How is god adressed in the middle ages?!!!! O_o

I think that in middle ages God was adressed as a super powerfull omnipresent god that chose the fate of all the people un the universe.
The people can´t doub the existence of God or any of his incredible powers or his hability of be invicible, be everywhere, make effect in everything, make people pay diesmos, and make our lives miserable T_T . And if you doub about all those strange and incoherent things, the church said that you are a witch, demon or other invented things, and then burn you like a giant meat skewer, and do not put vejetales, only you!!! XD

well, what I mean is that at that time could not choose to believe or not believe, you have to believe in God or you die, even if you not understand what is God.

and they need a explain to all the things that they can´t discover or understand.
they think that God create everything because they not have idea of what happened realy or how something like animals have life.
