The greatest of all Protestant Reformers, was Rev. Prof. Dr. John Calvin (1509-64). He lived and testified and died — during the time of Islam’s greatest expansion into Eastern Europe.
Islam was formulated by Mohammed and his successors from the seventh century onward. It is a fusion of: portions of the Old Testament; fragments from the Apocrypha; scraps from the New Testament; parts of Post-Christian pseudepigraphical books generally authored by later sectarians; Arabic culture; the personal utterances of Mohammed as inscripturated especially by his favourite wife Khadiya; and traditions later attributed to him and to his close successors.
