I'd like to add that orthodox Christianity must be traced back to the early church.
Sabbath worship cannot.
The Didache,,,,teachings on how to practice the Christian religion - written about 90AD by new studies (it had been believed to be written up to about 120AD) states that THE LORD'S DAY was for worshipping.
The Lord's Day is used two ways in the NT:
To describe when the Lord returns...THE DAY OF THE LORD
Sunday...the resurrection....THE LORD'S DAY
Acts 20:7
7On the first day of the week, when we were gathered together to break bread, Paul talked with them, intending to depart on the next day, and he prolonged his speech until midnight.
The first day of the week, at the time, was Sunday.

I address the history of the sabbath and the early church here (pages 186-361) -

I have read the real history. You should too (not attempting to be harsh, just an invitation to do the same).
I address the so called 'didache' in my book. Did you read it? (Pro, 18:13,17 KJB), If not, why not? It doesn't say what you think it does. Do you need me to copy my material and post it here? I will. See page 159 -

"What about ‘the Didache’?
“...
[Greek] (14) 1. Κατὰ κυριακὴν δὲ κυρίου συναχθέντες κλάσατε ἄρτον καὶ εὐχαριστήσατε, προεξομολογησάμενοι τὰ παραπτώματα ὑμῶν, ὅπως καθαρὰ ἡ θυσία ὑμῶν ᾐ. ...” -
The Twelve Apostles-Didache
“... [English] (14) 1. According to Lord’s own of [the] Lord, gather, break bread and give thanks, having confessed your faults before, that your offering be pure. ...”
The original Greek of Didache 14:1 does not have the words for “day”, “days”, “Sunday”, “day of the sun”, “first”, “one”, “week”, “first [day] of the week”, “the Lord’s day”, the “eighth day”. The often proffered translation of the Didache into English that most propose to prove ‘Sunday sacredness’, or that ‘the first [day] of the week’, is the ‘Lord’s day’, is quite imaginary, or at the very least extremely interpolative. Even if the meaning is “the Lord’s [day] of Lord” it does not indicate which “[day]” is meant. It might mean the “Resurrection [day] (ie. what some call ‘Resurrection Sunday’, or ‘Easter’)”, being one day in the year during the ending of the Passion week. It might mean a weekly “[day]”, which just as well could be the 7th day, the Sabbath day, or the true Lord’s day (Isa. 58:13; Rev. 1:10 KJB). It might even mean the “Lord’s [feast-supper] of [the] Lord”, in which persons could gather on any day and partake of throughout the year, not merely weekly. It could mean a weekly meeting on the first [day], but there is no definitive contextual demonstration of such. Anyone who says otherwise, is simply not being honest with the Greek text at hand."
It could even be referring to people, the disciples "the Lord's own", etc. In other words, follow their instruction / example after the Lord (Jesus), and their instruction / example was sabbath keeping. See the resources in the links.
Act. 20:7 does
not begin on "sunday" (midnight to midnight, Roman time), but begins 'saturday night' (which is scriptural 'first [day]' time), as it says, "many lights in the upper chamber", and later "midnight", &c.. I also address that specific text in what it says in both koine Greek and in English in a section of the book as well. Did you read that? If not, why not? Do you not want to see a response to the common errors people bring up (such as you just did, not knowing the details)?
Acts 20:7 is a one-time event, beginning saturday night, after sunset, when the 7th day sabbath had ended, and Paul and the disciples at Troas, met again after sundown to have a final farewell meeting and fellowship meal, since Paul was leaving them ("ready to depart on the morrow"), pretty much permanently after that. The context is the 7 weeks (7 sabbaths) unto Pentecost, which is why the koine Greek says, "εν δε τη μια των σαββατων" (in of the first/one [of] the sabbaths (plural)), since it was the first day of the first week of 7 sabbaths, counting towards Pentecost; see
Act 20:16 For Paul had determined to sail by Ephesus, because he would not spend the time in Asia: for he hasted, if it were possible for him, to be at Jerusalem the day of Pentecost.
Pentecost, known in scripture as shavuot, or the 'feast of weeks' (7 sabbaths, + 1 day; Lev. 23:15-22). This was a
once in the year event (a typology of the true Pentecost in Acts 2.).
Acts 20 is not a weekly reoccurence. Why do you make it one? If you attempt to follow this pattern as a weekly example, do you:
1. Meet at a house gathering at night, 'saturday night' after having kept sabbath (see koine Greek) the day before?
2. Does your pastor preach until midnight?
3. Do you have a common meal at night (Act. 2:46; 20:7), and again at around midnight (Act. 20:11)?
4. Does the guest evangelist continue to keep preaching until sunrise (sunday morning)?
5. Does the guest evangelist leave, and walk to his next meeting at sun up ('sunday morning')?
Please, see pages 47 - 50, as it is only a few (4) short pages of the details, as there is a lot more I would ask you about that text, in its proper context -
