Why do some churches such as the Roman Catholic ones have images of Jesus, Mary and Joesph?

The first commandment that Moses wrote down which God commanded him to write clearly indcated that " ' Thou shall not make any graven images of me (God) or of the sea or of the underworld.' " Why does the Roman Catholic church makes images and statues and tinted windows which shiny colours and why do they call the priest ' Father.' Why? I also went to a Roman Catholic school but all of these teachings and doing seem to be in contradiction with the teachings of the Holy Bible.
