Q: Objection 1: It would seem that men are not bound by precept to pay tithes. The commandment to pay tithes is contained in the Old Law (Lev. 27:30), "All tithes of the land, whether of corn or of the fruits of trees, are the Lord's," and further on (Lev. 27:32): "Of all the tithes of oxen and sheep and goats, that pass under the shepherd's rod, every tenth that cometh shall be sanctified to the Lord." This cannot be reckoned among the moral precepts, because natural reason does not dictate that one ought to give a tenth part, rather than a ninth or eleventh. Therefore it is either a judicial or a ceremonial precept. Now, as stated above (I-II, Q. 103, A. 3; Q. 104, A. 3), during the time of grace men are hound neither to the ceremonial nor to the judicial precepts of the Old Law. Therefore men are not bound now to pay tithes.

Obj. 2: Further, during the time of grace men are bound only to those things which were commanded by Christ through the Apostles, according to Matt. 28:20, "Teaching them to observe all things whatsoever I have commanded you"; and Paul says (Acts 20:27): "I have not spared to declare unto you all the counsel of God." Now neither in the teaching of Christ nor in that of the apostles is there any mention of the paying of tithes: for the saying of our Lord about tithes (Matt. 23:23), "These things you ought to have done" seems to refer to the past time of legal observance: thus Hilary says (Super Matth. can. xxiv): "The tithing of herbs, which was useful in foreshadowing the future, was not to be omitted." Therefore during the time of grace men are not bound to pay tithes.

Obj. 3: Further, during the time of grace, men are not more bound to the legal observances than before the Law. But before the Law tithes were given, by reason not of a precept but of a vow. For we read (Gen. 28:20, 22) that Jacob "made a vow" saying: "If God shall be with me, and shall keep me in the way by which I walk . . . of all the things that Thou shalt give to me, I will offer tithes to Thee." Neither, therefore, during the time of grace are men bound to pay tithes.

Obj. 4: Further, in the Old Law men were bound to pay three kinds of tithe. For it is written (Num. 18:23, 24): "The sons of Levi . . . shall . . . be content with the oblation of tithes, which I have separated for their uses and necessities." Again, there were other tithes of which we read (Deut. 14:22, 23): "Every year thou shalt set aside the tithes of all thy fruits, that the earth bringeth forth year by year; and thou shalt eat before the Lord thy God in the place which He shall choose." And there were yet other tithes, of which it is written (Deut. 14:28): "The third year thou shalt separate another tithe of all things that grow to thee at that time, and shalt lay it up within thy gates. And the Levite that hath no other part nor possession with thee, and the stranger, and the fatherless, and the widow, that are within thy gates, shall . . . eat and be filled." Now during the time of grace men are not bound to pay the second and third tithes. Neither therefore are they bound to pay the first.

Obj. 5: Further, a debt that is due without any time being fixed for its payment, must be paid at once under pain of sin. Accordingly if during the time of grace men are bound, under necessity of precept, to pay tithes in those countries where tithes are not paid, they would all be in a state of mortal sin, and so would also be the ministers of the Church for dissembling. But this seems unreasonable. Therefore during the time of grace men are not bound under necessity of precept to pay tithes.
