rule in a selfish, prideful, tyrannical and merciless way... because that is not the way God rules. But dominion in God's image means to rule over the animals reflecting the way God rules, which is with LOVE, MERCY, selflessness, compassion, justice and a genuine caring for their well-being.
Getting back to what you said that caused me to reply....having a prideful, anthropocentric mindset about "being made in God's image" is the exact opposite of what it's about! Was Jesus prideful or humble? Did Jesus come to be served, or to serve? Did Jesus think that because He is so far above us that means He should selfishly use or abuse us because we are not as important as Him? Of course not.
Jesus laid down His life for us, even though obviously God is infinitely more advanced and "above" us in every way. So since were were made in God's image and likeness - should we be humble about being above the animals, or proud of it while we look down our noses at those "unimportant" animals that are "not like us"?
We were given a kingship. But what kind of "kings" do we want to be? Selfish, prideful, self-serving tyrant kings? Or like Jesus, who is the King of kings? Jesus clearly said, "
Be merciful, as your Father is merciful".... He did not say "Because you were made in God's image and the animals weren't, they don't matter, do what you want with them." No. God created the animals, LOVES them, and knows every single one of them. He even made covenants with the animals, and they are included in His promise of the beautiful future world of peace and harmony which will be a restoration of HIS intent from the start. (See Isaiah 11:6-9)
