We've almost completed the circle. (Stay with me and we'll walk the rest of it together.)
Show me the specific line in the New Testament (and not the vague catch-all line that allows everything but idols and meat from strangled animals) that shifts the day of rest from Saturday to Sunday.
From pentecost, when believers were first baptized into the body of Christ - which was a Sunday - onward - the NT records believers gathering on the first day of the week.
Yes, a Apostles went on the sabbath to witness to gatherings of Jews, as commanded of them.
That Sunday gathering for Christian worship continues onward in the early church record for 300 years.
You’ve made up an argument about the authority of Rome being necessary to change to Sunday worship that is simply false.
It isn’t credible.
There was no decree issued in the NT. The Holy Spirit came on Pentecost.
No Rome needed.
Show me the specific line in the New Testament ...You've probably heard the following in Mass before; but it never sank in...
Romans 14:1-12 Douay-Rheims Bible
1 Now him that is weak in faith, take unto you: not in disputes about thoughts. 2 For one believeth that he may eat all things: but he that is weak, let him eat herbs. 3 Let not him that eateth despise him that eateth not: and he that eateth not, let him not judge him that eateth. For God hath taken him to him. 4 Who art thou that judgest another man's servant? To his own lord he standeth or falleth. And he shall stand: for God is able to make him stand.
5 For one judgeth between day and day: and another judgeth every day. Let every man abound in his own sense. 6 He that regardeth the day regardeth it unto the Lord. And he that eateth eateth to the Lord: for he giveth thanks to God. And he that eateth not, to the Lord he eateth not and giveth thanks to God. 7 For none of us liveth to himself: and no man dieth to himself. 8 For whether we live, we live unto the Lord: or whether we die, we die unto the Lord. Therefore, whether we live or whether we die, we are the Lord's. 9 For to this end Christ died and rose again: that he might be Lord both of the dead and of the living.
10 But thou, why judgest thou thy brother? Or thou, why dost thou despise thy brother? For we shall all stand before the judgment seat of Christ.
11 For it is written: As I live, saith the Lord, every knee shall bow to me and every tongue shall confess to God.
12 Therefore every one of us shall render account to God for himself.
