Roman emperors Gratian and Theodosius I issue a decree that actresses must be permitted to give up their jobs for religious reasons.
However, if they are discovered leading unchaste lives after leaving the theater, they will be forced to return to being an actress and won't be allowed to leave again.
According to this new Roman law:
"If a woman of the stage asks to be released in the name of religion, this must not be denied her. If she is later involved in indecent acts and found to have betrayed the religion which she adopted, and if she continues with the profession that she had officially abandoned and remains an actress in spirit, then she must be taken back to the stage.
There she must remain, without any hope of absolution, until she becomes a ridiculous old woman who ugly with old age, she cannot even then receive absolution despite the fact that she cannot then be anything but than chaste." [CTh 15.7.8]
In Rome, being an actress is not a respectable profession: on the contrary, performing on stage is akin to prostitution. Acting might not involve sex, but from the Roman perspective it is still a form of selling one's body to the public for the purpose of entertaining them.
Thus working in the theater places a person in the lowest social classes. A Christian, however, is allowed to escape both the profession and the negative reputation that comes along with it. No such dispensation is granted to Jews and pagans.
