Tithing. How is Malachi 3:8-10 misused by churches.

What is the differences between “tithe” and “tithes”. Is this for the Body of Christ or Israel? How are verses in Malachi misused. Teaching tithing places us back under the law. Are we under grace or law in this dispensation-we are under grace. Giving should be done joyfully, cheerfully not under condemnations nor guilt.
