Answer:
Yes, Jews were able to practice their religion.
Explanation:
For the Romans, religion was, above all, the fear of the supernatural. In Rome, religion had two aspects: one public, the state cult, and another private, the family worship. To understand the Roman religion it is important to understand that for them it did not imply the assumption of a philosophy, a moral and a program of life, but the participation in the rites. The religious man was the one who participated in the rite (not the believer), in this way it is explained that in Rome all the religions of the Empire were settled.
In the year 313 A.D., the <u>Edict of Milan</u> is published in the Roman Empire, which is the first legal document that establishes <u>religious freedom</u>. Indeed, Emperor Constantine comes to operate the reversal of the panorama of the relations between the Empire and the Christians. The Edict established freedom of worship for Christians and other religions, although in reality only the former saw their convictions threatened by the Empire. In any case, the Edict states that "no one who has accepted the Christian belief or any other that seems to be the most convenient for him, is obliged to deny his conviction."
