17 Tell us therefore, what thinkest thou? Is it lawful to give tribute unto Caesar, or not?” 18 But Jesus perceived their wickedness and said, “Why tempt ye Me, ye hypocrites? 19 Show Me the tribute money.” And they brought unto Him a penny. 20 And He said unto them, “Whose is this image and superscription?” 21 And they said unto Him, “Caesar’s.” Then said He unto them, “Render therefore unto Caesar the things which are Caesar’s, and unto God the things that are God’s.” - Matthew 22:17-21 KJ21
Clearly, Jesus knows of Caesar. Does Caesar know of Jesus? If not, after all the heavenly things Jesus did in Judea, how come they've never spread to Rome?
