Ans. 1. That is supplied; for that by this very text this day is appointed, above all the days of the week, to do this holy duty in.
2.. You must understand that this order is but additional, and now enjoined to fill up that which was begun as to holy exercise of religious worship by the churches long before.
3. The universality of the duty being enjoined to this day, supposes that this day was universally kept by the churches as holy already.
4. And let him that scrupleth this, shew me, if he can, that God by the mouth of his apostles did ever command that all the churches should be confined to this or that duty on such a day, and yet put no sanction upon that day; or that he has commanded that this work should be done on the first day of the week, and yet has reserved other church ordinances as a public solemnization of worship to him, to be done of another day, as of a day more fit, more holy.
5. If charity, if a general collection for the saints in the churches is commanded on this day, and on no other day but this day; for church collection is commanded on no other, there must be a reason for it: and if that reason had not respect to the sanction of the day, I known to why the duty should be so strictly confined to it.
6. But for the apostle now to give with this a particular command to the churches to sanctify that day as holy unto the Lord, had been utterly superfluous; for that they already, and that by the countenance of their Lord, and his church at Jerusalem, had done.
Before now, I say, it was become a custom, as by what hath been said already is manifest: wherefore what need that their so solemn a practice be imposed again upon the brethren? An intimation now of a continued respect thereto, by the very naming of the day, is enough to keep the sanctity thereof on foot in the churches. How much more then, when the Lord is still adding holy duty to holy duty, to be performed upon that day. So then, in that the apostle writes to the churches to do this holy duty on the first day of the week, he puts them in mind of the sanction of the day, and insinuates, that he would still have them have a due respect thereto.
Quest. But is there yet another reason why this holy duty should, in special as it is, be commanded to be performed on the first day of the week?
Ans. 1. Yes: for that now the churches were come together in their respective places, the better to agree about collections, and to gather them. You know church worship is a duty, so long as we are in the world, and so long also is this of making collections for the saints. And for as much as the apostle speaks here, as I have hinted afore, of a church collection, when is it more fit to be done, than when the church is come together upon the first day of the week to worship God?
2. This part of worship is most comely to be done upon the first day of the week, and that at the close of that day's work. For thereby the church shows, not only her thankfulness to God for a sabbath day's mercy, but also returneth him, by giving to the poor, that sacrifice for their benefit that is most behoveful to make manifest their professed subjection to Christ (Prov 19:17; 2 Cor 9:12-15). It is therefore necessary, that this work be done on the first day of the week, for a comely close of the worship that we perform to the Lord our God on that day.
