The Truth about Schizophrenia
Schizophrenia is temporal punishment due to sin. Although, the Catholic Church views schizophrenia as the same mental illness described by psychiatry, they would have to discern whether a person is undergoing temporal punishment on an individual basis. I believe that schizophrenia is always temporal punishment and that the church has been misled by psychiatry.
The Catechism of the Catholic Church on temporal punishment is as follows:
Temporal punishment is purification of the unhealthy attachment to creatures, which is a consequence of sin that perdues even after death. We must be purified either during our earthly life through prayer and a conversion which comes from fervent charity (love for God & neighbor), or after death in purgatory.
Every sin, even venial, entails an unhealthy attachment to creatures, which must be purified either here on earth, or after death in a state called purgatory. This purification frees one from what is called the "temporal punishment" of sin. This punishment must not be conceived as kind of vengeance inflicted by God from without, but as following from the very nature of sin. A conversion which proceeds from a fervent charity can attain the complete purification of the sinner in such a way that no punishment would remain.
The forgiveness of sin and restoration of communion with God entail the remission of the eternal punishment of sin, but temporal punishment of sin still remains. While patiently bearing sufferings and trials of all kinds and, when the day comes, serenely facing death, the Christian must strive to accept this temporal punishment of sin as a grace. He should strive by works of mercy and charity, as well as by prayer and the various practices of penance, to put off completely the "old man" and to put on the "new man".
This is the best material I can find for the Christian who has been diagnosed with schizophrenia.
Therein lies the problem.
