How do we know tithing is not required for Christians?

The New Testament does not affirm the practice of tithing for Christians, which further aligns with the theological understanding that believers are under grace rather than law. The only reference often cited is Matthew 23:23, where Jesus rebukes the Pharisees for their legalistic adherence to tithing while neglecting justice, mercy, and faith. While the scribes and Pharisees were warranted to tithe because they were under the Old Covenant, non-Jews, including Gentile believers in Christ, do not share this covenant obligation. The New Testament emphasizes giving based on grace (2 Corinthians 8:1-2), not legal compulsion, and encourages Christians to support the ministry freely rather than out of a sense of duty or fear of divine retribution.
