Hi Phizzy, I was reading a dreadful book "Foxes Book of Martyers", I did not know that Five Million Christians were slaughtered by the Roman Empire. JW Elders use to tell me that I could not trust "Foxes Book" but I think there is some good information in it. The following paragraphs explain why he made the official edict, he was a Christian and saw the massive growth and potential of the Christian.
Here's a link I found interesting "http://www.unrv.com/culture/christianity.php
The Might Two: "Constantine and Licinius" had different views how to handle the Christian Population, Licinius was getting bad-luck it seems with his poor choices well Constantine appeared to be blessed (Just my opinion).
"Perhaps in order to lure Constantine into a final battle, Licinius began inciting Pagans against Constantine's edict which favored Christianity and championed a Pagan cause. By 324 AD, the conflict and rivalry came to a head. Constantine defeated Licinius in battles at Adrianople and Chrysopolis, which ended in Licinius' capture and execution."
After Constantine's death in 337 AD, his son Constantine II held a tolerant, if not supportive view of the ancient Pagan faith. His second son, Constantius, was a brutal supporter of Arianism. Constans, the third son, was also a Christian, but adhered to strict Orthodoxy. A rift between sects of Christianity developed, as well as a struggle for supreme power among the brothers, causing much political instability. Constantine II was killed only a few years after his father, and the remaining brothers settled in to continue the advance of Christianity. During their reigns many anti-Pagan laws were put into place. Constans dealt with dissent in a particularly brutal fashion. The forcible expansion of Christianity on the populace, which was now quickly becoming a part of the every day social fabric, also brought a great of resentment from some. Julian the Apostate (so named later for his pro-Pagan stance) came to power upon the death of Constantius and attempted, in vain to stem the tide of Christian advancement.
Julian attempted to bring back the ancient religion to the people of the Roman world, but Christianity had become too deeply ingrained. He removed various advantages that Christian priests and churches had enjoyed since Constantine and bestowed them upon Pagans instead. Christian teachers were also removed from their occupations in many cases. Though, for the most part he avoided open violence against the Christians, he did encourage the growth of non Catholic or Orthodox sects. The fight, which could be brutal at times, for religious supremacy evolved between these various factions, but Paganism was a dying part of the dominant culture. Even temples re-established by Julian were simply overrun by fanatic Christian mobs. Despite Julian's efforts, hindered by his short reign of 2 years, Paganism continued on the path to virtual extinction.
The final death knell of the Pagan faith came only a generation later, under the rule of Theodosius. An ardent Christian, and recognizing the amazing growth of the still relatively young faith, Theodosius and his western counterpart Gratian, recognized Christianity as the official religion of the Empire in 380 AD. Gratian too, likely at the partial behest of Theodosius refused the title of Pontifex Maximus (head priest) and it was bestowed instead on the Catholic Pope in Rome. Severe punishments for Pagan, and especially 'heretic' Arianism were enforced and the established Churched prospered. In 390 AD, a massacre ordered by the Emperor of 7,000 people who revolted in Thessalonica resulted in his own 8 month penance. By the beginning of the 5th century, after just 400 years, the Church grew from a fledgling mystery cult into a power on nearly equal terms with the Roman Emperor himself. Though there would still be much work to be done, especially among Germanic tribes and in places such as Britain, Christianity would slowly come to dominate the entire western world."
