Basic Law, Article 4, para. 1

Freedom of faith and of conscience and freedom to profess a religious or philosophical creed shall be inviolable.

NRW State Constitution, Art. 20

Churches and religious communities have the right to conduct worship services and provide pastoral care in educational institutions, hospitals, penitentiaries and similar public institutions, but without any form of coercion. 

Humans are unique in that they believe, profess their beliefs, and engage in ritual practices. German constitutional law ensures that individuals can exercise their freedom of faith regardless of whether that person is free or incarcerated.
