New Testament mentions nothing on Christians having to pay tithes. Jesus and His disciples never paid tithes neither did they instruct anyone to do so. Paul wrote three quarters of the New Testament and had many opportunities to talk about tithes but he never did!

What did Jesus say about tithes and offerings?

Jesus says, “Woe to you, teachers of the law and Pharisees, you hypocrites! You give a tenth of your spices–mint, dill and cumin. But you have neglected the more important matters of the law-justice, mercy and faithfulness. You should have practiced the latter, without neglecting the former.”

Who collected tithes in the Bible?
