We can, with good will, argue over Sabbatarianism and Judaizing generally. We can lament the anti-Semitism of that age, of this age, and of intervening ages.
But we are not going to get anywhere useful if you guys don't get that practices aren't initiated by their prescription. Councils and the like more often resolve conflicts than initiate new practices. Many many Catholics believed in the real presence before the doctrine was defined. It is the same for the Marian Dogmata, and it was the same for Sunday worship and quartodecimanism. TO point to a document and say it represents the beginning of a practice is to make an assumption, not an argument.
Yah'shua recommends rebuke in NAsbU 1 Timothy 5:20 Those who continue in sin, NAsbU 2 Timothy 4:2 preach the word; When man-made tradition impugns the Word of G-d.

it should be rejected, nay rebuked as Yah'shua rebuked the Pharisees. NAsbU Luke 17:3 "Be on your guard!
or Paul
If your brother sins,
rebuke him; and
if he repents, forgive him. NAsbU 1 Timothy 5:1 Do not sharply rebuke an older man,
or any of the following:
but rather appeal to him as a father,
to the younger men as brothers,
rebuke in the presence of all,
so that the rest also will be fearful of sinning.
be ready in season and out of season;
reprove, rebuke, exhort,
with great patience and instruction.

You tried to make an argument from Constantine. When it is suggested that MAYBE you are misinterpreting the evidence, you change the subject.
I don't play that game.
I say again, to say that, for example, worship on the Lord's day was instituted by Constantine on the basis of some edicts is to misunderstand the relationship between edicts and behavior and to assume that the edicts CAUSE the behavior. This is an error.
There MAY or MAY NOT be other errors we are making. But it's silly to go off after them before we resolve this one. Do you wash only some of the dishes and then go and mop only part of the floor before you make one half of the bed?
