People often say that humans have always eaten animals, as if this is a justification for continuing the practice. According to this logic, we should not try to prevent people from murdering other people, since this has also been done since the earliest of times.
Cruelty to dumb animals is one of the distinguishing vices of low and base minds. Wherever it is found, it is a certain mark of ignorance and meanness; a mark which all the external advantages of wealth, splendour, and nobility, cannot obliterate. It is consistent neither with learning nor true civility.
A good deed done to an animal is as meritorious as a good deed done to a human being, while an act of cruelty to an animal is a bad as an act of cruelty to a human being.
Killing animals for sport, for pleasure, for adventure, and for hides and furs is a phenomena which is at once disgusting and distressing. There is no justification in indulging in such acts of brutality.
Animals are God's creatures, not human property, nor utilities, nor resources, nor commodities, but precious beings in God's sight. …Christians whose eyes are fixed on the awfulness of crucifixion are in a special position to understand the awfulness of innocent suffering. The Cross of Christ is God's absolute identification with the weak, the powerless, and the vulnerable, but most of all with unprotected, undefended, innocent suffering.
