Tithing, the act of giving ten percent of your income to the church, is not required in the New Testament. Any minister who teaches you to the contrary is misleading you. The proof is right there in the New Testament book of Acts.
The book of Acts tells about what the apostles of Jesus did shortly after the resurrection. It describes the new way God expected them to live in. When we read the 15th chapter of the book, their commands become very clear.
     Now, tithing is a law of the Old Testament. Plain and simple, it was taught in the Law of Moses that the Jews had to pay three different tithes. One tithe they had to pay to the priests so that the ministry would be supported. A second tithe had to be saved up for the sole purpose of financing the seven festivals that the Jews had to observe every year. The third tithe was to be paid to their priests the third and sixth year of a sever year cycle to pay for the support of the poor and needy in the land. This was the law of tithing in the Old Testament. This was the only law that the Jews knew. This is what they were talking about.
     In the book of Acts, chapter 15, the question comes up, “Should the new non-Jewish converts be required to obey the Law of Moses and be circumcised before they can be Christian?” This was a logical question to some who had converted to Christianity but were former members of a strict sect of the old Jewish religion. The apostles deliberated and made a very prominent decision. The answer was a resounding “NO!” Let me show you exactly what they said.
 Ac:15:1: And certain men which came down from Judaea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved.
Ac:15:2: When therefore Paul and Barnabas had no small dissension and disputation with them, they determined that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question.
Ac:15:5: But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses.
And the apostles and elders came together for to consider of this matter.
Ac:15:7: And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.
Ac:15:8: And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;
Ac:15:9: And put no difference between us and them, purifying their hearts by faith.
Ac:15:10: Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?
Ac:15:11: But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.
Ac:15:13: And after they had held their peace, James answered, saying, Men and brethren, hearken unto me:
Ac:15:19: Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God:
Ac:15:20: But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.
There you have it, folks. The entire Old Testament was repealed. No law pertaining to it, including tithing, had to be obeyed. Now. How strongly did the Apostles feel about making sure that this message was delivered to the Gentiles? See below.
Ac:15:22: Then pleased it the apostles and elders, with the whole church, to send chosen men of their own company to Antioch with Paul and Barnabas; namely, Judas surnamed Barsabas, and Silas, chief men among the brethren:
Ac:15:23: And they wrote letters by them after this manner; The apostles and elders and brethren send greeting unto the brethren which are of the Gentiles in Antioch and Syria and Cilicia:
Ac:15:24: Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment:
Ac:15:25: It seemed good unto us, being assembled with one accord, to send chosen men unto you with our beloved Barnabas and Paul,
Ac:15:26: Men that have hazarded their lives for the name of our Lord Jesus Christ.
Ac:15:27: We have sent therefore Judas and Silas, who shall also tell you the same things by mouth.
Ac:15:28: For it seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things;
Ac:15:29: That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.
Ac:15:30: So when they were dismissed, they came to Antioch: and when they had gathered the multitude together, they delivered the epistle:
Ac:15:31: Which when they had read, they rejoiced for the consolation.
     So you see, the people were told, very emphatically and with great purpose, that they don’t have to keep any of the Old Testament Laws but they recommended that they “abstain from meats offered to idols, and from blood, and from things strangled and from fornication.” These four things were the only things necessary, from the entire Old Testament, that were required of them. Period. Case closed!
So why do the ministers today require tithing? Greed. Why else? It is convenient for them to require money from you and to claim that it is God’s will, even after the Apostles said it wasn’t. Read again the verse above: Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment:
     You see? Those who were telling the new disciples that they should be keeping the law were “troubling” them, “subverting” them. The Apostles gave “no such commandment.”
What a condemnation to those who would have you pay them ten percent of your income!
What else does the Bible say about the Old Testament?

2Co:3:6: (God) Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.
2Co:3:7: But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
2Co:3:8: How shall not the ministration of the spirit be rather glorious?
2Co:3:9: For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.
2Co:3:10: For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
2Co:3:11: For if that which is done away was glorious, much more that which remaineth is glorious.
The Ten Commandments were the only part of the law written in stone.
Exodus:34:28: And he (Moses) was there with the LORD forty days and forty nights; he did neither eat bread, nor drink water. And he wrote upon the tables the words of the covenant, the ten commandments.
     The Old Covenant WAS the 10 commandments. But it was replaced by a better covenant. Read again: 2Co:3:11: For if that which is done away was glorious, much more that which remaineth is glorious.
     The Old Testament was replaced by the New Testament. Even the 10 commandments, which defined the Old Testament, was replaced by the new teachings of Jesus. So it was completely and totally replaced by Jesus. No part of the Old Covenant was binding.
     Now the New Testament was binding and required another kind of righteousness based upon faith, not the obedience to the Law of Moses. Faithful Christians have their own responsibilities (which I will not elaborate on here.) But the fact is, none of the Old Testament is binding, not tithing especially.
So the requirement that you must tithe is their lie. It is their sin for they subvert your souls. So say the apostles of Jesus Christ.
