Like any religion or world view, Christianity provided both benefits and harm to the Roman Empire. Had the new religion remained separate from state, its benefits would no doubt have far outweighed the detriment. However, its adoption as the religion of state, first by Constantine and eventually by Theodosius, is considered to have hastened the decline of the Empire.
Christianity was endorsed by by all the emperor after Constantine (who also favoured it) but one. The Edict of Thessalonica of 380, issued by the co-emperos Gratian and Theodosius made mainstream Chtistianoty the state religion. The Latin and Greek Churches, which later came to be called Catholic and Orthodox respectively) the sole legitimate religion of the empire.The object of the edict was to ban the many dissident Christian doctrines which were branded heretic. The main target was Arian Christianity, which was popular around the empire and which was persecuted. Thus, the edict also promoted greater uniformity among the Christians.
Theodosius also ppersecuted pagan religions. he introduced laws which banned the institutions and practices of Roman religion which had not already been banned by previous Christian emperors. This made practicing this religion virtually fully illegal. Theodosius either ordered the destruction of pagan temples, shrines and statues or condoned such destructions by Christian monks and zealots. In some parts of the empire there were also forced conversions. These persecutions weakened pagan religions and further favoured the spread of Christianity.
After eliminating competing religions such as of Mithras and Isis by slaughter, destruction of temples and absorption, it established a dominance which acted as both a unifying force and as a suppressive one, which lasted until the Renaissance began the long road to rational assessment of human relationships. It also acted as a buttress against the rampant spread of Islamic invaders through Europe.
There was only one Roman Empire. Moreover, the Roman Empire did not study Christianity. An empire cannot study. The Roman Empire was where Christianity spread from Judea (which was a part of the Roman province of Syria). Both Catholic and Orthodox Christianity developed in the Roman Empire. Originally the were called Latin or Western Christianity and Greek or Eastern Christianity respectively. The former was the dominant form of Christianity in the western part of the Roman Empire and the latter was the dominant form of Christianity in the eastern part of this empire. There were also dissident Christian doctrines and sects.
The emperor Theodosius I declared Christianity to be the official religion of the Roman empire. In fact, he made Christianity mandatory for all.
Christianity did not easily spread through the Roman Empire. See the related question, "How did Christianity spread throughout the Roman Empire?"
Christianity developed from a religion among a small group of Jews (who lived in Judea, which was part of the Roman Empire) into a mass religion in the Roman days. It spread around the Roman Empire. It became state religion. Catholic Christianity and Orthodox Christianity developed during the Later Roman Empire. They were originally called Latin or Western Christianity and Greek or Eastern Christianity respectively. The former was the main form of Christianity in the western part of the Roman Empire and the latter was the main form of Christianity in the eastern part of the Roman Empire.
