3. First Ecumenical Council - Council of Nicea, 325
The divinity of Christ as an eternal being officially became orthodoxy at the Council of Nicea in 325, the First Ecumenical Council. Its immediate effect was to condemn Arianism. Arius asserted that Christ was a created being, which ultimately put the worship of Christ as divine in jeopardy (Gonzalez, 2010, Vol. 1, Kindle Locations 3311-3326). Prior to this council, the church did not have an official position on the issue. Coming out of this important council was the terminology describing God the Father and Jesus Christ as "one substance" or "homoousios", a word that was suggested by Constantine (3390-3402). This terminology was later used when officially defining Trinitarian doctrine at the also important Second Ecumenical Council (Stookey, SESSION 3: THE EARLY CHURCH: Imperial Christianity, 325-600). The Council of Nicea in 325, called for by Constantine, was also part of the beginnings of the state using its power to force a unified system of beliefs among Christian citizens (3271-3278). That theme would continue for many centuries and become the cause of significant bloodshed and political turmoil, particularly in the Reformation era of the sixteenth and seventeenth centuries (i.e. the Thirty Years War). It also provided us the basis of what is today called the Nicene Creed; recognized as the “most universally accepted Christian creed” (3403-3404).4. Second Ecumenical Council - I Constantinople, 381
The Trinitarian doctrine of God as three persons of one substance, previously discussed at the Council of Nicea, was officially ratified at the Second Ecumenical Council (Gonzalez, 2010, Vol. 1, Kindle Locations 3656-3662). Since then, the doctrine of the Trinity has been a major pillar in defining the boundaries of Christian orthodoxy. It is a belief shared by the Roman Catholic Church, the Eastern Orthodox Church, and mainstream Protestant churches alike. Groups like the present day Jehovah's Witnesses who deny this doctrine are widely considered by mainstream Christianity to be heretical cults.5. The Barbarian Invasions

6. The Great Schism
Tensions had been mounting for centuries when the Eastern and Western churches finally split in 1054 AD (Stookey, SESSION 4: MEDIEVAL CHRISTIANITY: Low Middle Ages, 600-1054). Disagreements included the method of baptism, the use of symbols/images, the worship of Mary, and finally, clerical celibacy. Prior to the Great Schism in the eleventh century, what were later called the Roman Catholic Church and the Eastern Orthodox Church were still unified as one universal ("catholic") church. Therefore, the Great Schism marked a major turning point for church unity. When it occurred in 1054 AD, first the West and then the East mutually excommunicated one another, and those declarations remained in place until 1965 (Stookey).7. Council of Clermont (1095) and The Crusades
It was at the Council of Clermont in 1095 that Pope Urban II called for what are now known as The Crusades. There were several goals of the Crusades including the recapture of Jerusalem and the rescue of the Eastern empire from the Muslims, and the reunification of the Eastern and Western churches, which had split only a matter of decades before the Council of Clermont (Gonzalez, 2010, Vol. 1, Kindle Locations 5837-5839). In the immediate term, the Crusades succeeded in bringing about all of these. However, in the final outcome, all that was gained was eventually lost. One could argue that the most significant, lasting effects are a grave black mark on the history of the church that is frequently cited by detractors and in polemics against the Christian religion, and an ongoing distrust between Muslims and Christians that continues to manifest itself in violence to this day.8. Luther's posting of the 95 Theses on the door of the castle church in Wittenburg
This event, which occurred on October 31, 1517, is commonly credited as the beginning of the Protestant Reformation (Gonzalez, 2010, Vol. 2, p. 28). In his 95 Theses, Luther attacked the sale of indulgences. He was responding specifically to the sale of full, plenary indulgences to pay for St. Peter's Cathedral (Stookey, SESSION 6: Renaissance & Reformation―Luther & Germany). The Protestant Reformation led to enormous reform within Christendom, beyond the Roman Catholic Church, and also within. Among the most significant results are the fundamental Protestant doctrines of sola fide (Faith Alone), sola gracia (Grace Alone), and sola scriptura (Scripture Alone).9. Thirty Years War (1618-1648)
The very blood and protracted Thirty Years War resulted in a backlash against religious zealotry. Its immediate outcome was a limited degree of religious tolerance (Stookey, SESSION 8: Reformation (cont.) & Counter-Reformation). More significantly, however, it marked the beginning of a decline in religious fervor. People began seeing religion as a private matter (Gonzalez, 2010, Vol. 2, p. 184). That thought process transitioned into the Enlightenment, and eventually toward the separation of church and state.10. Second Vatican Council (Vatican II) in 1965
Before Vatican II, the Roman Catholic Church responded to the new political, economic, and social changes of the modern era with extreme disapproval (Gonzalez, 2010, Vol. 2, p. 441) . Progressive theologians were censured by the Roman Catholic Church (Stookey, SESSION 13: Modern Christianity, 20th century). Vatican II marked the beginning of a new receptiveness to modern ideas. The immediate effects included permitting use of the vernacular languages and the adaption of liturgy as appropriate to meet the needs of various cultures (Gonzalez, p. 445). The longer term effects are still playing out, but they are virtually guaranteed by radical departures from the church’s historical positions on things like religious freedom, which was embraced at Vatican II (p. 446). This also includes toleration of those within the RCC who promote progressive ideas like Henri de Lubac, for example, who having previously been silenced, was assigned as a theological consultant for Vatican II (Gonzalez, p. 453), and later became a cardinal (Stookey).BIBLIOGRAPHY
