Point 8 - resurrected scripture shows us that this tradition dates all the way back to the very first Christians with Saint Paul speaking of a collection being taken up and the act of the Apostles describing the time to break bread both of which taking place on the first day of the week"
The OP has not carefully read saint Paul's Epistle to the Corinthians (1 Cor. 16:1-2, &c) then. Look at what it says, teaches, and most definitely does not say:
1Co 16:1 Now concerning the collection for the saints, as I have given order to the churches of Galatia, even so do ye.
1Co 16:2 Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.
1Co 16:3 And when I come, whomsoever ye shall approve by your letters, them will I send to bring your liberality unto Jerusalem.
1Co 16:4 And if it be meet that I go also, they shall go with me.
1 Corinthians 16:2 GNT TR - κατὰ μίαν σαββάτων ἕκαστος ὑμῶν παρ᾽ ἑαυτῷ τιθέτω θησαυρίζων ὅ τι ἂν εὐοδῶται ἵνα μὴ ὅταν ἔλθω τότε λογίαι γίνωνται
[01.] 1 Corinthians 16:2, says nothing of a regular weekly meeting by anyone on “the first [day] of the week”, at ‘church’ ,’synagogue’ or any other location.
[02.] The Apostle Paul (Romans 1:1, 11:13; 1 Corinthians 1:1, 9:1-2, 15:9; 2 Corinthians 1:1, 12:12; Galatians 1:1; Ephesians 1:1; Colossians 1:1; 1 Timothy 1:1, 2:7; 2 Timothy 1:1,11; Titus 1:1) never once designates the “first [day] of the week” as “the sabbath” (the 7th day), or even a replacement for “the sabbath”, or that the sabbath was no longer “holy”, or to be kept as such by the follower of God, or no longer the (4th) “commandment” of God (Exodus 20:8-11; Deuteronomy 5:12-15) to be obeyed by Christians (Jews & Gentiles), in any part of the book of Acts of the Apostles, which records the entire history from the time of Jesus to the time of the death of Paul in Rome (Acts 28:16,30; 2 Timothy 4:6-8), or in his Epistles (Romans to Hebrews). Paul simply calls the day the “first”, even as the people of God have from the beginning.
[03.] Paul never identifies the “first [day] of the week” as “the Lord’s day” (Revelation 1:10; really the 7th day the sabbath of the LORD, see Isaiah 58:13; Mark 2:27; &c.) anywhere in the book of the Acts or his Epistles (Romans to Hebrews).
[04.] Paul in the book of Acts, and in his Epistles (Romans to Hebrews) meets with Jews, Gentiles and Christians upon the ”sabbath” (the 7th day) many times (Acts 13:14,27,42,44, 15:21, 16:31, 17:2, (3 consecutive sabbaths) 18:4 (“every sabbath”; also vs 11, a “year and six months”, which is 52 weeks + 26 weeks, being 78 consecutive sabbaths met together on by both Jew and Gentile with the Apostle Paul and others, and in Acts 18:23, “he had spent some time there” (several sabbaths); in Act 19:8, “for the space of three months” (12 sabbaths); in Acts 19:10, “continued by the space of two years” (104 sabbaths), “in Acts 19:22, “for a season” (several sabbaths), in Acts 20:3, “three months” (12 sabbaths), and in Acts 20:7 (afterward, meets with the disciples again that night which begins the next day), and in Acts 20:18,31, “all seasons, ”a space of three years” (156 sabbaths)), and in Romans to Philemon (Romans 1:18, 2:26-27, 3:31, 6:1-23, 7:7,12,14,16, 8:4-14, 9:6-8,27,31,32, 11:1-36, 12:1,2,5,9, 13:8-14, 15:1-27, 16:17-19; 1 Corinthians 9:21; Ephesians 6:2; 1 Timoth7 1:8; Galatians 2:18, 5:14; [01.] [Ex. 20:1-3] Acts 14:15-16, 24:14; 1 Corinthians 8:5-6; [02.] [Ex. 20:4-6] Acts 15:20, 17:29; 1 Corinthians 10:7,14, 12:2; 2 Corinthians 6:16; 1 Thessalonians 1:9; Galatians 5:20-21; Ephesians 5:5; Colossians 3:5; [03.] [Ex. 20:7] Romans 2:24; Colossians 3:8; Ephesians 5:4; 1 Timothy 6:1; [04.] [Ex. 20:8-11] Acts 13:14-16,42,44, 14:15-16, 15:21 (see Isaiah 56:6) , 16:13, 17:2 (compare Luke 4:16), 18:4,7 (see John 16:2),11 (over 78 sabbaths kept consecutively, with Jews, Gentiles and whole city at least once); Hebrews 4:1-12 (especially vs 9; “rest” = koine Greek “σαββατισμός”, “sabbatismos”), 10:25 (the Lord’s day, the 7th day in weekly cycle and also the greater ‘Day of the LORD’, the 1000 years); [05.] [Ex. 20:12] Ephesians 6:1-3; Colossians 3:20; [06.] [Ex. 20:13] Romans 1:29,32, 13:8-10; [07.] [Ex. 20:14] Romans 13:8-10 Colossians 3:18-19; [08.] [Ex. 20:15] Romans 2:21, 13:8-10; Ephesians 4:28; [09.] [Ex. 20:16] Romans 13:8-10; Colossians 3:9; [10.] [Ex. 20:17] Romans 1:29,32, 7:7, 13:8-10; Ephesians 5:3; Colossians 3:5; Hebrews 13:5), Paul always magnifies the Law of God, the Ten Commandments to be kept by the Christian, and in Hebrews 4:1-12 shows that true sabbath-keeping continues from the beginning of the foundation of the world for the Christian).
[05.] Paul never states (explicitly, or implicitly) in any location (Acts or Epistles of Paul) that Christians were to gather merely upon “the first [day] of the week” in honour of Christ’s resurrection. Paul specifically records that Christians honour Christ’s resurrection through an event, called “baptism” (Romans 6:1-23; Colossians 2:12).
[06.] Paul makes direct mention of the “first [day] of the week” only 1 time in his Epistles (1 Corinthians 16:2), and also meets with some believers at an evening (night) meeting thereupon, as recorded by Luke (Acts 20:7). Paul never actually met with anyone, or preached, in the Corinthian church upon the “first [day] of the week” in the context of 1 Corinthians 16:1-10, even as he says, “For I will not see you now by the way …” (vs 7).
[07.] In 1 Corinthians 16:2, (and context) neither did any of the believers meet together upon “the first [day] of the week”, for the text in plain English reads, “let every one of you lay by him in store, as [God] hath prospered him”, which is a personal matter to be done as an individual, in the privacy of their own homes or households, taking stock of their own personal goods. Even the koine (common) Greek reads just as emphatically, “ὑμῶν παρ᾽ ἑαυτῷ τιθέτω θησαυρίζων ὅ τι ἂν εὐοδῶται” [umon par [h]eautw tithetw thesaurizwn o ti an euodwtai]. The words are in the ”singular” (ie. Individual persons),”let” (V-PAM-3S), ”every one” (A-NSM), “lay” (V-PAM-3S), “him” (F-3DSM), “in store” (V-PAP-NSM), “as” (R-ASN), (Gr.) “ti” (X-ASN), “hath prospered him” (V-PPS-3S).
[08.] The “in store” (θησαυρίζων [thesaurizwn; G2343; V-PAP-NSM]) is not the collective ‘storehouse or treasury’ of the collective church body, but rather the individual and personal storage place of their own goods at their home and household. After the Sabbath was over, the individual persons, were to take inventory of their prosperity (given them by God), and put something extra (beyond their tithe/firstfruits and general offerings to God) aside for those in Jerusalem (vs 3), for Paul was determined to be thereby Pentecost (vs 8; see also Acts 18:21).
[09.] The special (extra, beyond tithe and general offerings, “as God hath prospered”) “collection” (vs 1), or “gatherings (of liberality)” (vs 2-3), are not commanded to be given by the believers in Corinth or Galatia (vs 1) at all seasons, or for all of time. The context of the special request for a collection to be taken later from individuals, was for those specifically in “Jerusalem” (vs 3), and no other place was mentioned. Why? It was because there was a “great dearth” (Acts 11:28), and many “poor” (Galatians 2:10; Romans 15:25-33) there. Paul, as he went about, and wrote, had asked believers in several places about this timely subject (2 Corinthians 1:15-16, 8:1-24, 9:1-5; Acts 11:27-30, 24:17; Romans 15:25-33; Galatians 2:1,10, 6:9-10). Paul, when he finally arrived in their area, would send specially chosen persons by those congregations to Jerusalem with those means (vs 3) that had already been put aside each week, all that time from the time Paul asked, for that purpose (vs 2). The event is recorded as an example of what can be done for special cases of emergency when they arise.
[10.] The Corinthian believers in 1 Corinthians 16:2 (and context) neither meet together for “the Lord’s Supper” (1 Corinthians 10:16-21, 11:20).
The context even lacks those additional things and phrases which accompanied it:
[I.] “cup” (Exodus 24:11 (“drink”); 1 Chronicles 28:17; Jeremiah 52:9; Matthew 26:27; Mark 14:23; Luke 22:17,20; 1 Corinthians 10:16,21, 11:25-29);
[II] “fruit of the vine” (pure juice of the grape; Matthew 26:29; Mark 14:25; Luke 22:18; 1 Corinthians 10:16 (“blessing”);
[III] “Lord’s table” (Exodus 35:13, 39:36; Leviticus 24:6; 1 Kings 7:48; 2 Chronicles 4:19, 13:11, 29:18; Ezekiel 41:22; Malachi 1:7,12; 1 Corinthians 10:21);
[IV] “Lord’s supper” (1 Corinthians 11:20,21; Luke 22:20; John 13:2,4, 21:20; Revelation 19:9);
[V] “wash the disciples feet” (John 13:5-17; 1 Timothy 5:10);
[VI] “water” (John 13:5);
[VII] “servant (‘service’)” (John 13:16);

[IX] “testament” (Matthew 26:28; Mark 14:24; Luke 22:20; 1 Corinthians 11:25; Hebrews 9:11-28);
[X] the significance of the “Lord’s supper” was not to show the resurrection, but rather the “Lord’s death” (1 Corinthians 11:26).
[11.] The context even reveals that there was nothing that is associated with common congregational meeting. There was no:
[I.] “worship” (Isaiah 66:23; Mathew 2:2; John 4:21,23-24; Acts 24:14; &c.);
[II] “temple” (Malachi 3:1; Acts 2:46, 3:1,2,3,8,10, 4:1, 5:20,21,24,25,42, 21:26-30, 22:17, 24:6,12,18, 25:8, 26:21, &c.);
[III] “Synagogue” (Mathew 13:54; Mark 1:21,23,29, 3:1, 5:22,36,38, 6:2; Luke 4:16,20,28,33,38, 6:6, 7:5, 8:41, 13:14; John 6:59, 9:22, 12:42, 18:20; Acts 6:9,
13:14,15,42, 14:1, 17:1,10,17, 18:4,7,8,17,19,26, 19:8, 22:19, 26:11; Revelation 2:9, 3:9);
[IV] “house to house” (Luke 10:7,38; Acta 2:46, 16:15, 20:20; 1 Timothy 5:13) or “upper room/chamber” (Mark 14:15; Luke 22:12; Acts 1:13, 9:37,39, 20:8);
[V] “meeting” (Isaiah 1:13) or “convocation” (Exodus 12:16; Leviticus 23:3,7,8,21,24,27,35,36; Numbers 28:18,25,26, 29:1,7,12);
[VI] “Lord’s Supper” (1 Corinthians 11:20,21; Luke 22:20; John 13:2,4, 21:20; Revelation 19:9);

[VIII] “prayers” [collectively, or individually] (Acts 2:42, 10:4, 11:5, 12:12; Romans 1:9, 15:30; 1 Corinthians 11:4; 2 Corinthians 8:4; Ephesians 1:16, 6:18;
Colossians 1:3, 4:13,2; 1 Thessalonians 1:2, 3:10; 1 Timothy 2:1, 5:5; 2 Timothy 1:3; Philemon 1:4,22; Hebrews 5:7; 1 Peter 3:7,12; Jude 1:20; Revelation 5:8,
8:3-4);
[IX] “supplications” (2 Chronicles 6:21,39; Psalms 28:2,6, 31:2, 86:6, 116:1, 130:2, 140:6, 143:1; Jeremiah 3:21, 31:9; Daniel 6:11, 9:3,17,18,20,23; Hosea 12:4;
Zechariah 12:10; Acts 1:14; Ephesians 6:18; Philippians 4:6; 1 Timothy 2:1, 5:5; Hebrews 5:7; &c);
[X] “confession” [of sins to God, or faults to one another] (James 5:16; 1 John 1:9);
[XI] “tithe” (Genesis 14:20; Leviticus 27:30,31,32; Numbers 18:24,26,28; Deuteronomy 12:6,11,17, 14:22,23,28, 26:12; 2 Chronicles 31:5,6,12; Nehemiah
10:37,38, 12:44, 13:5,12; Amos 4:4; Malachi 3:8,10; Matthew 23:23; Luke 11:42, 18:12; Hebrews 7:5,6,8,9, &c (see “firstfruits”));
[XII] “offering” [general] (Malachi 3:4,8; Luke 21:4; Acts 24:17);
[XIII] collection “baskets” (Matthew 14:20, 15:37, 16:9-10; Mark 6:43, 8:8,19-20; Luke 9:17; John 6:13);
[XIV] church “storehouse” (Malachi 3:10);
[XV] singing, psalms or hymns (1 Chronicles 16:9; Psalms 95:2, 105:2; Ephesians 5:19; Colossians 3:16; James 5:13);
[XVI] “exhortation” (preaching and/or teaching) (Luke 3:18; Acts 13:15, 16:2, 20:2; Romans 12:8; 1 Corinthians 14:3; 2 Corinthians 8:17; 1 Thessalonians 2:3; 1
Timothy 4:13; 2 Timothy 4:2; Hebrews 12:5, 13:22);
[XVII] reading from the word of God (Luke 4:16;Acts 13:15; 2 Corinthians 3:14; 1 Timothy 4:13);
[12.] Even if 1 Corinthians 16:2 is to be taken as a ‘pattern’ for weekly, or continual, behavior among Christians meeting for service in worship (which it shouldn’t be, as no one who incorrectly thinks to make it about a weekly gathering of the body of Christ Jesus into one place in a worship setting actually follow to the letter what is written therein), then what takes place therein, is persons staying at home, as individuals, on the “first [day] of the week”, and taking account of personal business of the house, after the Sabbath was over, to determine how much they have been prospered of God, so that they can later assist only those who are poor in the earthly city of Jerusalem during a time of want, as foretold by the prophet Agabus (Acts 11:28) and others, while all of the other things associated are left out altogether (singing, prayer, reading the word, preaching, teaching, exhorting, etc).
