For all their “christianity”, republicans in the US are pretty hypocritical.
Jesus actually teached that everybody deserves to get fed and housed. That everybody deserves healthcare. That people should care for other people in their community. That is essentially the core principles of socialism.
I would argue that the verse where he said I am here to fulfill the old testament is more proving that christians should follow the old testament. There is not much in bible canon to suggest the old testament was vetod by Jesus, I would say there’s more than enough evidence in bible canon that old testament rules still apply to all christians.
Almost everything Jesus taught was in contradiction to the ot.
“Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill”
