Learning from his predecessors that divine assistance was necessary for aid more powerful than his military forces, Constantine, Caesar of the Western Roman Empire, set out in search of a god whom he could count on for their protection and assistance. After having a vision of a "trophy of a cross of light in the heavens, above the sun, bearing the inscription: Overcome by this", he claimed that these were not the pagan gods but rather “God, the only Son of the one and only God.” » He therefore decided to devote himself to reading the Bible. Leading his army with his new allegiance to the Christian God, Constantine became the sole emperor of the Roman Empire. In 313, he issued the Edict of Tolerance, putting an end to the persecution of Christians. Although Constantine's conquest of the Roman Empire appeared to be a positive event for Christianity, the original biblical canon of Christianity manifested itself in a liberal faith doctrine devoid of the true devotion of a true disciple. Eusebius's Life of Constantine, the first written record of Constantine's history in the 4th century, expressed Constantine's gratifying victories sanctioned by the power of God. Eusebius describes the reign of Maxentius, who "took great pains in impiety and wickedness, to venture without hesitation into every vile and impure action." He separated women from their husbands, shaming them for responding to his desires. He participated in the massacre of countless Roman citizens in their own city. He mistreated and slaughtered women, children and animals as a means of comfort and victory. Constantine, “filled with compassion for all these miseries”, defeats the tyrannical reign of Maxentius. Rome praised Constantine as having senator-like authority, thus losing its religious sentiment. Constantine's conversion of the Roman Empire had a lasting effect on Christianity. Eusebius represents conversion as a noble and respectable event for Christianity; However, the early Christians knew that the true beliefs of Christianity had been greatly shaken. Because Christianity lost its true foundation, Christians were forced to find new ways to practice their beliefs and express their devotion. This watered down version of Christianity opened the door to various divisions within the Church that still exist today. Although Constantine's conquest of the Roman Empire appeared to be a positive event for Christianity, the original biblical canon of Christianity manifested itself in a liberal religion lacking the true devotion of a true disciple.
