A lot of posts on this thread indicate that positions are being taken based on false teaching rather than the scriptures.
There is no such thing as Christian tithing. That is not scriptural. Tithing ended at the cross per Hebrews 7:5,12,18.
I believe you are taking Hebrews 7 out of context. The writer of Hebrews was talking about the Levitical priesthood not being perfect, and that a change was needed after the order of Melchizek, under which Jesus was born. Hebrews was justifying why the Levitical priests tithed, because there was a greater order above them, and that even Abraham tithed Melchizedek. I don't think we're greater than Jesus are we?
The New Testament calls for a higher standard. We are to pray and seek the Spirit. Being Spirit led instead of using out-dated Old Testament standards that ended at the cross, I find myself giving between 30% and 50% of my income on a consistent basis.
As far as I'm concerned, tithes and offerings (which are above and beyond the tithe) always existed. Offerings are of one's own free will.
1 Peter 2:5 (KJV) “Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.”
1 Peter 2:9 (KJV) “But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should show forth the praises of him who hath called you out of darkness into his marvellous light:”
1 - According to the scriptures, priests do not tithe (Numbers 18).
Numbers 18:26 requires the Levites to tithe on the tithes received of the people referred to as the heave offering. Hebrews 7 also says that even Abraham tithed Melchizedek. The Levites came under Abraham.
Hebrews 7:[1] For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;
[2] To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace;
[3] Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.
[4] Now consider how great this man was, unto whom even the patriarch Abraham gave the tenth of the spoils.
[5] And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:
[6] But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.
[7] And without all contradiction the less is blessed of the better.
[8] And here men that die receive tithes; but there he receiveth them, of whom it is witnessed that he liveth.
[9] And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham.
[10] For he was yet in the loins of his father, when Melchisedec met him.
2 - As priests, all born-again believers are equal. There is no better or lesser among us. God has not designated any born-again believers to collect His tithe.
In the Book of Acts, the believers gave all and all things became common. Things were divided among the people according to their need.
It's not about who's better than the other. It's about supporting the work of God. Though we ought to submit to one another in the humility of God, there are still ranks and authorities to follow. Even the angels have ranks, wherefore Michael is called the Arch Angel, and Jesus is called the Captain of the Lord's Hosts. I never knew an army that could function without rank and order.
1Corin.9:3 [4] Have we not power to eat and to drink?...[6] ... have not we power to forbear working?...[8] Say I these things as a man? or saith not the law the same also?[9] For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen?[10] Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope.[11] If we have sown unto you spiritual things, is it a great thing if we shall reap your carnal things?...
[13] Do ye not know that they which minister about holy things live of the things of the temple? and they which wait at the alter are partakers with the alter?[14] Even so hath the Lord ordained that they which preach the gospel should live of the gospel.
Jesus didn't come to do away with the Law. He came to fulfill it. (Matt 5:17)
3 - To try and “tithe” today is denying that you are a part of a Royal Priesthood.
I defer to 1Corin.9. I don't think Abraham thought any less of himself as God's servant. Jesus also praised the poor woman who tithed 2 mites in Luke 21:4.
Are you an Old Testament Jew or a New Testament born-again believer?
