"So out of the ground the Lord God formed every beast of the field and every bird of the air, and brought them to the man to see what he would call them; and whatever the man called every living creature, that was its name. (Genesis 2:19)
The creation story reminds us of two important points. First, since the start, God has put the entire world into our care. Second, stewardship has been around since the beginning of mankind, it isn't something recently invented by the Church. Just as past generations built our Church, it is now our responsibility to continue to nurture and develop these gifts for future generations.
