[daniel1212]

The disciples never met on sunday, except to collect an offering, which was forbidden on the sabbath.

That is simply not true, as in fact, nowhere is a NT church shown specifically meeting on the 7th day, nor is the 4th command ever reiterated with the other 9 are, while many times the disciples are shown meeting on the 1st day - incldg. with the Lord. See post 26

Acts 17:2 Then Paul, as his custom was, went in to them,and for three Sabbaths reasoned with them from the Scriptures.

[editor-surveyor]

There are two times where scripture says that they “came together” on the first day, and both of those times were at the end of the sabbath, in the evening, for Havdalah. One of those two times, it was really “the first of the weeks,” meaning the beginning of the weeks of pentecost.

Paul did tell his followers to come together on the first day of the week, but it was regarding money for Jerusalem.
