Well I would dispute that understanding of history because the New Testament in Acts indicates they were meeting on Sunday. That said, while my preferred day is Sunday, I know it doesn’t matter. Arguments over the day miss the whole point. For the Christian, our true sabbath rest is found in Christ.
Really what you are saying is that it doesn't matter to you. God should have a say in it, don't you think?
If you were familiar with the To this day, the Chosen People I pray that this brings a lamp to you walk. If you were to read Acts carefully,
shalom b'SHEM Yah'shua HaMashiach
it does not say Sunday,
but instead it says the first day.
customs of Yah'shua it would become clear.
celebrate the end of Shabbat
with a meal called an Oneg on the
beginning of the First Day,
which occurs at evening on the
day we call Saturday.
