Many indeed are the wondrous happenings of that time: God hanging from a cross, the sun made dark and again flaming out; for it was fitting that creation should mourn with its creator. The temple veil rent, blood and water flowing from his side: the one as from a man, the other as from what was above man; the earth shaken, the rocks shattered because of the rock; the dead risen to bear witness to the final and universal resurrection of the dead. The happenings at the sepulcher and after the sepulcher, who can fittingly recount them? Yet no one of them can be compared to the miracle of my salvation. A few drops of blood renew the whole world, and do for all men what the rennet does for the milk: joining us and binding us together.
Gregory of Nazianzus, On the Holy Pasch
The love of God is not taught. No one has taught us to enjoy the light or to be attached to life more than anything else. And no one has taught us to love the two people who brought us into the world and educated us. Which is all the more reason to believe that we did not learn to love God as a result of outside instruction. In the very nature of every human being has been sown the seed of the ability to love. You and I ought to welcome this seed, cultivate it carefully, nourish it attentively and foster its growth by going to the school of God's commandments with help of His grace.
