Today is the feast of St. Basil the Great of Caesarea, Doctor of the Church, and of St. Gregory of Nazianzus, Doctor of the Church.
From Basil's Homilies on the Hexaemeron (Homily IX):
The dog is not gifted with a share of reason; but with him instinct has the power of reason. The dog has learned by nature the secret of elaborate inferences, which sages of the world, after long years of study, have hardly been able to disentangle. When the dog is on the track of game, if he sees it divide in different directions, he examines these different paths, and speech alone fails him to announce his reasoning. The creature, he says, is gone here or there or in another direction. It is neither here nor there; it is therefore in the third direction. And thus, neglecting the false tracks, he discovers the true one. What more is done by those who, gravely occupied in demonstrating theories, trace lines upon the dust and reject two propositions to show that the third is the true one?
Does not the gratitude of the dog shame all who are ungrateful to their benefactors? Many are said to have fallen dead by their murdered masters in lonely places. Others, when a crime has just been committed, have led those who were searching for the murderers, and have caused the criminals to be brought to justice. What will those say who, not content with not loving the Master who has created them and nourished them, have for their friends men whose mouth attacks the Lord, sitting at the same table with them, and, while partaking of their food, blaspheme Him who has given it to them?
From Gregory's Funderal Oration for Basil (Oration 43):
He indeed could neither rain bread from heaven by prayer, to nourish an escaped people in the wilderness, nor supply fountains of food without cost from the depth of vessels which are filled by being emptied, and so, by an amazing return for her hospitality, support one who supported him; nor feed thousands of men with five loaves whose very fragments were a further supply for many tables. These were the works of Moses and Elijah, and my God, from Whom they too derived their power. Perhaps also they were characteristic of their time and its circumstances: since signs are for unbelievers not for those who believe. But he did devise and execute with the same faith things which correspond to them, and tend in the same direction. For by his word and advice he opened the stores of those who possessed them, and so, according to the Scripture dealt food to the hungry, and satisfied the poor with bread, and fed them in the time of dearth, and filled the hungry souls with good things. And in what way? For this is no slight addition to his praise. He gathered together the victims of the famine with some who were but slightly recovering from it, men and women, infants, old men, every age which was in distress, and obtaining contributions of all sorts of food which can relieve famine, set before them basins of soup and such meat as was found preserved among us, on which the poor live. Then, imitating the ministry of Christ, Who, girded with a towel, did not disdain to wash the disciples' feet, using for this purpose the aid of his own servants, and also of his fellow servants, he attended to the bodies and souls of those who needed it, combining personal respect with the supply of their necessity, and so giving them a double relief.
