From today’s readings: “But you are a chosen race, a royal priesthood, a holy nation, God’s own people, in order that you may proclaim the mighty acts of him who called you out of darkness into his marvelous light” (1 Pet. 2:9).

So on this Earth Day here’s St. Basil the Great’s Prayer of Compassion

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 live.
