How did Theodosius I’s policy toward pagan religions change in 391?

In 391, Theodosius I significantly intensified his religious policy toward paganism. Prior to this year, he had generally tolerated pagan practices and continued to appoint adherents of the old cults to high government offices.

In February 391, however, Theodosius issued a decree that prohibited the performance of sacrifices and the visiting of temples. This shift marked a move toward stronger enforcement against pagan religions, building upon the religious policy he had pursued since 380. By November 392, he further escalated these measures by completely prohibiting the worship of pagan gods, leaving no doubt regarding his stance against the traditional cults.123
