Understanding the early theological struggles of the Christian church is vital to understanding history. This series will focus on Rome and the political and religious forces that drove various interpretations of Christ and his teachings - and a push towards orthodoxy. Disclaimer: This series is intended for students, to give them a broad overview of a complicated subject that has driven world history for centuries. Our story begins and focuses on Rome. One of the toughest questions early Christians had to face was Mosaic Law. Did the laws of Moses still apply, or did the teachings of Jesus Christ replace them? The issue of circumcision became a focal point for this conflict. In an era without surgical anaesthetic or procedures, asking grown men to have their foreskins removed was a painful process. Paul the Apostle argued vehemently against the practice because he believed that Christianity needed to be accessible to Romans, the gentiles, and he knew that requirements like circumcision would vastly reduce the number of people willing to convert. Gradually, Judaizing forces were pushed out of mainstream Christianity as the religion began to convert more Romans. But it soon faced another crisis: what was the nature of Christ? This issue would come up time and time again, but one of the earliest conflicts over it came from the Docetists. They believed Christ was a being of pure spirit, and that it would denigrate his godhood to consider him a human man. But in the Epistles, John argued fervently against that idea, saying that Christians must believe in Christ "in the flesh" in order for his sacrifices to be meaningful. A bishop named Ignatius of Antioch embraced that idea when facing a conviction to be thrown to lions in the Colossuem, believing that his martyrdom echoed Christ's and he was proud to give his body to prove his faith. Then the 3rd Century Crisis hit, and the Roman government fell apart. The Church stepped in, and many people believed its prophesie

Constantine had restored full rights to Christians in the Roman Empire with the Edict of Milan, but he did not expect theological debates to divide the church. Conflict between the orthodox church and both the Donatists and the Arians drew him to intervene. Disclaimer: This series is intended for students, to give them a broad overview of a complicated subject that has driven world history for centuries. Our story begins and focuses on Rome. Constantine had gained control of the Roman Empire, its first Christian emperor, and he restored full rights to people of the Christian faith with the Edict of Milan. But his generosity immediately raised a question: what did the church do with so-called traditors, who had renounced the Christian faith during the days of persecution and now wanted to return? The Roman Church demanded they be restored, because the doctrine of penance declared that anyone could repent for any sin, no matter how grievous. But in North Africa, one group was outraged when a traditor named Caecilian was not only restored to the faith but elected Bishop of Carthage. They refused to accept him and elected their own bishop, Donatus, instead. Donatus performed the role of a bishop without official church authority and he insisted on re-baptizing traditors in contradiction to the doctrine of penance. The church wanted to put him on trial, but since Donatus had rebelled against the people calling for his trial, he didn't believe it would be a fair trial. He wrote Constantine asking for help and the emperor decided to intervene, setting a dangerous precedent for imperial involvement in affairs of the church. Over a series of several trials, church leaders continued to condemn Donatus and he continued to ask Constantine for retrials until the emperor grew fed up and washed his hands of the matter. The unrepentant Donatists went on to become a splinter church that divided North Africa for centuries. Around the same time, a bishop named Arius had begun to

The Council of Nicaea convened to decide the guiding rules of the church - and to resolve the questions posed by Arian theology. A deacon named Athanasius set himself against Arius and succeeded in getting his teachings declared heresy. Disclaimer: This series is intended for students, to give them a broad overview of a complicated subject that has driven world history for centuries. Our story begins and focuses on Rome. Constantine called the Council of Nicaea not only to address the teachings of Arius, but also to decide basic matters for how the church would go forward. Yet it was the debate over Arian theology which quickly came to dominate the council's time. The bishops effectively split into two factions, one backing Arius and the other led by a deacon named Athanasius. Athanasius vehemently opposed the Arian teachings and would not allow any compromise to be formed with the other group. Yet he played the politics very carefully, adopting in his own arguments the phrase "homoousian" (or "of the same substance") to describe the relationship between the Father and the Son, knowing full well that Arius would never accept an agreement which included this idea. Even when others tried to compromise with the phrase "homoiousian" (or "of similar substance"), Arius would not agree. Athanasius used the extra time to make private deals and assemble a majority coalition, with which he successfully caused Arianism to be declared heresy and forced Arius himself into exile. Emperor Constantine was just happy a decision had been reached, but a bishop in his own court would not let matters rest so easily. This bishop, Eusebius, campaigned tirelessly for the restoration of Arius and managed to get Athanasius exiled instead. Constantine himself wound up being baptized by Eusebius, and his son Emperor Constantius II would be a die-hard Arian in his turn. Eusebius even ordained a Goth named Ulfilas to preach to the Gothic tribes, and his sucess meant that the tribes became

The Council of Ephesus meant to heal a rift between Nestorius of Constantinople and Cyril of Alexandria, but instead it set off a chain of ecumenical councils that disagreed with each other, excommunicated rivals, and ultimately led to more factions within the church. Disclaimer: This series is intended for students, to give them a broad overview of a complicated subject that has driven world history for centuries. Our story begins and focuses on the Romane Empire. A centuary after Constantine, the Emperor Theodosius II found himself wrapped up in yet more theological disputes. His chosen patriarch of Constantinople, Archbishop Nestorius, had angered many other church leaders with his teachings that Christ had separate human and divine natures. Cyril of Alexandria wrote to the Pope in Rome for support against Nestorius, and received permission to excommunicate him. Nestorius responded by having the emperor call an ecumenical council, at which he intended to excommunicate Cyril. But Cyril acted first, declaring for the excommunication of Nestorius and forming a majority by pushing the council to begin early before the supporters of Nestorius could gather. When they did, they formed their own council and excommunicated Cyril right back, only to be excommunicated in turn by Cyril's Council of Ephesus. Theodosius II attempted to resolve this by calling a second council, but this time none of the Western delegates had time to arrive and in their absence, monophysite leaders from the East excommunicated Nestorius again and declared monophysitism the official doctrine of the church. Those who didn't get to participate called this the Robbers Council and refused to acknowledge it. Then Theodosius II died, and this fight devolved onto his successor, Marcian. Marcian called together the Council of Chalcedon to rule on the previous councils, where it was finally decided that Christ had two unified natures, human and divine, and everyone who'd supported the Robbers Counci
