Are you saying that Jesus taught that it is our duty to pay taxes?
What's your take on his words, "sell all your possessions and give the money to the poor?"
Your tax money pays for abortions, you think Jesus accepts that, because of an image on a coin?
Read your Bible. They were trying to trick Jesus by having him say do not pay taxes. Instead, he asked them whose image is on the coin. Caesar, they answered. He then said pay unto Caesar what is Caesars - the coins - but pay unto God what is Gods.
There are also many instances in the New Testament where it states to obey your supieriors.
