6. Christianity – Founded by Jesus and his disciples, especially the apostle Paul (c. 30-68 A.D.), who taught that God’s love & POS includes everyone and that the NT superseded the OT. However, knowledge of the NT was limited by hand-copying, so most church leaders deferred to the bishop in Rome regarding doctrine and biblical Christianity morphed into Roman Catholicism after Constantine made it legal and authorized the Nicene Council/Creed (in 325). Even as areas in Europe became Christendom nominally, the majority of humanity remained ignorant of GW and dependent on GR for knowledge of God, so there was a Dark Age as Germanic migrations ended the Roman Empire (in 476) and Buddhism spread eastward to Japan.
7. Islam - Founded by Mohammed in 622 in Medina, where he dictated the Qu'ran teaching that only one God (Allah) exists. Although Surahs such as 2:62, 2:87 & 2:136 claim to affirm the teachings of Moses and Jesus as prophets, no mention is made of Messiah's gospel or of Paul's epistles. In 634 caliph Omar I began a campaign of Muslim conquest across North Africa to Spain and eastward to India by 715. In Persia Islam suppressed Zoroastrianism, which taught that humans should exercise volition to participate with the god Ahura Mazda in a cosmic struggle against chaos and falsehood. Meanwhile Christendom “fiddled” with whether Christ Jesus had one (human) or two (also divine) wills, and Charles Martel began the Holy Roman Empire (HRE) in Europe (in 732).
8. Medievalism - The Germanic tribes that migrated into Europe formed various kingdoms protected by lords living in castles, where in 771 Charlemagne inherited the Frankish kingdom, annexed Saxony, Lombardy and Bavaria and was crowned HRE in 800, when Pope Leo III separated RC from the Byzantine Empire (BE). In 826, the king of Denmark converted to RC, opening the door for its spread to Scandinavia. In 843 the Treaty of Verdun divided the Frankish Empire into French, German and Italian dynasties. Meanwhile, Muslims sacked Rome in 846 as Vikings or Norsemen attacked Britain, Ireland and Germany, then took Kiev in 850, discovered Iceland in 861 attacked Constantinople via the Black Sea in 865, 904 and 941 and discovered Greenland. In 907 the Magyars in Hungary defeated the Moravians and raided Germany and Italy. In 951, Otto I of Germany became king of the Franks and Lombards and was crowned HRE in 962. The Poles converted to RC in 966. Eastern Catholicism was accepted by Kiev (Russia) in 988. By 1000 RC had reached Greenland, and Judaism was strongest in Spain. The Danes deposed the English king in 1013, and they conquered Norway in 1028. The Caliphate in Cordoba was abolished in 1031, and the Seljuk Turks gained strength in Turkestan in 1042. In 1054, the schism between RC and what became Eastern Orthodoxy (EO), due mainly to its rejection of the primacy of the Pope, became permanent (“Great”).
9. Crusades - Numerous political events influenced the HOB in Europe: The Danes in England were defeated by William of Normandy in 1066, Poland took Kiev in 1067, the Normans conquered Italy in 1071, the Seljuks conquered Armenia in 1064 and Syria-Palestine in 1075, and El Cid took Valencia from the Muslim Moors in 1094. In 1095 Pope Urban II proclaimed the First Crusade, which took Jerusalem from the Seljuks in 1099, in 1113 the order of Knights Hospitallers was organized in order to protect a hospital for pilgrims, in 1182 Jews were banished from France and in 1185 the order of Knights Templars was formed for the purpose of protecting pilgrims on the route from Jaffa to the Temple Mount. In 1204, the Fourth Crusade captured Constantinople, and in 1209 Pope Innocent III authorized the Albigensian Crusade against the Cathar heresy in France, which effectively began the period of the Inquisition (that continued with the prohibition of Bible reading in Toulouse in 1229).
During this era, RC was influenced by the ideas of various philosophers: 1. Anselm of Canterbury's tracts (c. 1060) reconciled divine foreknowledge with human free will and argued logically for the existence of God as the first cause and greatest conceivable being; 2. Berenger of Tours opposed the RC doctrine of transubstantiation for being irrational; 3. Peter Abelard was condemned by a council (in 1141) for utilizing the dialectical method of stating pros and cons; 4. about 1175 Peter Waldo began preaching poverty as the way to perfection, founding a movement that presaged the reform of Luther, 5. in Spain Avicebron published the neo-Platonist idea that God can be apprehended only by intuition or mystical experience rather than by reason, and 6. Moses Maimonides attempted to align Jewish theology with Aristotelianism, saying that if statements in the OT contradict reason, then they should be interpreted allegorically, and identifying God as first Mover and necessary Being.
