Acts 2:42

And they continued stedfastly in the apostles teaching and fellowship, in the breaking of bread and the prayers.

The apostles' teaching ... As this church did, so should every church do, the apostles' teaching being the only doctrinal authority in the Christian religion. This is limited, of course, to the teachings of the New Testament.

And fellowship ... Campbell rendered this "contribution," stating that:

The contribution of money for the wants of the brotherhood, appears to be its import in this passage as in Romans 15:16.[46]

In the breaking of bread ... Barnes thought that it was impossible to tell whether this has reference to "taking ordinary food, feasts of charity, or the Lord's Supper";[47] but Milligan, Boles and Campbell were certain that the reference is to the Lord's Supper.

Campbell supported his conclusion thus:

The expression itself may designate an ordinary meal, as in Luke 24:35; but that here would be an unmeaning notice. There can be no doubt that the Eucharist at this period was preceded uniformly by a common repast, as when the ordinance was instituted. Most scholars hold that this was the prevailing usage in the first centuries after Christ; and we have traces of this practice in 1 Corinthians 11:20ff, and in all probability in Acts 2:46.[48]

The bread only being mentioned in this passage is held by the Roman Catholic Church to support their custom of distributing only the bread to their congregations, calling it "communion under one kind." However, as the scholarly Hackett said: (this mention of the bread alone) "is obviously a case in which the leading act of a transaction gives name to the transaction itself."[49] The figure of speech thus used is synecdoche, and the Protestant world have little complaint against Catholics for missing the synecdoche here in view of the fact that they themselves have missed it so spectacularly in reading salvation by faith as salvation by "faith alone." The errors are one and the same.

And the prayers ... Whereas in Judaism, prayers were offered at stated times of the day, the Christians offered prayers at any and all times, and in any and all places.
