He allowed to his Christian subjects the free exercise of their religion, permitted them to build churches, elect bishops, and conduct services at their pleasure, and even suffered them to bury their dead, though such pollution of the earth was accounted sacrilegious by the Zoroastrians.

No unworthy compliances with the established cult were required of them.
Proselytism, however, was not allowed; and all Christian sects were perhaps not viewed with equal favor.

Chosroes, at any rate, is accused of persecuting the Catholics and the Monophysites, and compelling them to join the Nestorians, who formed the predominant sect in his dominions.

Conformity, however, in things outward, is compatible with a wide diversity of opinion; and Chosroes, while he disliked differences of practice, seems certainly to have encouraged, at least in his earlier years, a freedom of discussion in religious matters which must have tended to shake the hereditary faith of his subjects.

He also gave on one occasion a very remarkable indication of liberal and tolerant views.
When he made his first peace with Rome, the article on which he insisted the most was one whereby the free profession of their known opinions and tenets in their own country was secured to the seven Grecian sages who had found at his court, in their hour of need, a refuge from persecution.
In his domestic relations Chosroes was unfortunate.
