What is the difference between a truth and a belief?

Many people believe in the existence of a personal God in whose image we are made. Is there a truth about that belief? That is, regardless of differing beliefs, is it either true for the universe (and therefore for all of humanity) or false ( and therefore for all humanity) that such a God exists? Do you believe in the concept of truth which holds that there is a reality about the things of the universe that we may not agree upon, but nevertheless those uncertain things either are or are not true, regardless of what we believe? If you do believe in truth that way, then is the existence of such a God an important question to pursue?

To pursue critical thinking rationally presupposes a reality about the universe which is independent of our preferences, wishes, or beliefs. --T.Butler


"A certain circumspection with regard to any claim to truth is entirely appropriate. But it ought not to lead us as far as dropping all claims to truth. That leaves us merely blundering about among various types of tradition……we must regard circumspection as a serious obligation with respect to any claim to truth, but we must also have the courage not to lose hold of the truth, to stretch toward it and to accept it humbly and thankfully, whenever it is given to us." --Joseph Ratzinger

"There is a dichotomy between what we are and what we do; and this creates an inclination toward a certain muddiness of spirit that Jean-Paul Sartre terms 'bad faith.' We are often guilty of hiding the truth from ourselves-or hiding ourselves from the truth."--Michael Casey, monk of Tarrawarra

"People make things up to make themselves believe what they want to be true."--a CRE 101 student. (That's the fallacy known as Wishful Thinking.)
