A great deal of things occurred after the crucifixion of Jesus and before the first Council of Nicaea in antiquity that helped to define Christianity and the Christian conception of God. These other philosophies include Gnosticism, Adoptionism, Marchionism, Montanism, and several other permutations in terms of theology. Declaring these other philosophies to be heresy was something that the first Council of Nicaea accomplished and that was an action that was part of the purpose of the first Council of Nicaea, which was otherwise known as the First Ecumenical Council. The First Ecumenical Council didn’t take place in order to tell people what they could and could not believe in terms of the nature of Christ in relation to the Christian concept of God; however, there were a lot of different ideas that people had after the crucifixion of Christ that developed over a significant period of time, and a significant number of disagreements existed in regards to the true nature of Christ as well as what his exact relationship to God was. The first Council of Nicaea was allowed to take place during ancient Roman times in order to resolve these issues and to bring definition to a religion that, at least at the time, was conflicted as to what the substance that it was made of in terms of religious theology would be.
Something else that the First Council of Nicaea did was make Christianity’s celebration of the holiday commonly known as Easter into a celebration that was a thing that was different from the Jewish celebration of the same holiday. The first Ecumenical Council separated the Christian Easter by making it a holiday that would depend on calculations made on the Christian calendar. Ancient Christian leadership decided that their Easter would still be on a Sunday, but those who held positions of authority within the Christianity of that era decided that their Easter wouldn’t necessarily have to be on the same day as the Jewish Easter; however, for the quaint, antiquated, Christians leaders of Ancient Rome, if it just so happened that their Easter decided to fall on the same day as the Jewish Easter during one particular year or another, their decision was that it would be not necessarily be bad, that it would be permissible, and that it would be okay with them. Regardless of any disputes as to what might have been precisely the exact, perfectly historically correct, theologically proven right time for the Easter bunny with the painted eggs to make his or her appearance, ancient Christian leadership was in agreement with the concept that Jesus rose on the third day, and the Christians of antiquity in ancient Roman times celebrated Easter out of reverence for what they believed was the divinity of Jesus and the closely related deity whom they considered to be God. According to Steven Runciman, “The Seven Eecumenical Councils were considered, along with the Holy Scriptures, to be the basis of the Orthodox faith. Each had been convened to settle some particular point of theology and pronounce against some particular heresy. The doctrine of the Trinity is a difficult doctrine and the doctrine of the Incarnation makes it no easier. The path of correct Christology was very narrow, and even the best-intentioned theologian might slip to one side or the other. Christianity had triumphed over paganism in the midst of one of her own civil wars when the Ariansby denvying the full divinity of Christ, were trying to establish a more unitarian concepton of the Godhead”.
In terms of the divinity of Jesus and the authentic nature of God, both were subjects that many different early Christian believers had differing ideas about. The concepts relating to the trinity which modern believers know of today are the ideas that prevail in the current era, but that wasn’t the case in older Roman times during ages of antiquity. Ideas like Arianism and Modalism questioned a great deal of the theological beliefs that modern Christian believers take for granted. The divine nature and divine origins of Jesus were some of what beliefs that were later recognized as heresies, such as Arianism and Modalism, questioned. The mainstream Christian conception of God and the relationship Jesus had with God were other Christian ideas that ancient beliefs that were eventually declared to be heresies were contentious with. The First Ecumenical Council helped to cement ideas regarding the trinity into place and give support to the idea of the trinity as the true nature of the godhead in terms of Christian theological reasoning. Early Christian history was a time when ancient believers were not only persecuted for a long time before being granted support by Constantine I, but it was also a time when Christians had some arguments amongst themselves in terms of their religion. Early Christians were asking themselves who their God really was, whether or not Jesus was really divine in nature, and how to make sense of it all.
A assortment of disparate events occurred between the crucifixion of Jesus and the First Council of Nicaea that shows those who might exist in modern times who take the time to look back on history what went into the creation of the Christian concept of God why the Christian conception of God is what it is today. The majority of what happened with regards to Christianity in Ancient Roman times had to do with the exchange of beliefs, concepts, and ideas in relation to what beliefs were permitted, which ones were persecuted or looked down upon, how long-held beliefs changes, and how certain ideas were perceived. The concept of the trinity was the thought that prevailed, but the journey towards the realization of the trinity as the belief which ended up being the idea supported by the majority is what is fascinating to gaze at in terms of the ancient historical context of the development of the godhead.
