Dear Kevin, the human mind can never discern "absolute truth."  It can collectively grow and develop with new discoveries of truth in each and every generation as we listen to the Spirit in all of us.  The claim of infallible or absolute truth is an impossible goal for a fallible single or collective mind as if we compare our fallible minds to that of the infinite it would be similar to comparing an ant's mind to our own.  Yes there is suffering in this life but it may or may not lead to more or less truth...
