How about if it is pointed out that many of Jesus' Followers/Disciples left Him at various times.I can see that.
So you believe that the followers of Jesus Christ who were there in the city during that time, were not Christians?
Even if they all were not there in the city during that event, whereby He came riding in on a donkey, the question still remains.
Do you believe followers of Jesus Christ were Christains?
What is a follower of Jesus Christ if not a Christian?
A prime example would be seem n John 6:51-58 after they heard His statements about Him being the Bread of Life, and that true Believers must eat His body and drink His blood. After that, many of His Followers "left Him." It turns out, they were not Christians.
In fact, John 8 has Jesus saying to some who "believed in Him," "Now you seek to kill me." He called their Father "the Devil."
Do you still think all who follow and believe in Jesus are thereby Christians? Yes? No?
