Schizophrenia is a clinical diagnosis. It is made on a scale and based on thresholds both for specificly exhibited behaviors and aggregate number of behaviors exceeding the threshold. In other words, a person could exhibit several behaviors consistent with schizophrenia but not meet the clinical definition.

E.g. clinical science does not pathologize people who claim to hear god during prayer and admit acting upon what they heard when the claims are in the context of organized religious practice and the behavior does not disturb the peace too much.
