"The names of worldly things are utterly deceptive, for they turn the heart from what is real to what is unreal. Whoever hears the word god thinks not of what is real but rather of what is unreal. So also with the words father, son, holy spirit, life, light, resurrection, church, and all the rest, people do not think of what is real but of what is unreal, [though] the words refer to what is real. The words [that are] heard belong to this world. [Do not be] deceived. If words belonged to the eternal realm, they would never be pronounced in this world, nor would they designate worldly things. They would refer to what is in the eternal realm."
