The saintess is twisted and isn't even talking to God its just her own perverse thinking. Even if it is the voice of God its only one of them since the Goddess of Love revived him and made him able to do all hes doing just to be with him.
Oh golly, so it all began to twist from the priestess..ahaha
Ironic, isn't it^^ He gained power from the goddess herself so nobody can harm him~
Aaah, I'm having a blast with this super f*cked up series! uwu
