Was Jesus rich? No, not in a money way. Jesus said we are NOT to store up riches.
Look at the four Gospels and evaluate exactly what Jesus did. He was helping the sick, feeding the hungry, and getting his followers to redistribute their wealth, not storing up wealth.
Powerful religious leaders of his day vehemently opposed Jesus. When given the opportunity by the Roman Governor Pontius Pilot to free Jesus, the CHIEF PRIEST encouraged the angry mob to chose let a murderer go free over Jesus!
Jesus associated with gentiles and by doing so stirred up powerful, conservative religious leaders of his day in a bad way. Jesus recruited a hated tax collector to be one of his closest disciples, one of the 12 Apostles. Jesus felt it was the sick who needed a doctor to heal them.
When Jesus sent the twelve out to preach two by two, he told them to take nothing with them. They were to rely completely on God and on the hospitality of the people they met.
Just these few things sound liberal to me not conservative, using the language we are familiar with today.
"Do not store up for yourselves treasures on earth, where moth and rust consume and where thieves break in and steal; but store up for yourselves treasures in heaven, where neither moth nor rust consumes and where thieves do not break in and steal." Matthew 6:19-21
I think Jesus would find it difficult be a Republican or Democrat in America today.
