When read as a whole in context the Christian Bible does not support the social gospel
If the social gospel means taxing people to give to the poor
Although both the old and new testament support voluntary charity to give to the poor and there even is an old testament tithe
Using violence, theft, kidnapping or fraud to force people to tithe or give to the poor against their will and calling it taxation violates the old and new testament
Paying taxes is not a sin
Enforcing taxes is a sin
