Who's handling the biblical mandate to take the Gospel to dogs and cats?
I know your point was to ridicule the Word of God, but for others who are interested, words have context, and specific usages of words are properly determined by their own contexts. There is a very interesting reason that the word CREATURE is used, having to do with the affects of the Gospel of Christ, not only on men, but on the redeemed sons of God, AS WELL AS the entire creation. The subject is found in Romans chapters 8 and 9, and other places. CREATURES, in the Scriptures, also refer to living beings in the heavens (the spirit world) and in Heaven itself.
So, I take it you are not a Bible reader, and are not familiar with the way biblical expressions are used within their own contexts.
