From Bishop Kallistos Ware:

Now there is a specific reason for this mysterious and indefinable character of human personhood. And this reason is given to us by St. Gregory of Nyssa, writing in the fourth century. "God," says he, "is a mystery beyond all understanding." We humans are formed in God’s image. The image should reproduce the characteristics of the archetype, of the original. So if God is beyond understanding, then the human person formed in God’s image is likewise beyond understanding. Precisely because God is a mystery, I too am a mystery.
Now in mentioning the image, we’ve come to the most important factor in our humanness. Who am I? As a human person, I am formed in the image of God. That is the most significant and basic fact about my personhood. We are God’s living icons. Each of us is a created expression of God’s infinite and uncreated self-expression. So this means it is impossible to understand the human person apart from God. Humans cut off from God are no longer authentically human. They are subhuman...
...Self-centeredness is in the end coldness, isolation. It is a desert. It’s no coincidence that in the Lord’s Prayer, the model of prayer that God has given us, and which teaches what we are to be, the word "us" comes five times, the word "our" three times, the word "we" once. But nowhere in the Lord’s Prayer do we find the words "me" or "mine" or "I".
In the beginning of the era of modern philosophy in the early seventeenth century, the philosopher Descartes put forward his famous dictum, "Cogito ergo sum"—"I think therefore I am." And following that model, a great deal of discussion of human personhood since then has centered round the notion of self-awareness, self-consciousness. But the difficulty of that model is that it doesn’t bring in the element of relationship. So instead of saying "Cogito ergo sum—I think therefore I am," ought we not as Christians who believe in the Trinity to say, "Amo ergo sum"—"I love therefore I am"? And still more, ought we not to say, "Amor ergo sum"—"I am loved therefore I am"?
