My first child, a daughter, will be born in July. In a few years we will be faced with the inevitable situation that our cat Abigail will die. This may seem like a morbid and depressing thought, but it crosses my mind on occasion. I have buried a few animals in my lifetime and it is never a pleasant situation. We become attached, and it is sad to see them go. No doubt my daughter will become attached to Abby, as Angie and I have, and I will have to answer the question: "Did Abby go to heaven?" My answer to my little girl will be "Yes, of course." When she is older I will explain my thinking to her in more detail in the same way that I will explain it now.
Human beings are the crowning achievement of God's creation. Only after he made man did he see that his creation was "very good" (Gen. 1:31). He placed a unique value on man, making us in his image in order that we could participate in the life of the holy Trinity. Man therefore looks forward to his ultimate salvation—to behold God face to face in all his glory and to be in communion with him for eternity. In other words, man looks forward to heaven.
Animals, on the other hand, were not created in the image and likeness of God and were not endowed with souls and, as such, they will not be able to participate in the "beatific vision" of God that man will receive in heaven. However, God values animals (though he values them less than human life, as we also should) or he would not have created them in the first place. We can also assume that because we possess a care and affection for animals that God also does. Because we are made in the image of God, we would not care for our animal friends if God does not. God also takes great pride in the animals in his creation, as he explained to Job and his companions (Job 41). So, even though animals will never see God in the fullness of his glory, I see no reason why they must be excluded from the new heaven and new earth.
The scriptures do not specifically address the place of animals in heaven, nor has the Church ever made an official dogmatic pronouncement on the matter, so Christians are free to believe what they want about the subject (so long as it does not violate things the scriptures do address and/or other dogmas). The scriptures do hint at the subject, though. Isaiah writes that "The wolf will live with the lamb, the leopard will lie down with the goat, the calf and the lion and the yearling together; and a little child will lead them" (Is. 11:6, New International Version). I suppose that he means that creation will ultimately be restored and given balance, an opinion which is supported by St. Paul who had this to say:
The creation waits in eager expectation for the sons of God to be revealed. For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope that the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God [Rom. 8:19–21, NIV].
So, God's creation waits for its redemption which will coincide with man's ultimate redemption. That there will be animals in the new heaven and earth seems to follow logically. I suppose the controversy is whether we will see our pets who have died. I see no reason why not, even though they will not see God in all his glory and their presence or absence will not affect man's infinite happiness in the presence of God. Ultimately, it is up to God whether we will see our pets in heaven. But a God with infinite power who created all that is, seen and unseen, and values all of his creation, certainly is capable of making room for our animals and pets in the world to come. I am reminded of the words of George Frances Alexander with which I shall now conclude:
All things bright and beautiful,
All creatures great and small,
All things wise and wonderful,
The Lord God made them all.
