Taxes:
Matthew 22:21 They say unto him, Caesar's. Then saith he unto them, Render therefore unto Caesar the things which are Caesar's; and unto God the things that are God's
And welfare:
Matthew 5:38-42 You have heard that it was said, 'An eye for an eye, and a tooth for a tooth.' But I tell you, do not resist an evil person. If someone strikes you on the right cheek, turn to him the other also. And if someone wants to sue you and take your tunic, let him have your cloak as well. If someone forces you to go one mile, go with him two miles. Give to the one who asks you, and do not turn away from the one who wants to borrow from you
And more welfare/communism
Matthew 14:16-20 But Jesus said unto them, They need not depart; give ye them to eat. 17And they say unto him, We have here but five loaves, and two fishes. 18He said, Bring them hither to me. 19And he commanded the multitude to sit down on the grass, and took the five loaves, and the two fishes, and looking up to heaven, he blessed, and brake, and gave the loaves to his disciples, and the disciples to the multitude. 20And they did all eat, and were filled: and they took up of the fragments that remained twelve baskets full.
And universal healthcare
Matthew 10:8 Heal the sick, raise the dead, cleanse those who have leprosy, drive out demons. Freely you have received, freely give.
