Technically, the role of a prison is to hold people convicted of crimes, whose sentence has stipulated that they must be incarcerated.
In the big picture, prisons serve several purposes:
Obviously, not all prison serve the same purpose, and the amount of each that goes on in a specific prison varies widely.
Note, that in the US, a "prison" is different than a "jail". Prisons are generally run by the State or Federal authorities, and function for the purposes above. Jails are almost exclusively run by local authorities (city, town, or county), and serve as short-term detention: places where people who are arrested are held prior to a formal hearing where charges are levied. Jails generally don't hold people for more than a couple of days at most; those needing to be held longer are transferred to an appropriate prison. Another noted difference is that jails are almost always immediately adjacent to the relevant courthouse, while prisons tend to be in isolated places.
Prisons have several roles such as locking up people that have committed a crime, so as to protect the community from further crimes that a person might commit. Another function is to "rehabilitate" offenders so as to prevent a person committing similar crimes in the future. About 75% of prisoners have drug addiction as a comorbid condition to heir offences. Most drug addicts return to prison after release, because drug addiction is very difficult to treat. Recidivism (repeat offences) is rife, because people do not seem to understand that for instance drug addiction is a disease, not a "psychological" problem although the illness have "psychological" symptoms.

Religion does not have an official role in the criminal justice system. However, religious beliefs can influence individuals' decisions and actions, including those related to crime and justice. Additionally, some prisons may provide accommodations for religious practices and offer programs that incorporate religious teachings as part of the rehabilitation and reintegration process.

Private security systems provide the exact same services as local state/county systems, but charge all the government agencies for the service. They have their own jails/prisons, transport services and guards.
