To be more honest, he was the father of Big Bang Creationism. The idea that our universe is expanding from a very small single source is his idea. Others, later, postulated that the beginning could have started from an area much smaller than an atom, some even postulating from "nothing." Now if that isn't creationism of a new sort I don't know what is.
The cosmological redshift should be thought of as a distance only effect, just as Edwin Hubble believed as the best explanation of the data.
