From Matins today, from a sermon by Saint Gregory Nazianzen

Such was the prelude to our friendship, the kindling of that flame that was to bind us together. In this way we began to feel affection for each other. When, in the course of time, we acknowledged our friendship and recognized that our ambition was a life of true wisdom, we became everything to each other: we shared the same lodging, the same table, the same desires, the same goal. Our love for each other grew daily warmer and deeper.

The same hope inspired us: the pursuit of learning. This is an ambition especially subject to envy. Yet between us there was no envy. On the contrary, we made capital out of our rivalry. Our rivalry consisted, not in seeking the first place for oneself but in yielding it to the other, for we each looked on the other’s success as his own.
