The name of the savior yahshua was the orignal name in the bible did the roman catholic take out the true name of yahshua and replace the true name with the name justus christus from a idol of the mother and child that they saw in india?

the name jesus is the orgin of this name from pagan worship and why did the translators take out the hebrew names of the father and son and replace them with names that were not in the bible in the first place?
