This ceremony was about the sheaf that was to be waved, and bread of first fruits, which was a type of Christ; for he is unto God 'the first fruits of them that slept' (1 Cor 15:20).

This sheaf, or bread, must not be waved on the old seventh day, but on the morrow after, which is the first day of the week, the day in which Christ rose from the dead, and waved himself as the first fruits of the elect unto God. Now from this day they were to count seven sabbaths complete, and on the morrow after the seventh sabbath, which was the first day of the week again; and this Pentecost upon which we now are, then they were to have a new meat offering, with meat offerings and drink offerings, &c.

And on the selfsame day they were to proclaim that that first day should be a holy convocation unto them. The which the apostles did, and grounded that their proclamation so on the resurrection of Jesus Christ, not on ceremonies, that at the same day they brought three thousand souls to God (Acts 2:41).

Now what another signal [applause] was here put upon the first day of the week! The day in which our Lord rose from the dead, assembled with his disciples, poured out so abundantly of the Spirit, and gathered even by the first draught that his fishermen made by the gospel, such a number of souls to God.

Thus then they proclaimed, and thus they gathered sinners on the first first-day that they preached; for though they had assembled together over and over with their Lord before therein, yet they began not jointly to preach until this first day Pentecost.

Now, after this the apostles to the churches did never make mention of a seventh day sabbath. For as the wave sheaf and the bread of first fruits were a figure of the Lord Jesus, and the waving, of his life from the dead: so that morrow after the sabbath on which the Jews waved their sheaf, was a figure of that on which our Lord did rise; consequently, when their morrow after the sabbath ceased, our morrow after that began, and so has continued a blessed morrow after their sabbath, as a holy sabbath to Christians from that time ever since.

Fourth, We come yet more close to the custom of churches; I mean, to the custom of the churches of the Gentiles; for as yet we have spoken but of the practice of the church of God which was at Jerusalem; only we will add, that the customs that were laudable and binding with the church at Jerusalem, were with reverence to be imitated by the churches of the Gentiles; for there was but one law of Christ for them both to worship by.

Now then, to come to the point, to wit, that it was the custom of the churches of the Gentiles, on the first day of the week, but upon no other that we read of,[18] to come together to perform divine worship to their Lord.

Hence it is said 'And upon the first day of the week, when the disciples came together to break bread,' &c. (Acts 20:7). This is a text, that as to matter of fact cannot be contradicted by any, for the text saith plainly they did so, the disciples then came together to break bread, the disciples among the Gentiles, did so.

Thus you see that the solemnizing of a first day to holy uses was not limited to, though first preached by the church that was at Jerusalem. The church at Jerusalem was the mother church, and not that at Rome, as some falsely imagine; for from this church went out the law and the holy word of God to the Gentiles. Wherefore it must be supposed that this meeting of the Gentiles on the first day of the week to break bread, came to them by holy tradition[19] from the church at Jerusalem, since they were the first that kept the first day as holy unto the Lord their God.
