Roy, this may be news to you, but the Old Testament was written in Hebrew, not English. The Hebrew word for dominion is "radah", which literally means "to rule over with authority".
The Scripture says God has given man this temporal rule:
The earth is under man's temporal ownership. Temporal, because the eternal and final owner of land is the Creator. But He has titled man with this temporal ownership by "putting all things under" man's feet.Psalm 8:4-6
"What is man, that you are mindful of him? and the son of man, that you visit him? For you have made him (man) a little lower than the angels, and have crowned him with glory and honor. You made him (man) to have dominion over the works of your hands; you have put all things under his feet:"
You should listen to the mp3's and read the article I posted. You aren't afraid of reading an alternative view of things, are you?
