The missing event that coincides with the year 36 CE in the timeline you provided is Paul the apostle has vision of Jesus.
Explanation:
-
The conversion of Paul (formerly Saul) is traditionally dated to around 36 CE, which is when he had his vision of Jesus on the road to Damascus. This event is significant because Paul became one of the most influential figures in the spread of Christianity, establishing many of the early Christian communities and writing several letters that are part of the New Testament.
-
The other options, such as Constantine's conversion, the Council of Nicaea, and the Edict of Milan, all occurred in the 4th century CE, much later than 36 CE.
