Two prayers for animals attributed to St Basil:
O God, enlarge within us the sense of fellowship with all living things, our brothers the animals to whom Thou gavest the earth as their home in common with us. We remember with shame that in the past we have exercised the high dominion of man with ruthless cruelty so that the voice of the earth, which should have gone up to Thee in song has been a groan of travail. May we realize that they live not for us alone, but for themselves and for Thee and that they love the sweetness of life even as we, and serve Thee better in their place than we in ours.
For those, O Lord, the humble beasts, that bear with us the burden and heat of day, and offer their guileless lives for the well-being of mankind; and for the wild creatures, whom Thou hast made wise, strong, and beautiful, we supplicate for them Thy great tenderness of heart, for Thou hast promised to save both man and beast, and great is Thy loving kindness, O Master, Saviour of the world.
I especially like the line "[they] serve Thee better in their place than we in ours." So humbling.
