Whether men are bound to pay first-fruits?

Objections

Objection 1 : It would seem that men are not bound to pay first-fruits. After giving the law of the first-born the text continues (Ex. 13:9): "It shall be as a sign in thy hand," so that, apparently, it is a ceremonial precept. But ceremonial precepts are not to be observed in the New Law. Neither therefore ought first-fruits to be paid.
Objection 2 : Further, first-fruits were offered to the Lord for a special favor conferred on that people, wherefore it is written (Dt. 26:2,3): "Thou shalt take the first of all thy fruits . . . and thou shalt go to the priest that shall be in those days, and say to him: I profess this day before the Lord thy God, that I am come into the land, for which He swore to our fathers, that He would give it us." Therefore other nations are not bound to pay first-fruits.
Objection 3 : That which one is bound to do should be something definite. But neither in the New Law nor in the Old do we find mention of a definite amount of first-fruits. Therefore one is not bound of necessity to pay them.
