In the Sermon on the Mount Jesus said that we should take care of the widow, the orphan, the lame, etc.
Some interpret that to mean that those who choose to follow Jesus should do that.
Some interpret it to mean that the government should force everyone to obey Jesus ... in this instance...but not in other situations of the teachings of Jesus.
Taxes are not charitable giving. It is forced confiscation.
Government isnt charity and was never established to be.
