Most Christian faiths believe that a 10% tithe is Biblical and appropriate. Of course, one can find a Bible version and interpret the Bible to suit one’s own agenda. I don’t care.
Don’t talk to us about the bible, lawyer, your LDS offshoot sect of mormonism threw FLDS/LDS “Prophet” Joseph Smith’s retranslation in the dumpster after Brigham Young declared it a fraud.
You won't find references to tithing in the New Testament (other than the note in Hebrews that Abraham paid tithes to Melchizedek, and thus the Levites, in the loins of Abraham, also paid this tithe). And the references in the Old Testament were unique to the Nation of the Hebrews for the maintenance of the Levite priesthood. A priesthood that has been forever abolished by our Great High Priest, the Lord Jesus Christ.
You'll not find references to tithing in the Confessions of the Reformation: the Belgic and Westminster Confessions. Martin Luther did not support tithing,so I presume this excludes the Lutherans.
The Roman Catholics and Eastern Orthodox churches don't tithe.
I believe many individual Baptist churches require tithing... But I'd hardly call that as representative of 'most' Christian faiths.
But that said, clearly all we have belongs to the Lord. We are told to be cheerful givers and to provide for those who provide us with spiritual food.
I don't see the tithing requirement, but knowing that we owe everything to the Lord, giving back ten percent of what He has given us for his service seems a bare minimum. But that is for the individual to decide.
