Really? Show me anywhere in the NT where a Christian has a obligation to tithe?
I think that a lot of people have missed that tithing was to support the tribe of Levi who were the priests and had no land. That doesn’t hold true for the Christian church.
"But a man named Ananias with his wife Sapphira sold a piece of property, and with his wife's knowledge he kept back some of the proceeds, and brought only a part and laid it at the apostles' feet." "But Peter said, "Ananias, why has Satan filled your heart to lie to the Holy Spirit and to keep back part of the proceeds of the land? While it remained unsold, did it not remain your own? And after it was sold, was it not at your disposal? How is it that you have contrived this deed in your heart? You have not lied to men but to God."
