Jimmy, do those verses in Acts mean worship?
The book of Acts recounts the development of doctrine and practice in the early Church. Yet the first day of the week is mentioned only once, in Acts 20:7-12. “Now on the first day of the week, when the disciples came together to break bread *, Paul, ready to depart the next day, spoke to them and continued his message until midnight” (v. 7). This was a one-time farewell meeting and meal, not a regular worship service. And when we understand that by biblical reckoning days are from sunset to sunset, we can see that the before-midnight portion of “the first day” is actually on Saturday. This “first day” gathering was a Saturday evening event! And at sunrise Sunday morning, Paul began the hard work of a 20-mile hike (vv. 11-14)—not what one would expect if he considered Sunday his Sabbath day of rest! *
None of what you said is in the verses. It does not say it is a one time thing, that is your own interjection and is not in the text.
Acts 13:14: “But when they departed from Perga, they came to Antioch in Pisidia, and went into the synagogue on the Sabbath day and sat down.”
“But,” some might argue, "Paul was just meeting with the Jews on Saturday since that was *their *
Sabbath!" However, the book of Acts tells us that “when the Jews went out of the synagogue, the Gentiles begged that these words might be preached to them the
next Sabbath” (13:42). Here was Paul’s grand opportunity to inform the Gentiles that they would now meet on Sunday! But did he? On the contrary!
“The next Sabbath almost the whole city came together to hear the word of God” (v. 44).
The truth of the matter is that neither Paul nor ANY of the Apostles uttered
one single word about changing God’s holy Sabbath or any part of the Ten Commandments. Rather, as they had been taught by Christ Himself, they kept, and always assembled on, the seventh day.
What about when Paul traveled through predominately Gentile areas? God’s Word tells us, “Now when they had passed through Amphipolis and Apollonia, they came to Thessalonica, where there was a synagogue of the Jews. Then Paul,
as his CUSTOM was, went in to them, and
for three Sabbaths reasoned with them from the Scriptures” (17:1-2).
It was clearly Paul’s “custom” to meet on the Sabbath. Acts 18:4 tells us that
"he reasoned in the synagogue every Sabbath, and persuaded both Jews and Greeks."
They preached on the sabbath. On the lords day they celebrated the ressurection. The first day was when they broke bread and blessed the bread and ate.
