Agnostic: questions the existence of God, heaven etc. in the absense of material proof and in unwillingness to accept supernatural revelation. A person who believes that the human mind cannot know whether there is a God or an ultimate cause, or anything beyond material phenomenaAgnosticism: the doctrine of agnostics; distinguished from ATHEISMAtheism: the belief that there is no God, or denial that God or gods exist; godlessnessAtheist: A person who believes that there is no God.I thought that it was quite interesting that there is a distinct difference between atheist and agnostic and thought that others should see the contrast. It may help when we are speaking to those who claim to be without God. blessings
