This is apparent in that the tenths alone were not thought enough even in the time of the law, to give towards the public worship of God: for besides the tenths, there were the first-fruits, and oblations, and many sorts of sacrifices; and yet at the same time, the poor were to be maintained by liberal gifts besides the tenths: and though we read not of much given to the maintenance of their rulers and magistrates, before they chose to have a king, yet afterwards we read of much; and before, the charges of wars and public works lay upon all.
In most places with us, the public ministry is maintained by glebe and tithes, which are none of the people's gifts at all, for he that sold or leased them their lands, did suppose that tithes were to be paid out of it, and therefore they paid a tenth part less for it, in purchase, fines, or rents, than otherwise they should have done; so that I reckon, that most of them give little or nothing to the minister at all. Therefore they may the better give so much the more to the needy, and to other charitable uses. But where minister, and poor, and all are maintained by the people's contribution, there the tenths are too little for the whole work; but yet to most, or very many, the tenths to the poor alone, besides the maintenance of the ministry and state, may possibly be more than they are able to give. The tenths even among the heathens, were given in many places to their sacrifices, priests, and to religious, public, civil works, besides all their private charity to the poor.
I find in Diog. Laertius, lib. i. (mihi) 32. that Pisistratus the Athenian tyrant, proving to Solon (in his epistle to him) that he had nothing against God or man to blame him for, but for taking the crown; telling him, that he caused them to keep the same laws which Solon gave them, and that better than the popular government could have done, doth instance thus: _Atheniensium singuli decimas frugum suarum separant, non in usus nostros consumendas, verum sacrificiis publicis, commodisque communibus, et si quando bellum contra nos ingruerit, in sumptus deputandas_: that is, Every one of the Athenians do separate the tithes of their fruits, not to be consumed to our uses, but to defray the charge in public sacrifices, and in the common profits, and if war at any time invade us. And Plautus saith, _Ut decimam solveret Herculi_. Indeed as among the heathens the tithes were conjunctly given for religious and civil uses, so it seems that at first the christian emperors settled them on the bishops for the use of the poor, as well as for the ministers, and church service, and utensils. For to all these they were to be divided, and the bishop was as the guardian of the poor: and the glebe or farms that were given to the church, were all employed to the same uses; and the canons required that the tithes should be thus disposed of by the clergy; _non tanquam propriæ, sed domino oblatæ_: and the emperor Justinian commanded the bishops, _Ne ea quæ ecclesiis relicta sunt sibi adscribant sed in necessarios ecclesiæ usus impendant_; lib. xliii. cap. de Episc. et Cler. vid. Albert. Ranzt. Metrop. lib. i. cap. 2. et sax. lib. vi. cap. 52. And Hierom (ad Damasc.) saith, _Quoniam quicquid habent clerici pauperum est; et domus illorum omnibus debent esse communes; susceptioni peregrinarum et hospitum invigilare debent; maxime curandum est illis, ut de decimis et oblationibus, cœnobiis et Xenodochiis qualem voluerint et potuerint sustentationem impendant_.
